Check ValvesThe Damond Motorsports check valves come pre assembled with fittings in the configurations you need. We use very low cracking pressure valves, to ensure a smooth effortless operation. Alternatively the spring in these valves can be removed to allow for no cracking pressure. Common for low pressure sides of PCV systems. The 3 8" size valves come in either a barb or a push lock style fitting. The 5 8" barbed valves use plastic 90 fittings, and straight

The Damond Motorsports check valves come pre-assembled with fittings in the configurations you need. We use very low cracking pressure valves, to ensure a smooth effortless operation. Alternatively the spring in these valves can be removed to allow for no cracking pressure. Common for low-pressure sides of PCV systems. 

The 3/8" size valves come in either a barb or a push-lock style fitting.

The 5/8" barbed valves use plastic 90° fittings, and straight brass barbed fittings. 

Hose clamps are recommended on the barb style fittings, but not required for the push-lock style. The push-lock style generally does require an assembly tool to install the hose over the fittings. 

Most 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. 

Common check valve applications:

Mazdaspeed:

5/8" 90 outlet the valve used in our Stage 1 OCC kits
5/8" straight used in Stage 2 Route 2 OCC kit, or with aftermarket intake manifolds and a Stage 1 kit
3/8" straight used as an aftermarket brake booster check valve

Ford:

3/8" pushlock straight  the valve used in our Stage 1 OCC kits (requires a lot of force to seat the hose)
3/8" barb straight use if your OCC does not come with a check valve and you wish to set it up like our Stage 1 kit
