Garlock's PS-Seal: A GYLON® Powered High-Performance Seal for Rotating Shafts

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.

These 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 the PS-SEAL® Standard single lip as well as a wide range of other configurations.

The high performance PS-SEAL® works with a sealing lip made of GYLON® or other modified PTFE. Garlock produces GYLON® using a proprietary process.

In short, the PS-SEAL® Standard is a Garlock shaft seal consisting of a stainless steel (1.4571) case, a GYLON Black seal lip and a static sealing element made of FKM.
