Product Detail

Casing head and tubing hanger FS seal

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. 

FS-seals are used against rough surface finish and wider dimensional and geometrical tolerances of casing and tubing. 

Sealing materials utilized for wellheads need to withstand pressures as high as 15 000 psi,  and temperature from –46°C to +177°C (–20°F to +350°F).

JST has toolings for standard sizes from 4-1/2" to 30". FS-seal material include NBR, HNBR, FKM with 2 integral anti-extrusion springs.

FS seal is a custom designed spring energized elastomer seal, which combines the advantages of the overall support assembly and the flexibility of elastomer seal, and can provide the maximum extrusion resistance in the demanding high-pressure sealing environment. FS seal is ideal for many chemical processing, chemical transportation and oil and gas applications, such as oilfield casing and tubing.
