JCM 412 Fabricated Tapping Sleeve The JCM 412 Fabricated Tapping Sleeve is a safe, economical solution to tapping today’s pipelines. Custom engineering service assures proper fit and conformation to the pipe diameter increasing safety factor and installation efficiency. By directly reinforcing the pipe, the sleeve eliminates flexing or deflection of the pipe opposite of the tap. The large cross section gasket provides a positive initial seal which increases with increases in line pressure. The JCM 412 Tapping Sleeve is available in various option styles and materials.
