Product identity

The Zoro Select BULK-FG-1172 is a full-face PTFE flange gasket manufactured for 2-1/2 inch pipe and ANSI Class 150 flanges. It suits maintenance crews and plant engineers who need a chemically inert seal in corrosive or high-purity piping systems.

Temperature envelope

PTFE construction allows continuous service from minus 450 degrees F up to 500 degrees F without degradation. The material carries a California Proposition 65 notice for a chemical known to cause reproductive harm, so handling procedures must follow site safety plans.

Installation notes

The gasket measures 7 inches outside diameter, 2 7/8 inches inside diameter and 1/8 inch thick with four 3/4 inch bolt holes. Alignment is straightforward on matching flanges, but over-tightening bolts can cold-flow the PTFE and create leak paths. No fasteners are included.

Questions about this item

Should I choose the full-face PTFE gasket for 2-1/2" pipe or a different size?

Select the gasket that matches your pipe size exactly; this model fits 2-1/2 inch pipe with a 2 7/8 inch inside diameter and 7 inch outside diameter.

What does the 500 Degrees F maximum temperature mean for my application?

The gasket withstands continuous heat up to 500 Degrees F, so it suits high-temperature steam or chemical lines without degrading.

How does the ANSI Class 150 rating limit the pressure I can use?

ANSI Class 150 flanges cap the working pressure at the class limit, so this gasket is intended for systems rated to that pressure class.
