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 is available in material NBR, HNBR, FKM with 2 integral anti-extrusion springs.
