Plasson Long Spigot Stub Flange
Engineered for demanding pipeline applications, the Plasson Long Spigot Stub Flange delivers a secure, reliable connection where performance truly matters. Its flat flanged end mates seamlessly with metallic or plastic backing rings, locking into another flange via a bolt circle for a dependable, leak free joint. The long spigot end is built for electrofusion welding or butt fusion, making it the go to choice for high pressure water, gas, and industrial systems. With an SDR11 rating a precise wall thickness to outer diameter ratio,-it stands up to serious pressure, handling up to 16 bar for water and PN10 for gas pipelines. Best of all, that generous spigot length gives installers room to work, allowing electrofusion couplers to be fitted with ease while protecting the flange seal area from heat related warping or damage during welding. 

Summary: 

• Flat flanged end is designed to be mated with metallic or plastic backing rings
