Value Collection 31946734 Flange Gasket 3 Inch Pipe

Product Description

The VALUE COLLECTION 31946734 is an aramid fiber fiberglass flange gasket engineered for 3-inch nominal pipe service. It measures 3-1/2 inches inside diameter and 5-3/8 inches outside diameter, with a compressed thickness of 1/16 inch. The gasket is rated to 1,450 psi maximum working pressure and withstands temperatures up to 750 degrees F, making it well suited for demanding fluid and gas piping systems. Plumbers, pipefitters, and mechanical contractors install this gasket between mating flanges to create a leak-tight seal at pipe joints in industrial and commercial installations.

This flange gasket is used in flanged pipe assemblies where a reliable, compression-style seal is required. The aramid fiber fiberglass construction handles elevated temperatures and pressures found in steam, hot water, chemical, and process piping systems. It is sold individually and fits standard 3-inch nominal pipe flanges, making it a straightforward drop-in component during new construction or maintenance shutdowns.

Compatibility

Designed as an OEM-style replacement or new-installation gasket for standard 3-inch nominal pipe flange assemblies in plumbing, process piping, and mechanical systems.

Installation Notes

Flange gasket installation is typically performed by licensed plumbers or pipefitters in accordance with applicable IPC and ASME B16 piping codes. Isolate and depressurize the line and verify zero pressure before breaking the flange joint. Inspect flange faces for scoring or corrosion before seating the new gasket. Tighten flange bolts in a cross pattern to achieve uniform compression without over-stressing the gasket material.
