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.
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.
EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals.
A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.
BT Seal is a static seal that is used to seal rough casing and tubing. It is constructed from an elastomer with anti-extrusion spring bonded within it. Springs are available in stainless steel, elastomer could be HNBR or NBR.
A glass filled nylon wear ring, also called wear band, offers high bearing load capacity over a broad range of temperatures.
The FHB seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange internal face seal.
