Product Details

The Damond Motorsports check valves come pre-assembled and sealed in the configurations you need. We use very low cracking pressure valves, to ensure a smooth effortless operation. 

The 3/8" barbed valves use a push-lock style fitting, where no hose clamp is needed. 

The 5/8" barbed valves use plastic 90° fittings, and straight brass barbed fittings. These are standard barbs, so hose clamps are recommended, and can be purchased here. Since the straight 5/8" barb on both ends is commonly used for low pressure crankcase venting, we modify the valve by removing the spring, to make it a true 1-way valve, with next to no cranking pressure. 

All of our OCC kits in different Stages come with check valves included. However, if you're needing more for a custom set-up, or to add one on your existing set-up, there is now an option. If you need a custom size not offered here, please contact us for a quote.

Great products

Excellent customer service. I accidentally snapped one of the fittings for the egr delete, and called customer service. They had me send it back and the fixed it for free and sent it back immediately. Also got a one way valve from them and it's great. Best company for the platform.

Chunky beast

Seriously for a check valve this is insane. I feel like it would survive a nuclear fallout so you know it won't have any issue with some damn crank case pressure! Already tight and threads are properly sealed. Just install and go. Damond never fails, except for the cartwheel they attempted for me apparently hahaha!
