Garlock 3760 Multi-Swell Gaskets

Garlock MULTI-SWELL™ Style 3760 is a controlled-swell gasketing material designed to generate its own compressive load when exposed to oil, water, and a variety of other fluids. Certified to NSF/ANSI/CAN 61 & 372 for potable water service, this material is ideal for lower-load flanges often used with compressors, gearbox assemblies, pumps, and lightweight oil systems. Gaskets made of MULTI-SWELL™ deliver an ultra-tight seal where traditional fiber or rubber gaskets leak or crush over time. With superior conformability, it easily replaces traditional vegetable fiber materials that wick process fluids and weep over time, offering a more reliable and longer-lasting seal across a wide range of general service applications.

The proprietary formulation of MULTI-SWELL™ 3760 is highly effective for sealing flanges that are worn, irregular, or lightweight in design. The improved compressibility over traditional fiber gasket materials forms an effective seal in less-than-perfect surfaces. Recognized in the Plastic Pipe Institute’s TN-38 technical bulletin as a preferred solution for sealing HDPE flanges, it delivers exceptional performance in demanding polyethylene flange connections. Easy to cut and handle during fabrication, extremely forgiving during installation, and proven reliability ensure MULTI-SWELL™ 3760 delivers safe, effective sealing across a wide range of industries and demanding service conditions.
