6-5 JOINTS

Joints serve several purposes in a drainage system. Their primary purpose is to preserve the structural integrity by keeping the embedment material out of the system. Well-designed joints also preserve the hydraulic properties of the pipe by maintaining alignment between pipe ends. Joints can keep effluent inside the pipe, which is necessary when environmental issues are a concern.  Site-specific requirements or local regulations will usually dictate the quality of joint required.

Two Sure-Lok joint designs are available to meet the increasing demands on joint performance. The Hancor Sure-Lok F477 joining system provides a non-rated watertight joint. Hancor Sure-Lok WT is a rated watertight joining system.
