These iron chrome plated C-type quick disconnect air hose fittings are built for mechanics, woodworkers, and workshop operators who run pneumatic tools daily and can't afford downtime from unreliable couplings.\u003c\/p\u003e\n\u003cp\u003eEach fitting is machined from iron with a chrome plated finish for corrosion resistance and a smooth sealing surface. Available in both plug (P-series: PF, PH, PM, PP) and socket (S-series: SF, SH, SM, SP) configurations, with size codes 20, 30, and 40 corresponding to nominal port diameters of approximately 1\/4\" (6.5 mm), 3\/8\" (9.5 mm), and 1\/2\" (12.7 mm) respectively. Sold in packs of 1, 3, or 5 pieces.\u003c\/p\u003e\n\u003cp\u003eTypical applications include connecting air compressors to impact wrenches and spray guns in auto body shops, routing pneumatic lines to nail guns and sanders in carpentry workshops, and building modular compressed air distribution systems in garages or light industrial settings where quick tool changes are routine.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for standard C-type (industrial interchange) pneumatic systems.
