FS Seals

Features

• Similar in form and function to a rod orientation Spring Seal, the FS seal is a double acting static seal designed for use as casing and tubing hanger seals in wellheads
• FS seals are designed for use against rough casing, with wide dimensional and geometrical tolerances and variable surface finishes, which can result in large clearance between the mating parts of the wellhead
• An FS seal typically has a larger cross section than a Spring Seal to increase the sealing force on the casing while the recess in the seal back controls the radial compression on the seal by allowing it to deflect when in contact with a larger or out-of-round casing section
• The FS seal is made up of an elastomeric sealing element with molded-in springs to act as anti-extrusion elements
