We Compare Our New Flat Tip Stainless Steel Nozzle To Our Original Brass Nozzle

Posted by Rodney Michels on

 

Why did we discontinue our original nozzle? 

With nearly 16 years of experience and over 10,000 units sold, we have gained a deep understanding of our original brass nickel-plated nozzle. We sourced this brass nickel plated nozzle from a company in the US called Monarch Manufacturing Works. It was an agricultural nozzle we were able to buy in different flow rates. In recent years. Identical copies are now being mass produced in China and can be purchased from AliExpress and Temu for $25. 

Our new stainless steel nozzle is the result of our commitment to performance and quality. Key improvements include enhanced flow control, affordable adjustable flow options, consistent spray patterns, increased durability and longevity.

We believe this new design offers significant benefits over the previous version. Please follow along as we compare the two nozzles and share the inspiration behind these enhancements. This is what innovation looks like. 

Why is brass not good? 

Brass is a relatively soft material, making threads susceptible to stripping or damage. Additionally, hex heads can round off over time with wrench use. We have also found that over-tightening brass threaded filter can inadvertently crush the small internal brass atomizer, which reduces the nozzle's flow rate or completely shuts the nozzle off.

Furthermore, brass is prone to corrosion that can lead to clogged nozzles. Specifically, the copper in the alloy reacts with moisture and air to create green patination. The atomizer and some surfaces of the nozzle interior and orifice are machined after nickel plating. These raw unplated brass surfaces will be vulnerable to this corrosion.

 

This issue is particularly apparent when customers store their vehicles for the winter. During these periods of inactivity, the nozzles frequently corrode and clog shut. This is especially problematic for direct port users, as this would require the direct port to be completely removed in order to clean all the nozzles. 

Why were our original water methanol injection nozzles made from brass? 

We did not design or manufacture our original brass nickel plated nozzles. These nozzles were sourced from Monarch Manufacturing Works. Several water methanol injection companies have purchased this nozzle from Monarch Manufacturing Works.  These nozzles were intended for agricultural use, specifically for spraying water. They were not designed for use with corrosive fluids like methanol.

The primary reason for using brass is that it is significantly more cost-effective to manufacture. Because brass is a softer material, it can be machined much faster than stainless steel. This results in less wear on cutters, less tool sharpening, fewer tool breakages, and reduced machine downtime. Ultimately, a higher volume of parts can be produced from brass compared to stainless steel in the same amount of time. 

Nickel plating. While nickel plating certainly provides a higher-quality appearance compared to plain brass, I recommend avoiding it for a few reasons. The primary issue is that the nickel plating lacks durability and tends to flake off over time, potentially clogging the nozzles. Remember, as stated earlier. Some interior surfaces of the nozzle are nickel plated. Additionally, plated nozzles are incompatible with ultrasonic cleaners because the cleaning process will remove the coating entirely.



Why did we eliminate the threaded filter design?


Surprisingly, the threaded filter feature on our original brass nickel plated nozzle has many issues associated to it. 

One, if the filter vibrates loose, it fails to keep the internal atomizer seated against the orifice. Consequently, when the nozzle is pressurized. The atomizer will become unseated and float ovr the orifice. Fluid flows freely around the atomizer, bypassing the slots intended to spin the fluid and compromising the nozzle's performance.

If the fluid is not spinning before exiting the nozzle orifice, the nozzle will no longer spray a hollow cone spray pattern. Instead, it will produce a solid stream. This causes the nozzle and the overall performance of the water-methanol injection system to fail, inconsistent, making it difficult and confusing for customers to diagnose.

Next, customers over-tighten the filter, unknowingly crushing the soft brass internal atomizer. This leads to reduced flow or completely shutting the nozzle off. It doesn't take much to pinch off the small thin slots on the face of an atomizer.

Next, threaded filters are prone to creating microscopic metal shavings. Each time they are threaded and tightened, the friction between the two metal surfaces causes wear, which can result in the release of these shavings.

Next, the original nozzle are equipped with a 170 mesh screen rather than a true filter. The openings between the woven wires are visible without magnification, and while the screen is effective at stopping debris of 0.007 or greater, it does not effectively filter particulates or prevent nozzle clogging.

Our new nozzle uses a press-fit 10-micron stainless steel filter. Filtering out particulates 0.0004" or larger. Making it very effective at preventing any particulates from passing through the nozzle and potentially clogging the nozzle. This is the same filter technology used with OEM fuel injectors.

