Seal stack for well tools sliding sleeve
In oil and gas well completions and workovers, controlling fluid communication between the tubing and annulus is critical. Our Seal Stack for Well Tools Sliding Sleeve is a high-performance sealing assembly designed specifically for this purpose. Built with premium materials and precision engineering, it withstands extreme downhole conditions (4 °C to 177 °C and up to 15,000 psi). Proven in over 2,400 reciprocating test cycles, this seal stack delivers long-term durability and leak-free service. Its robust design ensures reliable, precise fluid control and improved operational efficiency in demanding field environments
Key Applications
FLS and FLS-R Gate Valves: Optimizes sealing in critical flow-control valves. By acting as a flow restrictor, the seal stack protects primary seals from high-pressure surges, enhancing safety and integrity in gate valve operations
Sliding Sleeves: Ideal for infinitely adjustable downhole sleeves. The dynamic V-packing design maintains a tight seal between the sleeve and ports during opening/closing, preventing fluid leaks under high pressure and flow
Bi-Directional Piston/Rod Seals: Engineered for double-acting tools. Its bi-directional pressure-bearing capability handles alternating pressures reliably, ensuring stable sealing in pistons and reciprocating rod systems
