    Check Valves with Push-to-Connect Fittings for Harsh Chemicals

    Image of Product. Back orientation. Check Valves. Check Valves with Push-to-Connect Fittings for Harsh Chemicals.
    Connect your inlet tubing into the push-to-connect fittings—no heat, solder, or flux required. These valves have a PVDF body and a fluoroelastomer seal for excellent chemical resistance. They open to allow flow in one direction and close when flow stops or reverses.
