HNBR S seal for downhole application 


Wellhead is a key component of oil and gas infrastructure. Wellhead sealing materials need to withstand high pressure and high temperature.


S Seals are well suited for sealing wellheads, connectors, downhole tools, high pressure valves and other demanding oil and gas applications. The non-extrusion springs can be fabricated from different metals.

The S seal is made of spring and rubber material could be NBR, HNBR, FKM ect.


S-seal is a compact one-piece seal design with anti extrusion elastomer with two molded anti extrusion springs at the outer edge. Its unique design integrates two non extrusion devices and a sealing element into an overall structure to provide two-way sealing. At the same time, combined with a simple symmetrical contour non extrusion device, headless coil springs are used on both sides of the seal, allowing a large extrusion gap to be bridged under high pressure. Non extruded equipment (when made of the following materials) limits metal seals to static applications. S seal is a preferred design which attack by oilfield media where an O ring cannot survive the maintenance-free life cycle of the equipment.


Product Highlights:

1. Alternative engineered seal design to using T Seals or O-Rings, traditional S Seals utilize metal spring for supporting sealing of various extrusion gaps.
2. Designed as an engineered replacement for T Seals and O-Rings.
3. One piece design for easier installation into glands vs. multiple component seals.
