Zoro Select Aluminum Blind Flange 9 in

This aluminum blind flange terminates a 4 in nominal pipe system with a flat face. It suits maintenance crews and plant engineers who need a reliable blanking plate for Schedule 40 piping rated to Class 125.

Capacity and headroom: 125 psi at 72 °F

The flange handles 125 psi maximum operating pressure at 72 °F and up to 185 psi for steam service across a 0 °F to 270 °F range. It runs out beyond those pressure or temperature limits and is not suited for higher-class flanges or larger nominal sizes.

Six 6063 alloy and eight 3/4 in bolt holes

The 6063 aluminum construction resists corrosion while keeping weight low for handling. Eight bolt holes on a 7 1/2 in bolt circle accept 3/4 in fasteners so the joint assembles with standard hardware without special tooling.

Questions about this item

Will the 9 in outside diameter and 7 1/2 in bolt circle match my existing Schedule 40 piping?

Yes, the flange is built for Schedule 40 pipe with a 9 in outside diameter and a 7 1/2 in bolt circle, so it aligns with standard Class 125 drilling.

How can I verify the seal is holding at the rated 125 psi operating pressure?

Pressurise the system to the working pressure and inspect the gasket face and all eight bolt holes for leaks; the flat face and 15/16 in thickness are designed to maintain a tight seal at 125 psi.

Does the box include bolts, nuts or a gasket for the eight 3/4 in bolt holes?

The flange ships as a single 6063 aluminum blind piece; bolts, nuts and a compatible full-face gasket must be purchased separately.
