Tank Couplings

The aluminum tank coupling is a female tapered threaded coupling with a 2 claw holding style. Different size pots and different size metering valves will require different size tank couplings, such as these 1-1/4 in., 1-1/2 in., and 2 in. couplings. Any “standard” large claw size hose coupling will match up to these fittings. NECO aluminum tank couplings have a 150 psi rating. Each tank coupling comes complete with a gasket.
