Product Description
Lap Joint Stub End is a type of stub end that is customarily used with lap joint flanges, the stub end forming the face of the flange. Applications where constant disconnection and dismantling of pipes is needed are benefitted through these fittings as they give a quick disassembly, allowing inspection adn cleaning of pipelines.
