It joins two male-threaded pipes or fittings in low-pressure fluid systems—such as air, water, oil, natural gas, or LPG—commonly found on heavy-duty trucks, trailers, and industrial equipment. Replacement is typically required when the coupling cracks, corrodes, or leaks, compromising the seal. This coupling is rated for 1200 psi working pressure and a temperature range of -65°F to 250°F.
