This coupler requires no tools to seal
The new Stop-Lok Multi-Application Coupler (photo) is used for connecting piping and hoses that are used in higher heat and pressure fluid-handling applications. This evolution of traditional union couplings features a compact structure with increased functionality. No tools are 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 (27.5 bars). 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. The Stop-Lok’s smooth-bore coupler is constructed of 316 stainless steel and is available in¾-, 1-, 1½-, 2- and 3-in. sizes, all of which have no variation in pipe diameter, which enables it to generate consistent non-restrictive flowrates.
