Ultrapure Water Systems (UPW) / STRESS SAVER^® 3522 & STRESS SAVER^® 370

As a microelectronics manufacturer, eliminating contamination risks in the water and fabrication process is critical to ensure long-term reliability and desired system efficiencies. Ideal for ultrapure water systems, Garlock’s 100% pure PTFE STRESS SAVER^® 3522 and the PTFE encapsulated EPDM STRESS SAVER^® 370 can reduce those cross- contamination risks associated with traditional flange gaskets. The STRESS SAVER^® 3522 and STRESS SAVER^® 370 gaskets feature molded-in stress concentrators that significantly reduce the contact surface area, thus allowing for low load and reliable sealing, even in less-than-perfect flange connections. Special high-purity packaging and handling options are also available if specified.

Chemical Exhaust Tool Hook-Up / GYLON^® Style 3545 Gasket

Etching, coating, cleaning, drying, and vaporization processes produce chemical-laden vapors that must be actively evacuated from tooling chambers to avoid contamination. These conditions require a chemical exhaust system with leak-free integrity. Garlock’s GYLON^® 3545 utilizes a very conformable microcellular PTFE body with a rigid PTFE center layer, offering up to 70% compressibility, universal chemical compatibility, and a tight, reliable seal to prevent leaks in your chemical exhaust systems.

Hydronics - Central Hot and Cold Water / MULTI-SWELL^® Style 3760 Gaskets

Garlock MULTI-SWELL^® Style 3760 and 3760-U (NSF-61 approved for potable water systems) are manufactured from synthetic fibers and proprietary fillers to help obtain a tight seal, supporting water conservation efforts in central hot and cold-water systems as well as other industrial sealing applications. The unique formulation is designed to react with targeted media such as oil and water, offering a controlled swell technology. Controlled swell helps to combat relaxation in the flange assembly and provides sealing integrity over time. Twice as compressible as standard fiber gaskets, MULTI-SWELL^® also offers forgiveness in irregular or less-than-perfect flange conditions, making installation much more forgiving.
