Rated for a Cold Working Pressure (CWP) of 15,000 PSI, this piston serves as the dynamic sealing interface between the high-pressure wellbore fluids and the atmospheric side of the valve. It is a vital part for adjustable choke valves used in high-pressure well testing, frac flowback, and manifold operations.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eManufactured from high-grade forged stainless steel or premium alloy steel, the seal piston is machined to exacting tolerances and features a polished, low-friction surface finish. It is designed to house a stack of high-performance seals, including O-rings and backup rings, which prevent hazardous leaks along the stem. The robust construction ensures that the piston can withstand the intense mechanical stresses, high-velocity pulsations, and abrasive environments typical of 15M pressure systems without deforming or losing its sealing capability.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eAs a high-wear component, the 3\" 1502 Seal Piston is essential for comprehensive choke maintenance. Replacing a worn or pitted piston during a bonnet rebuild restores factory-level sealing performance, ensuring precise flow regulation and maximum operator safety on the job site.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
