The brass seal is used as the mating surface for a claw coupling with a rubber seal and prevents two elastomeric sealing surfaces from sticking together. This makes the coupling particularly easy to disconnect and reconnect.\u003c\/p\u003e\u003cp\u003eThe coupling is made of galvanized malleable cast iron and, in addition to the brass seal, features an oil-resistant hose ring and a galvanized retaining screw. A matching claw coupling with a rubber seal is used as the mating coupling.
