It combines the soap injection, thermal relief, unloader and valve ports into a single, corrosion-resistant unit so you can return your washer to service quickly. The manifold is sold as a kit including valves, unloader, thermal relief valve (TRV), soap injection unit, garden-hose inlet and M22 high-pressure outlet plus mounting hardware.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this manifold fit my pressure washer pump?\u003c\/h3\u003e\n\u003cp\u003eThe HRepair 7108366 is engineered to match the OEM mounting pattern and port layout of Technologies models 510020 and 520006 and Simpson 7108366 pumps. The single-piece design keeps alignment and sealing consistent to avoid leaks or rework during installation.
