This adapter has a convenient, soft nose handwheel P.O.L. on one end and a unique brass 1" 20 male swivel fitting with “0” ring and valve on the opposite end. The durable thermoplastic hose has a working pressure of 350 P.S.I. and a 1750 P.S.I. burst rating. With this hose you can quickly and safely adapt any appliance, normally fueled by small disposable cylinders to a larger, refillable L.P. vapor tank. Unlike most competitive models, swivel fittings on both ends of the hose eliminates the necessity of turning the entire hose to make the connection.
