Value Collection 3194786 Flange Gasket 4 in Pipe

Product Description

The VALUE COLLECTION 3194786 is a flange gasket designed for use on 4-inch nominal pipe size connections. It features a 5-inch inside diameter and a 7-1/8-inch outside diameter, providing a reliable sealing surface between mating flanges. Constructed from carbon steel and stainless steel, this gasket is rated for a temperature range of -440 degrees F to 850 degrees F, making it suitable for demanding industrial and commercial piping applications. Plumbers, pipefitters, and mechanical contractors typically install this type of gasket during flange assembly or replacement service on process piping, HVAC hydronic systems, and similar installations.

This gasket is suited for 4-inch nominal pipe flange connections where a metal gasket is required to handle elevated temperatures or corrosive service conditions. It is appropriate for use in both commercial and industrial settings, including steam lines, hot water systems, and process piping where standard elastomeric gaskets are not rated for the operating conditions. The dual-material construction — carbon steel and stainless steel — supports a broad range of fluid and gas service environments.

Compatibility

Designed as a replacement or new-installation flange gasket for 4-inch nominal pipe size flanged connections requiring a metal gasket with a 5-inch ID and 7-1/8-inch OD.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable piping codes such as ASME B16.21 and ASME B31. Depressurize and isolate the piping system completely before removing old gaskets or breaking any flange connection. Inspect flange faces for corrosion or damage prior to seating the new gasket. Follow the flange bolt torque sequence recommended by the applicable piping standard to ensure even gasket compression and a leak-free seal.
