Garlock’s Style 204 Expansion Joint with a GUARDIAN® FEP tube offers first-in-class chemical resistance paired with a proprietary mechanically bonded tube, creating the sealing industry’s strongest, safest expansion joint. Chosen and trusted when safety and reliability are paramount, this uniquely engineered sealing solution remains in service long after most competitor’s glued in liners have separated.

Style 204 spool-type non-metallic piping expansion joints are manufactured with the industry standard narrow arch design, intended for use in dynamic conditions where both pressure and vacuum concerns are present. Utilize Garlock styles 204HP, 204EPS, and 204MAX Expansion Joints for extreme pressure requirements.

The Guardian® FEP tube liner offers unmatched aggressive chemical resistance and is mechanically bonded to the rubber expansion joint, making it impervious to delamination, and reducing the occurrence of leaks and unscheduled emergency maintenance. FDA Compliant to 21CFR 177.1550.

Style 204 is available in the following cover material options to protect the exterior of your expansion joint: Chlorobutyl for general service, EPDM and Fluoroelastomer for UV, ozone, water impermeability and temperatures up to 300°F and 400°F, respectively. Neoprene is an excellent choice for marine use, while utility grade Nitrile is perfect for oily environments.

For added durability, all Garlock expansion joints are painted with a proprietary blue protective coating.
