Product Name: Spring Energized Seal PTFE Rotary Shaft Seals Model NO.: U type Standard: Standard, Nonstandard Material: PTFE Shape (For Gasket): Ring Gasket Application: Junction Surface Seal, Equipment Seal, Hydroseal, Pump Seal Function: Hole Sealing, Rotary Sealing, Shaft Sealing Style: O Ring Color: White,Blue,Red,etc. Spring: Stainless Steel Place of Origin: China(Mainland) Size: Standard or Nonstandard Brand: OEM Trademark: OEM Transport Package: Bag or Carton Specification: ISO Origin: China(Mainland) HS Code: 8484100000 Product Description The Spring energized seal is a sealing device consisting of a PTFE or other polymer, energized by a corrosion resistant metal spring. When the seal is seated in the gland, the spring is under compression applying force on the gland sealing surfaces thereby creating a tight barrier to prevent gas or fluids from leaking. The spring also provides resiliency to compensate for seal wear, gland misalignment or eccentricity. While spring force provides adequate force for sealing at low pressure, at high pressure the system pressure augments the spring force to provide an even tighter seal. The PTFE Spring energized seal are precision machined from PTFE, filled PTFE and other high performance polymers.Energized PTFE Spring Seals:TypeUse forTechnicalApplicationMaterialSymmetricstandard heel groovetemperacture:-40~+260 °C ,speed ≤m/s:15,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steelrodstandard heel groovetemperacture:-40~+260 °C ,speed ≤m/s:15,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steelpistonstandard heel groovetemperacture:-40~+260 °C ,speed ≤m/s:15,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steelsymetric for rodflanged heel groovetemperacture:-40~+260 °C ,speed ≤m/s:2,pressure≤ Mpa:25virtually all fluids,chemicals and gasesPTFE-filled stainless steelhigh-low lip rodflanged heel groovetemperacture:-40~+260 °C ,speed ≤m/s:2,pressure≤ Mpa:25virtually all fluids,chemicals and gasesPTFE-filled stainless steelinsideface sealtemperacture:-40~+260 °C ,speed:static or slow rotary,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steeloutsideface sealtemperacture:-40~+260 °C ,speed:static or slow rotary,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steelOur Services1.
