About the Design

The Flexible Rigidity™ of HI-TORQ couplings allows them to hold the pipes rigidly in place, but to flex when necessary to compensate for the normal movement of the pipe. There's never a failure and that's guaranteed.

Flexible

The patented slotted edge coupling shields of the Clamp-All HI-TORQ 80 & 125 are designed to allow a far greater tolerance in pipe-to-fitting diameters or in irregularities of shape. Hydrostatic seal can be maintained at our rated working pressure of 15 PSI even with up to 1/4 inch of variation.

The gasket has two sets of sealing beads on each side of the center stop for a secure seal on irregular pipe or fitting surfaces. The raised outer band fits into the raised portion of the shield and aids in alignment during installation. There's no guess, no slips, or eyeball adjustments that waste time or weaken the seal.

Rigiditity

The wide body design of Clamp-All HI-TORQ 80 and 125 couplings provides maximum strength and support for piping systems above and below ground. Testing and approval to Factory Mutual Research Standard FM 1680 Class l proves the ability of Clamp-All HI-TORQ 80 &125 couplings to withstand extreme shear, high deflection, and severe vibration without a leak.

About Specifications

Clamp-All HI-TORQ 80 & HI-TORQ 125 couplings are designed and suitable for use with hubless cast iron pipe and fittings conforming to CISPI 301-85 for all storm and sanitary DWV piping systems above and below grade.

Clamp-All couplings when used with Snap-All® transition bushings are suitable for use with PVC , steel, and copper pipe in all storm and sanitary DWV piping applications for joining dissimilar materials and or sizes.

About Performance

Clamp-All relies on thorough third party testing from independent and industry respected laboratories to demonstrate the performance of Clamp-All couplings far beyond routine service conditions.

Factory Mutual Research
World renowned in loss prevention, this insurance underwriting organization tests, evaluates and approves materials as a way of reducing loss in buildings insured by their carriers. Clamp-All HI-Torq 80 &125 coupling are each approved to FM’s Standard 1680, Class 1, at 15 PSI rated working pressure and each coupling is clearly and proudly marked with the FM logo and 15 PSI pressure rating.

Through such independent third party tests, Clamp-All couplings demonstrate their superior performance, allowing each coupling to be used with confidence in high risk jobs – schools, hospitals, jails, museums, sports facilities, commercial and industrial projects
. . . without a failure . . . ever!
