Hard coat aluminum fittings are lightweight, which makes them easy to handle, yet they’re strong enough to stand up to the toughest conditions. PT Coupling’s fittings are resistant to corrosion and pitting caused by chemicals, which makes them an excellent choice for petroleum products, gasoline, hydraulic oil, acids and coolants. With a hardened coating, these fittings are also ideal for abrasives such as sand and salt water. Engineered to exceed industry standard pressure ratings, these fittings will handle operating pressures ranging between 50 and 250 PSI. The cam arms are fitted with solid pins to reduce the chances of failure, and fittings come standard with Buna gaskets to prevent leaks. All standard couplers are designed so that you can retrofit them with STA LOK II locking mechanisms — you won’t need to stock separate coupler bodies should you decide to switch between locking systems.
The STA LOK cam arms are a positive locking cam and groove system, while STA LOK II cam arms are a passive locking system. Both STA LOK and STA LOK II were originally designed for use by the United States Coast Guard. Today, you can find these fittings in a variety of facilities, including those that manufacture food and beverages, drugs, petroleum, chemicals, grout and cement. Hard coat aluminum fittings are also widely used for water treatment and transport, waste removal and fuel delivery. You’ll find these fittings in industries such as mining, industrial manufacturing facilities, construction, chemical manufacturing, government contracting, marine and aviation.
The hard coat aluminum fittings offered by Commercial Industrial Supply are manufactured by PT Coupling, a supplier of industrial hose fittings. Founded in 1951, PT Coupling is based in Enid, Oklahoma. All fittings are made in the USA using high-quality raw materials. Casting is done in American foundries, and the fittings are machined by PT Coupling’s Central Machine & Tool facility. To ensure quality and uniformity across all of their products, PT Coupling maintains International Organization for Standardization (ISO) 9001 certification.
