Gland Seals (GS)

MFP Seals’ GS Seal is a modern day, heavy-duty gland seal, used for enhanced performance, in place of an O-Ring or O-Ring and Back-Up Ring combination, used to seal threaded glands in Mobile Hydraulic cylinders. The GS provides a high dynamic, pressure energized sealing effect, with 4 sealing contact points that increase in radial force as pressures increase. The GS is primarily designed for heavy-duty, static sealing applications. Its unique design resists the extrusion and pressure damage that normally occurs with O-Ring gland seals. Typically made from our U2150 Ultraflex® Urethane, it is easy to install the GS seal over threaded glands without damage to the seal and provides excellent rebound resilience, hydrolysis and abrasion resistance.
