Spring energized face seals are often used in static sealing applications. PTFE face seals offer advantages over traditional O-rings in terms of pressure handling, chemical compatibility, and operating temperature range. Often used in cryogenic applications. Face seals are designed for either internal or external pressure, but not both. Product Type Product Description Technical Data Working temp ...

PEEK (polyetheretherketone) and PTFE (polytetrafluoroethylene, commonly known as Teflon) backup rings both play important roles in sealing applications, but they have some significant differences in material properties and application benefits. Here are their differences and their respective advantages:     1. Differences in material properties PEEK backup rings: Strength and rigidity: P...

In cryogenic systems, where extreme temperatures, high vacuum, and high pressure create challenging operating conditions, achieving reliable sealing is critical. PTFE Spring Energized Seals are specifically designed to meet these demands. Combining spring with a polymer jacket, these seals provide exceptional performance in cryogenic environments, ensuring leak-free operation and long-term reliabi...

Hydraulic systems demand precision sealing under extreme pressure, temperature shifts, and contamination. Standard rubber seals often fail through extrusion, swelling, or wear—leading to costly leaks and downtime. The SPGW seal is specially designed for heavy hydraulic equipment and includes a Teflon mixture outer ring, a rubber inner ring and two POM backup rings. The rubber elastic ring provides...

In oil wellhead applications, sealing system failures are not an option. Environments characterized by extreme pressures (often exceeding 15,000 psi), aggressive sour gas (H₂S/CO₂), rapid temperature fluctuations, and constant vibration relentlessly test the limits of standard sealing solutions. Elastomeric seals can extrude, degrade, or harden, leading to catastrophic leaks, environmental hazards...

1. Application ScenariosPTFE (Polytetrafluoroethylene) wear rings, also known as guide rings, are primarily used in hydraulic cylinders and pistons to: Provide Guidance: Center the piston rod within the cylinder barrel and the piston within the tube, preventing metal-to-metal contact and misalignment. Absorb Radial Loads: Handle side loads and transverse forces exerted on the p...
