    Features:

    • This simple valve system when incorporated in the top of a vented loop allows air to enter the line when it is not in use
    • Then it effectively seals as water or other fluid passes through
    • Molded in Marelon®, vent will not corrode
    • The duckbill one way valve is designed to seal properly if particulate matter is present in fluids
     

    General Note: Forespar threaded plumbing fittings (like most true marine plumbing fittings) use NPSM Threads - National Standard Free-Fitting Straight Mechanical Pipe Thread. NPT - National Pipe Threads are tapered, NPSM Threads are parallel. The two types are not designed to work together.