Finally, consider the difficulty of cleaning the nozzle. It's very hard to clean female threads inside the nozzle and confirm they are clean. This was another benifit to removing the threaded filter. 

How does the old atomizer compare to the new atomizer?

The original brass nozzle included a small, raw brass internal atomizer that was not nickel-plated. This design required fluid to flow around the atomizer's outside diameter to reach the slots on the face, necessitating significant clearance between the atomizer and the nozzle's inside diameter.

Consequently, the atomizer fit loosely inside the nozzle and often failed to sit squarely on the seat upon insertion. As a result, the filter had to be screwed in to properly align and secure the atomizer against the seat.

We successfully improved the atomizer by redesigning it from scratch. Key changes include:

- Material: We are pleased to announce that our new atomizer is now manufactured from 316 stainless steel. This material provides high corrosion resistance and exceptional durability. Our atomizer will never rust or corrode no matter how long the vehicle sits inactive. Unlike our previous brass atomizer, this new version is also very resistant to damage from wire brushes, ultrasonic cleaners and normal wear and tear.  Its flow rate will remain consistent and will not be affected.

- Precision Fit: We designed the unit to fit precisely within the nozzle with a 0.002" side-to-side clearance, ensuring it remains squarely seated against the orifice every time for consistant reliable spray patterns everytime. 

- Improved Flow: The fluid now flows through the center of the atomizer then outward through four channels into a circular chamber. Located just beneath the slots, this cicular chamber ensures a constant fluid supply to the slots. Additionally, the larger atomizer design accommodates a greater number of slots to support higher-flowing nozzles which wasn't avaialble with the previous brass nozzle. 

 

Adjustable flow rate nozzles. What does that mean?

Each nozzle can have its flow rate adjusted within a set parameter specific for that orifice by changing the internal atomizer. Atomizers come with different number of slots. More slots equeals more flow. Less slots equals less flow. Customers no longer need to buy complete nozzle assemblies to have different flow options on hand. Customers can buy the atomizers seperatly to change the nozzles flow rate for much less money. This can be very benificial for direct port users saving them lots of money. 

We have a total 9 different atomizers available. We have over a 90 different nozzle flow flow options available providing customers the ability to fine tune their water methanol injection sysstems and direct ports. 

Sealed nozzle design. Why does that matter?

We designed our nozzles with a oring around the outside diametr of the cartridge. When the nozzle cartridge is inserted into the nozzle. The only way for fluid to pass through the nozzle is through the 10 micron pressed-fit filter. We wanted to make every effort to prevent any unfiltered fluid from passing through the nozzle. 

What is the purpose of the spring?

The purpose of the spring is to apply constant downward pressure on the internal atomizer. When you screw the assembled nozzle with spring into our nozzle holder. The spring will make contact iinside our nozzle holder.pushing the nozzle cartridge downward against the atomizer. This ensures the atomizer is always seated against the orifice no matter the vibrations of how much boost someone is running. 

What is the advantage of selecting orifice size?


The only nozzle that allows you to control and select the orifice size. Why is this important?

This is very beneficial to direct port users and anyone using small orifice low flow rate nozzles. For example, direct ports commonly use very small nozzles. These smaller nozzles are prone to clogging due to their very small orifice size.

To resolve this, we determined that the most effective solution is increasing the orifice size while using an atomizer with the fewest number of slots. This combination allows us to use a much larger orifice, often double in size, which significantly reduces the risk of clogging while still meeting the required low flow rate. The larger orifice also produces a wider spray pattern for better atomization. 


Are the new nozzle interchangable with the old nozzles? 


Yes, both nozzle share 1/8 NPT thread on both ends and are interchangable. 

Why should you buy our water methanol injection nozzle over competitors nozzle?

True innovation stems from a deep understanding and extensive experience with water-methanol injection systems. One look at our Instagram account vs our competitors' reflects this. Nobody has more experience working directly with water methanol injection and setting up direct ports than we do. Our new stainless steel nozzle reflects this commitment to performance and quality, offering significant advancements over previous designs.

Our new stainless steel nozzle further reflects our commitment to performance and quality. Key improvements include the following:

- Increased durabilty 
- Increased longevity
- Consistent performance 
- Enhanced flow control 
- Adjustable flow rates
