Industrial W43-16-16U 1 NPT 4 Bolt Pump Flange Pad

Anchor Fluid Power W43-16-16U is a SAE Code 61, 4-bolt flange pad with a 1-inch NPTF port and a 1-inch pad size, designed to accept a compact, high‑pressure connection in hydraulic systems. This carbon steel kit includes the flange, four hex bolts with lockwashers, and a Buna-N O-ring, delivering a ready-to-install assembly for reliable sealing at the interface between a pipe or hose and a Code 61 flange. The pad is rated for up to 5700 psi maximum working pressure, making it suitable for demanding hydraulic circuits where space is limited and a secure, leak‑free seal is essential. The flange’s O-ring groove interface supports a robust seal in conjunction with the supplied O-ring, while the standard four-bolt pattern aligns with common SAE 4‑bolt configurations for straightforward mounting. Typical applications include high‑pressure hydraulic power units, cylinders, and line adapters where a 1-inch connection must transition to a fixed flange, preserving flow with a compact form factor and dependable seal integrity.
