Built mainly from brass for corrosion resistance, the set includes both high and low pressure couplers, replacement valve cores for common refrigerants, and O-rings to restore a tight seal after maintenance. The quarter-turn side ball valve and integrated O-rings reduce the chance of accidental leaks during core removal, letting you work more efficiently and safely.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit prevent refrigerant from escaping during service?\u003c\/h3\u003e\n\u003cp\u003eThe couplers feature a side-mounted ball valve that opens and closes with a simple quarter-turn, isolating the system while you remove or install valve cores.
