The MIDLAND INDUSTRIES 988406 is a full face gasket designed to seal flanged pipe connections in plumbing, industrial piping, and valve assemblies. Constructed from red rubber, this gasket compresses evenly across the full face of a flange to prevent leaks at bolted joints. With an 8 inch inside diameter, it fits standard 8 inch pipe flanges and is commonly installed by licensed plumbers and pipefitters in both commercial and industrial piping systems. Red rubber material provides reliable sealing performance across a range of water and fluid service applications.
This gasket is suited for use in flanged valve assemblies, pipe connections, and fluid handling systems where a full face seal is required. Full face gaskets are typically specified when working with flat-face flanges, such as cast iron or ductite flanges, where the gasket must span the entire flange face to distribute bolt load evenly and prevent flange damage. This makes the 988406 a practical choice for waterworks, mechanical rooms, and industrial piping installations requiring reliable static sealing.
Designed as an OEM-style replacement full face gasket for standard 8 inch pipe flange connections in flanged valve and piping assemblies.
Installation is performed by licensed plumbers or pipefitters. Depressurize and drain the pipeline completely before disassembling flanged joints. Clean both flange faces of old gasket material and debris before seating the new gasket. Tighten flange bolts in a cross pattern to the torque specifications outlined in applicable piping codes such as ASME B16.21 or the valve or flange manufacturer guidance.
