High Pressure Spring Energized Seal Piston Rod Seal 

High Pressure Spring Energized Seal Piston Rod Seal Helical Spring Seals are comprised of a wound ribbon metal spring installed in a polymer jacket. This helical shape spring affords a relatively high load versus deflection range resulting in a seal product that can provide very tight sealing. Spring energized PTFE seals perform reliably in a variety of applications where conventional elastomeric seals fail due to chemical attack, extreme heat or cold, friction, extrusion or compression set. PTFE seals have three basic design elements: A pressure-actuated U-shaped jacket A metal spring loading device High performance polymeric seal materials Sample: Freely Business type: Manufacturer Delivery time: 10~15days
