Aluminum camlock couplings or aluminium cam & groove couplings are an economical and durable option for quick connect/disconnect coupling for PVC suction hoses, industrial hoses and PVC layflat hoses used in agricultural irrigation, water transfer of construction and industries, and chemical & petroleum delivery. Its working temperature ranges from -150°F to +250°F (-101°C to 121°C) and working pressure doesn't surpass 250 psi at ambient temperature. Aluminum camlock fittings come in a variety of sizes ranging from 1/2" to 8" according to MIL-C-27487/ISO A-A-59326. 1/2" through 4" and 6" parts are interchangeable, while 5" and 8" through 12" are not interchangeable for no standards are established for these specifications. Our aluminium quick connect/disconnect couplings are manufactured by gravity casting. Thanks to its good abrasion resistant, light weight and economical cost, aluminium cam & groove fittings are used with water, hydraulic oil, coolants, gasoline & petroleum products.
