The FHB seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange internal face seal.
Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.
Swivel joint ball plug is working together with hammer union seals, to seal the balls of high pressure elbows and grease.
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.
KZT is used in combination with anti-wear and piston ring to prevent cylinder oil from mixing with foreign particles, avoiding seal damage.
Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).
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.
