Engineered to safely contain and control fluid at working pressures up to 30,000 PSI, this quick disconnect (QD) coupler is an essential asset for high-pressure test benches, hydrostatic pump units, and heavy-duty tensioning equipment.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eThis specific coupler features a Type M9 (9\/16\" Type M) female connection profile designed for seamless, push\/pull quick-disconnect operation. The back of the coupler utilizes a standard M9 connection for reliable integration into 9\/16\" Type M high-pressure hose assemblies and tubing configurations.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eCrucially, this model is equipped with a high-performance \u003cb data-path-to-node=\"6\" data-index-in-node=\"58\"\u003eIntegrated Check Valve\u003c\/b\u003e. This built-in safety feature automatically shuts off fluid flow the instant the coupler is disconnected. This prevents hazardous high-pressure blowback, minimizes fluid loss, and maintains system pressure integrity on the supply side, allowing operators to safely and cleanly swap lines or tools without completely depressurizing the main source.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
