PTFE guide and wear strip

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.

Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.

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.

The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions. The chevron seal stack material could be PEEK, modified PTFE and spring.

The JST valve insert seal is mainly used for sealing valve seat of fracturing pump. It is made of modified polyurethane material of excellent extrusion resistance, puncture resistance and fatigue resistance, which guarantees the fracturing work under various working conditions.

Swivel joint ball plug is working together with hammer union seals, to seal the balls of high pressure elbows and grease.

High pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure.

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