In the demanding world of oilfield downhole operations, reliability under pressure is paramount. The V-Stack seal assembly emerges as a critical component in valves, fracturing systems, and other high-stakes equipment. Engineered to excel in medium to heavy-duty applications, Chevron Vee Packings deliver unmatched performance in extreme temperatures, pressures, and even misaligned sealing gaps.

Due to its special design, the V-Stack seal assembly is very sensitive to the change of fluid pressure, so that it can deflect in the whole radial part, so as to increase the sealing load and effectiveness according to the proportion of applied pressure. In the assembly, the energized axial force is transmitted between each packing ring, so that each packing ring forms positive contact with the surface of the mating hardware. Special material grades are suitable for various working conditions.

Crafted from advanced materials like PEEK and modified PTFE, V-Stack seals combine elasticity, chemical resistance, and extrusion durability. These materials are tailored to withstand aggressive wellbore fluids, high-temperature cycles, and abrasive particulates. Whether sealing sour gas valves or high-pressure fracturing pumps, the Vee Packings’ adaptability ensures longevity in diverse operating conditions.

V-packing sets feature a modular design with a top/bottom component and adjustable center vees. This flexibility allows operators to optimize the assembly by altering material grades or stacking configurations to suit specific pressures, temperatures, or chemical exposures. For instance, modified PTFE excels in corrosive environments, while PEEK offers superior thermal stability for high-heat applications.

Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
