SMC 3/8" Heavy Duty Check Valve


1 review

This SMC check valve 3/8" is a lifesaver. If you have ever had bags, you’ll know how much it would stink for your truck to be sitting on its frame when you wake up one morning. The fact is, accidents sometimes happen and having a fail-safe is always the best idea.

These heavy duty check valves provide a means for your vehicle to stay lifted even if your air system fails while still providing a full-force 3/8″ air flow. Don’t risk becoming a beached whale.. it really isn’t as much fun as it sounds.

What Is a Check Valve?

A check valve is a critical part of any air compressor system. A check valve ensures that air can only flow one-way through it. In an air system, it normally sits between an air tank and an air compressor and prevents tank pressure from leaking back through the air compressor. Without this, it would take much longer to fill your air tank, leave the potential for leaks to occur, and even damage your air compressor.
