From the Selection Guide below, choose an appropriate coupling based on the hose type and application working pressure. Additional information is available on the Coupling Selection Guide PDF .

NOTE: The data below is based on years of hydrostatic testing. All tests are performed to the ASTM D380 standard. We employ a safety factor based on the Rubber Manufacturers Association (RMA) recommendations of 4x working pressure (WP) for most hoses with the exception of 3x for water up to 150 psi., 5x for LP gas and 10x for steam. This means that any hose with a 4x safety factor is tested to 4000 psi., or beyond, in order to establish a 1000 psi. rating. 

*Domestic Suction Coupling
**Ball & Socket pressure ratings are based on 1.5x WP
