Product Details

Spring energized seals are a highly reliable option when standard elastomer-based and polyurethane based seals will not meet the operating limits, equipment parameters, or environmental conditions of your application. Even when a standard seal might meet basic needs, many engineers turn to spring energized seals for an added level of reliability and peace of mind.

Spring energized Seal, designed and produced by Xlong Seal,is a special high-performance seal with spring built-in. With suitable spring force and system fluid pressure, the sealing lip (surface) is gently pressed to the sealed metal surface to get a very excellent sealing effect.

Effect actuation of the spring can overcome the slight eccentric of metal surface and wear of the sealing lip,while continuing maintain the desired sealing performance. PTFE is with excellent heat resistance, and better chemical resistance than FFKM. It can be applied in virtually all chemical fluids, solvent, hydraulic fluids, lubricants.

Its low compression set contributes to its long-term sealing performance The use of special springs overcomes the problem of PTFE and other high performance plastics flexibility shortage.
