OPW Engineered Systems recently launched the new Stop-Lok Multi-Application Coupler for connecting piping and hoses used in high heat and pressure fluid-handling applications. This “evolution” of traditional unions features a compact structure with increased functionality, and no tools are required to complete the connection process, the company said.
“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,” David Jacobson, global product manager for OPW, said in a news release. “The Stop-Lok’s dual protected seals help ensure the highest level of leak protection while preventing damage from occurring to the hose or pipe during connection.”
The Stop-Lok, which is now available, is suitable for loading and unloading fluids in chemical, water, steam, hydrocarbon and heating-and-cooling applications with pressures up to 400 psi, OPW said. Ease of use is found in the Stop-Lok’s 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-in. sizes, all of which have no variation in pipe diameter, which enables it to generate consistent non-restrictive flow rates.
