SMC 3/8" Heavy Duty Check Valve


  • This SMC check valve 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 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.

    Please Note: During installation, only use appropriate size wrench and turn 15° past hand tight using thread sealant or Teflon tape.
