Garlock’s Style 204 Expansion Joint with an EPDM tube offers high versatility and maximum resistance to water absorption, chemical, and acidic media. EPDM is an outstanding solution when abrasion and mild heat aging are a concern. This versatile option is an excellent upgrade from standard Chlorobutyl and a great choice for challenging mixed media applications.

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.

Consider upgrading to a GUARDIAN® FEP, ABRA-SHIELD ®, or ABRA-LINE™ tube for added protection.

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.

Retaining rings are required with our expansion joints. Click here to view available sizes. Products with an inside diameter of 38 inches and above will require additional packaging charges.

Consider upgrading to our P2000 style expansion joint, which offers increased performance and comparable pricing. Click here to view available sizes.
