    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.

    Clear-View Socket-Connect Check Valves for Harsh Chemicals

    Visually inspect flow and debris accumulation through the transparent valve body. Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. Valves have a PVC body and a fluoroelastomer seal for excellent chemical resistance. They open to allow flow in one direction and close when flow stops or reverses. All have a removable cap that provides easy access to internal components for maintenance.
