Designed from the ground up, our new nozzle addresses the common flaws found in existing market options. Our goal was to create a high-quality nozzle with an easy-to-service built-in check valve at a competitive price, and we have accomplished just that.
Essential Features:
- Small compact design
- Built-in check valve
- Easy to serviceand rebuild
- 100% methanol compatible
- Highly corrosion resistant
- 1/8 NPT thread
- Adjustable flow rate
- 10 micron filter basket
- Completly sealed design
- Orifice marked on the outside
Existing Nozzle Flaws Corrected:
- Replacing soft brass material with hard stainless steel
- Eliminate soft brass prone to stripped threads
- Eliminate nickel plating which eventually wears or flakes off clogging nozzles
- Eliminate corrosion-prone brass with highly corrosion resistant 316 stainless steel
- Eliminate the coarse screen mesh filter with a proper 10 micron pressed in filter to further help eliminate nozzles from becoming clogged and failing
Follow along as we break down all the features of our new stainless steel 1/4" extended tip nozzle with built-in check valve and why you would choose this nozzle.

316 stainless steel is vastly superior to the brass and aluminum water methanol injection nozzles used by our competitors in terms of strength, hardness, corrosion resistance, and longevity. While it is a more expensive material, 316 stainless steel is arguably the best choice for machining
water methanol injection nozzles. Our water methanol injection nozzles can be disassembled, cleaned, reassembled indefinitely without the risk of stripping the threads or rounding off the 7/16" hex head, common issues found with competitor nozzles.
Our water methanol injection nozzle cartridge is constructed from 316 stainless steel and is designed to be inserted directly into the nozzle. When fully inserted, the cartridge makes contact with the atomizer to ensure it is centered and properly seated against the nozzles orifice. At the top features a custom-made, press-fit, 10-micron stainless steel filter, which is the same style used in OEM fuel injectors. This filter prevents particles 0.0003 and larger from passing through. Additionally, an EPDM o-ring along the side ensures a fully sealed, filtered design.
Lastly, the cartridge assembly houses the sliding check valve piston and spring. This easy to service and repair check valve design makes it easy for customers to clean and rebuild when needed.

The purpose of the water methanol injection nozzle cartridge spring is to maintain constant downward pressure on the nozzle cartridge and atomizer. A pad is located at the top of the nozzle cartridge for the spring.
When the water
methanol injection nozzle is screwed into the nozzle holder, the spring makes contact with the interior of the nozzle holder, pushing the nozzle cartridge downward. This constant pressure ensures the atomizer remains firmly seated against the orifice, maintaining a proper spray pattern regardless of vibrations or boost.


The primary function of the water methanol injection nozzle atomizer is to spin the fluid immediately prior to its exit from the orifice, resulting in a hollow cone spray pattern. The atomizer also regulates the nozzle's flow rate; increasing the number of slots permits greater fluid volume into the spinning chamber, while fewer slots reduce the flow.
Users may adjust the flow rate within established parameters for each orifice size by changing the atomizer. This provides a cost-effective alternative, particularly for water methanol injection direct port users, as it removes the necessity of purchasing multiple complete nozzles when wanting to make a flow adjustment.

What makes our new nozzle truly exceptional is the optional built-in check valve. This feature is a game-changer for the water-methanol injection industry and direct port users.
Machined from 316 stainless steel, the nozzle features a compact sliding piston that can be easily cleaned and reused indefinitely. A bubble-tight seal is provided by an EPDM O-ring, and replacement O-rings are available for individual purchase when needed. Each check valve is equipped with a 25 psi opening spring.

We aimed to offer the most extensive range of water methanol injection nozzle flow rates on the market, and we have achieved just that. With over 90 different flow rates available, Users can now fine-tune their water methanol injection systems and methanol injection direct ports setups with unprecedented precision.
Our new modular design allows users to change either the internal nozzle atomizer or the nozzle body orifice size to create a vast variation of different flow rates. This provides a more affordable way to adjust flow rates without the need to purchase complete nozzle assemblies every time. Furthermore, when you purchase a
ProMeth water methanol injection nozzle, you are investing in a product designed to last a lifetime, especially when compared to the soft brass nozzles throw away nozzles provided by competitors
While competitors often claim to offer superior quality and performance water methanol injection nozzles, these assertions are frequently unsubstantiated by any pictures, evidence or any documentation. Furthermore, claiming superiority while utilizing nozzles machined from brass and aluminum is inconsistent with high-performance standards.
Do not be misled by marketing hype. With nearly 20 years of experience in the water methanol injection industry, we have designed our water methanol injection nozzles based on extensive experiance and understanding the flaws of existing nozzles on the market. Our nozzles are not an off-the-shelf agricultural nozzle, nor does it contain plastic components prone to failure. If you are looking for the best water methanol injection nozzle on the market, look no further.
