50Spring energized PTFE lip seal
Spring energized seal is a spring-energized U-cup that uses a variety of jacket profiles, spring types and materials in rod and piston, face and rotary seal configurations. They are used when elastomeric seals fail to meet temperature range, chemical resistance or friction requirements.
Spring loaded seal consists of variety of jacket profiles and spring types. Spring energized seals can achieve the sealing effect compensation under different pressure conditions by spring energizer. The spring energizes the seal and supplies all of the load needed for sealing when the media pressure is too low to fully actuate the lips.

The seal jacket of adhesive dispenser/dispensing seal is made of ultra-high molecular UHMWPE or PEEK, with installed stainless steel anti-corrosion spring with low temperature resistance treatment.
The spring energized seal is widely used in medical equipment, which is generally composed of a corrosion resistant spring and a seal ring made of U-shaped filled PTFE/UPE material.
JST FHR series is made of a helical wound spring and a polymer jacket, which is mainly used for rod.
LNG Lip Seal For Filling Guns is commonly used in LNG (liquefied natural gas) filling guns.
Dovetail groove is used to put the O-ring or elastomer dovetail seal during installation. This groove is not common because it is more expensive to machine, but this dovetail groove can avoid seal extrusion out.
Pumpdown plugs separate cement from the displacement fluid during liner cementing operations.
Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. It has high mechanical properties, good oil resistance, low water absorption and high wear resistance.
Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.
