Garlock’s Style 204 Expansion Joint with a Nitrile tube offers rugged construction paired with premium materials to prevent internal attack from oil, fuel, and media containing hydrocarbons. Our high-purity Nitrile is formulated and processed by Garlock’s internal elastomer experts for superior strength and leak protection.

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 an HNBR tube for added hydrocarbon 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.
