...Cost Effective for all DWV Systems

The HI-TORQ 80 coupling from Clamp-All is engineered to be the most cost effective way to join any hubless DWV system in high risk environments....and be assured of an easy installation and a trouble-free job.

• HI-TORQ 80 couplings are cost effective for joining all high risk DWV storm and sanitary piping systems, above or below grade.  Installation is quick, secure and trouble free.

• HI-TORQ 80's unique flexible rigidity provides the strength required to maintain hydrostatic integrity even under severe stress.

• HI-TORQ 80's slotted shield design compensates for mismatched pipe/fitting diameter and maintains alignment.

• HI-TORQ 80 couplings have just two clamps for sizes through 4" (100 mm) and only four clamps on sizes 5" (125 mm) to 10" (250 mm).  That means quicker installation.
