Central Plastics

Due to the unique material characteristics of polyethylene, heat fusion allows successful joining of pipe and fittings into a single leak-free system with no connections to corrode or loosen.

"The basic principle of heat fusion (in this case butt, saddle or socket fusion) is to heat and melt the joint surfaces and force the melted surfaces together, which causes the materials to mix and fuse into a monolithic joint." AWWA PE Pipe - Design and Installation, Manual of Water Supply Practices M55.
