Loading and coupling systems specialist, OPW Engineered Systems has announce the launch of its new Stop-Lok multi-application coupler for use in connecting piping and hoses that are used in higher heat and pressure fluid-handling applications. This evolution of traditional union features a compact structure with increased functionality, with no tools required to complete the connection process.

The Stop-Lok is suitable for loading and unloading fluids in chemical, water, steam, hydrocarbon and heating-and-cooling applications with pressures up to 400 psi. The Stop Lok has a scalloped connection sleeve that allows for a hand-tight, tool-free connection that cannot be over-tightened, which lets the user know that ‘when it stops, it’s locked’. The Stop-Lok’s smooth-bore coupler is constructed of 316 stainless steel and is available in 3/4, 1, 1-1/2, 2 and 3 inch sizes, all of which have no variation in pipe diameter, which enables it to generate consistent non-restrictive flow rates.

David Jacobson, global product manager for OPW Engineered Systems, says: ‘Union fittings have been used for decades as a quick, easy-to-assemble connection point between a pipe and hose, but our new Stop-Lok coupler offers advanced features that enable it to deliver even better efficiency. The Stop-Lok’s dual protected seals helps ensure the highest level of leak protection while preventing damage from occurring to the hose or pipe during connection.’
