Zoro Select Aluminum Flange 5 in

This Zoro Select flange is a flat, threaded pipe fitting made from 6063 aluminum. It suits plumbing and industrial assemblies that require a 1 1/2 inch nominal pipe size with a Class 125 rating. The component arrives new and ready for installation.

Pressure Rating and Temperature Range

The flange handles 125 psi at 72 degrees F and a maximum steam pressure of 185 psi. Its operating window spans 0 to 270 degrees F, so it covers typical water and low-pressure steam lines. Schedule 40 pipe matches the design, while higher-pressure or cryogenic duties fall outside the rating.

Threaded Connection and Bolt Pattern

A female NPT thread on the flanged end mates with standard Schedule 40 pipe, and four bolt holes on a 3 7/8 inch circle accept 5/8 inch fasteners. The 5 inch outside diameter and 11/16 inch thickness fit the stated bolt pattern without needing extra spacers. Builds requiring a different bolt circle or flange class will need another part.

Questions about this item

Will the 5 in aluminum flange mate with my existing Schedule 40 pipe and 3 7/8 in bolt circle?

Yes — it is built for Schedule 40 pipe, has a 5 in outside diameter and a 3 7/8 in bolt-circle with four 5/8 in bolt holes.

How can I verify the flange is sealing correctly once installed?

Pressurise the line up to 125 psi at 72 °F or 185 psi steam pressure and check for leaks at the threaded joint and bolted face.

Does the box include bolts, gaskets or thread sealant, or must I buy them separately?

Only the aluminum flange is supplied; bolts, gaskets and sealant are not included and must be sourced separately.
