The Allpoints 321775 Narrow Gasket provides a reliable seal to help prevent leaks in commercial plumbing and foodservice equipment connections. Designed as a BJ narrow flange gasket and supplied in a 12-pack, it is compatible with both narrow and wide flange nipples for flexible installation. It works by compressing between mating surfaces when tightened, creating a tight barrier that stops the escape of liquids or gases under pressure. This simple sealing function helps maintain system integrity and stable operation. Its durable, chemical-resistant construction supports long service life, reduces maintenance needs, and contributes to efficient, leak-free performance in demanding kitchen and facility environments.
