MULTI-SWELL™ Style 3760 Controlled Swell Material

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.

The only controlled-swell gasket material engineered to create its own compressive load for a superior seal in challenging oil, water, and low-load applications.

Garlock MULTI-SWELL Style 3760 is a controlled-swell gasketing material designed to generate its own compressive load when exposed to oil, water, glycol solutions, 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.

MULTI-SWELL Style 3760 Gasket Sheet Material

Easy to cut and handle during fabrication, MULTI-SWELL replaces outdated vegetable fiber materials that wick process fluids and weep over time, which creates leaks and reduces facility cleanliness. This highly compressible material conforms to uneven or worn flange surfaces, and maintains structural integrity when exposed to petroleum oils, diesel fuel, kerosene, and water.

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.

MULTI-SWELL Style 3760 Fabricated Gaskets

The proprietary formulation of MULTI-SWELL 3760 swells in contact with oil or water to create its own compressive load for a tighter seal. Recognized by the Plastic Pipe Institute’s TN-38 technical bulletin as a preferred solution for sealing HDPE flanges, MULTI-SWELL gaskets seal effectively at lower loads than traditional fiber gaskets, making it ideal for lightweight and low-torque flange applications.
