Gasket 1/4"Buna For 4" Dust

Gasket 1/4"Buna For 4" Dust

This is a replacement 1/4" thick Buna-N gasket for 4-inch dust collection system components. It is most commonly used as a seal for 4-inch butterfly valves that control the flow of captured cement dust, or as a flange gasket for connecting 4-inch dust pipes and ductwork. Made from durable Buna-N rubber, it provides excellent resistance to abrasion and petroleum-based oils. This gasket is a critical maintenance part for ensuring a dust-tight seal, preventing leaks, and maintaining the efficiency of dust control systems from manufacturers like Con-E-Co, Vince Hagan, and WAM.
