Well completion liner wiper plug

Wellhead secondary pack off seal is used to seal the hanger to the wellhead.

The FS-seal is a relatively large cross section spring energized elastomer casing and tubing hanger seal for wellheads that always has the springs on the internal surface.

BS seal is rod seal for hydraulic cylinders, single-acting, polyurethane u-cup design with secondary sealing lip.

ODU Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

The spring energized seal is a high-performance Teflon seal with a special spring inside.

EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals.

JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be  PEEK, modified PTFE.

Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.
