Designed to be our highest flowing Check Valve to date!

Fully Machined and Assembled in our shop using 6061-T6 Aluminum, and anodized BLUE or BLACK for a durable, corrosion-resistant anodic oxide finish.

This one-way aluminum check valve is used to allow flow in one direction but prevent flow in the opposite direction. The most common use is preventing fuel from returning to the tank after a pump is turned off, maintaining rail pressure, and as an addition to your Forced Induction or Turbocharged application.  Another common use is as a vacuum line check valve to maintain accuracy of airflow measurement sensors or prevent pressure buildup.

Combined with our Elite Engineering Catch Can kits, we recommend our Check Valves to be installed on the Exit side of the Catch Can flowing AWAY from the Catch Can.  Designed to open and close to always default to the strongest suction source at the time providing full time crankcase evacuation instead of only when not accelerating or at WOT when no vacuum is present
Our check valves can be used can be used with any Diesel, Oil, Water Coolant, Air, Gasoline, or other materials compatible with aluminum.

Some key features:

  • Includes laser etched flow direction arrow
  • Measures less than 3" in overall length.
  • Maximum operating pressure: 150 psi
  • Operating Temperature range: -30F to 410F
  • Hose Barb Ends

    Nice Check Valve

    Posted by Unknown on 17th Aug 2020

    I could see this is a nice high flowing sturdy check valve with not many moving pieces that could get stuck or break. They also offer it in a 1/2 inch size which is nice for certain situations.

    Best valve at best value

    Could not find a decent check valve to manage the PCV for my boosted system; this fits the bill perfectly.

    High Quality Check Valve

    Posted by Marland M on 18th Nov 2019

    I doubt there can be a better check valve found. Had to use a check valve in the PCV system for my boosted vehicle. This being a check valve I couldn't believe there was no flow restriction. I had another brand check valve but it had restriction so bad that the PCV system wasn't working correctly. It works perfect now with the Elite valve. Thanks Elite!

    This is absolutely the best check valve on the market

    Posted by brad k on 3rd Jun 2019

    My turbo vehicle had an issue blowing apart the PCV valve. I didn't want to take the risk of it throwing the parts into the valve train so I scoured the internet looking for a one-way check valve. Google wasn't very helpful and always pointed me to ( Amazon! All you get is a cheap part that has so much restriction so don't waste your money) From different articles I've read I then stumbled across elite engineering. I received this high flow One way check valve super quick and was totally blown away on the build quality and feel hope this check valves.. also how free-flowing this valve is. Read the description of this check valve and you will understand why I am so happy with this purchase, knowing that my engine will be protected without any doubts. I'm a first-time customer and also going to be a long time customer after the service I received.. keep it up elite!
