Product identity

The Zoro Select BULK-PF-496 is an 8 in nominal pipe size flange built to Class 300 specifications for industrial piping systems. It connects a flanged joint to a female NPT thread using A105 carbon steel with a black coated finish for corrosion resistance.

Pressure capacity and temperature headroom

The flange handles 725 psi maximum operating pressure at 72 degrees F and the same rating for steam service. Its temperature range spans 80 degrees to 780 degrees F, making it suitable for high-heat process lines while the Schedule 80 rating defines the wall thickness limit it supports.

Installation fit and system integration

The raised face design measures 15 in outside diameter with a 13 in bolt circle and twelve 7/8 in bolt holes for secure mounting. At 1 9/16 in thick and 15 in overall length, the flange mates directly to Schedule 80 pipe without additional adapters, freeing up space in compact piping layouts.

Questions about this item

Will the 13 in bolt circle diameter match the bolt pattern on my existing Schedule 80 piping?

The flange has a 13 in bolt circle diameter with 12 bolt holes sized at 7/8 in, matching standard Class 300 dimensions for 8 in nominal pipe size.

How can I verify the 725 psi pressure rating is holding after installation?

Pressurise the system to the design pressure and inspect all 12 bolt holes and the FNPT threads for leaks; the raised face and 1 9/16 in thickness are rated for 725 psi at 72 Degrees F.

Does the box include the 12 bolts and gasket needed for the 13 in bolt circle?

The package contains only the steel A105 flange with black coating; bolts, nuts and a gasket for the 12-hole pattern must be purchased separately.
