Extension nipples, couplings, unions
MINCO Bayonet Extensions are best for moderate temperatures and pressures.
Extensions in assemblies serve to isolate connection heads from process connections in order to clear pipe insulation or limit heat conduction into the head. Choose from galvanized or stainless steel nipples, couplings, and unions. Nipples are short lengths of pipe to extend connection heads away from processes. Couplings and unions have two 1/2 -14 NPT female threads to join nipples to other fittings. Unions allow installation without rotating the connection head.
