Industrial W4-48-48U Socket Weld Flange 3 Inch

Anchor Fluid Power W4-48-48U is a 3-inch Code 61 flat socket weld flange, crafted in carbon steel with a four-bolt pattern for robust, repeatable assemblies in hydraulic piping. The W4 designation indicates a four-bolt flange, while the 48-48 sizing denotes a 3.00-inch pad size and 3.00-inch pipe compatibility, and the trailing U suffix signals that mounting hardware and an O-ring groove are included with the flange. This Code 61 flat socket weld flange is rated for service in hydraulic systems and typically pairs with an O-ring seal for a leak-resistant socket-weld connection, with bolts and O-rings supplied for a ready-to-install kit. In practical terms, it serves well in high-pressure hydraulic circuits where a compact, gasketed interface between pipe and flange is required, delivering a dependable 3-inch connection with a groove-ready O-ring feature for enhanced sealing reliability.
