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.

Shipping takes so long for a small item

Awesome check valve!

Very high quality! Replaced my 10 year old one just as preventive.

5 Stars!

Check valve worked perfectly, extremely convenient to be able to place it wherever needed, an excellent solution for our K swapped Miata. Damond handled shipping incredibly quickly as well. Will happily buy again and recommend to anyone.

Simple and effective

I was having problems with pressure from my supercharger blowing out my valve cover seal making a huge oily mess in my engine bay. After replacing the seal and installing this check valve in the outgoing hose between the catch can and the intake tube the problem is solved and my engine bay is still leak free after about 3 weeks of daily driving with about a 30 minute commute to work. Great value and good quality check valve.
