Parker Seal - Spring Energized Seal - LNG Seal - is composed of a polymer material sealing shell and a corrosion-resistant stainless steel metal spring. The seal is installed in a groove, and when the spring is compressed, it creates an outward tension that forces the sealing lip to tightly adhere to the sealing groove. The spring provides elasticity to the sealing lip, compensating for wear of the sealing shell and eccentricity of mating parts, thereby forming a seal in the vacuum to low-pressure range. Additionally, system pressure assists the spring energization; the higher the pressure, the more fully the sealing lip contacts the groove, resulting in a high-pressure seal.
The sealing shell is made from PTFE, filled PTFE, PEEK, filled PEEK, PVDF, PPS, or other high-performance polymer materials through machining. The material determines that the spring energized seal can be used in a temperature range from -200℃ to +300℃, sealing almost all liquids, chemicals, and gases. It can also be stored without aging issues.
Various forms of metal springs are available to meet different sealing requirements for movement types. In some cases, O-rings made of different materials can replace metal springs as an elastomer.
Applications of Spring Energized Seals:
—— Pumps, valves, compressors
—— Pharmaceutical equipment, food equipment, medical instruments
—— Oil and fine chemical industries
—— Swivel joint manufacturing
—— Semiconductor manufacturing equipment
—— Liquid chromatography
—— Aerospace and aviation industries
U-shaped spring energized seal is a U-shaped seal that uses a metal tension spring as pre-pressure, suitable for unidirectional sealing of pistons and piston rods. The continuous action of the metal tension spring on the sealing lip ensures that there is no leakage even under zero pressure conditions. Additionally, the outstanding material characteristics of polytetrafluoroethylene ensure that there is no creep phenomenon at any speed of movement, even at very slight movement speeds. Therefore, it is suitable for sealing applications under various working media and high temperatures (250 degrees), high speeds (15 m/s), and high pressures (35 MPa), featuring low friction, no creep under zero pressure and low speed, and good dry friction performance.
