Description

SAE Code 61 Hydraulic Flange x Butt Weld Pipe – 2-1/2" x 2-1/2" Schedule 40

This SAE Code 61 Flange x Butt Weld Pipe Adaptor provides a connection between a 2-1/2" SAE Code 61 four-bolt hydraulic flange interface and 2-1/2" Schedule 40 steel pipework.

Manufactured in a one-piece configuration, the adaptor features a flat-face flange with an O-ring seal and mounting clearance holes, allowing it to be bolted to a compatible SAE Code 61 flange connection while the opposite end is butt welded into a hydraulic piping system.

Designed for industrial hydraulic pipework, hydraulic power units and fixed hydraulic installations where a flanged connection is required.

Installation Information

This fitting is intended for permanent installation into compatible Schedule 40 steel pipework using an appropriate butt welding procedure.

The flange connection must be assembled using suitable SAE Code 61 mating components, fasteners and sealing arrangements.

Important: SAE Code 61 flange dimensions do not automatically establish the working pressure rating of the completed piping system. The allowable operating pressure must be determined from the flange, pipe, welds, seals and associated components.

Installation and welding should be carried out by suitably qualified personnel.

Ordering Information

Supplied as one 2-1/2" SAE Code 61 x 2-1/2" Schedule 40 butt weld flange adaptor.
