The PS-SEAL® product line stands for reliable sealing of rotating shafts at high circumferential speed, high pressure and extreme temperatures. Abrasive media is sealed as well as aggressive media. Radial shaft seals typically do not perform well under these conditions as their seal lips are made of elastomeric materials. PS-SEALs are used in many different applications and can also be an alternative to mechanical seals and braided packings. The product line PS-SEAL® offers cost-effective and practical solutions to a wide range of applications. The portfolio of Garlock shaft seals offers standardized as well as special customized seals. The high performance seals PS-SEAL® work with a sealing lip made of GYLON® or other modified PTFEs. Garlock produces GYLON® in a process that has been specially developed.
