Piston. These pistons come equipped with Belleville Shim Stack, designed for precision and ease of use. This innovative component allows you to adjust the output pressure of your regulator quickly and efficiently without needing to purchase an entirely new regulator unit. Simply pull out the entire shim stack unit and drop it into your regulator for seamless performance.\u003c\/p\u003e\n\u003cp\u003eThe shim stack wraps around a robust brass piston equipped with all necessary O-rings, ensuring a leak-free experience. This piston stack is also an excellent solution for those dealing with a worn-out piston system that no longer provides consistent output pressure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMid Pressure Output:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eThis piston shim stack is preset to make the regulator output pressure 450-550psi.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelleville Shim Stack:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBelleville Shims (or disc springs) can provide a significant amount of force in a compact space.
