Type 1 EZ Seal Clamp

TorcTite™ - the “Seal of Strength”

Product Feature

TorcTite’s exclusive, pliable aluminum reaction block conforms tightly to exhaust components providing a superior seal.

undefined
Benefit to You!

During installation, the block conforms to the I.D.-O.D. step between pipes, creating a unique seal. The block actually digs into flex hose spirals. Other clamps leave leaky gaps between the clamp band ends and pipes; TorcTite’s patented reaction block, specially-formed band and fasteners all work together to seal these leaks. And it seals without loose gaskets or sealant additives.

Product Feature

TorcTite’s reaction block will not pinch flex hose and pipes, which means TorcTite will not cause leak paths or damage expensive exhaust components.

undefined
Benefit to You!

Other inferior clamps pinch exhaust pipes and flex hose during installation, creating exhaust leak paths. TorcTite’s reaction block completes a full 360 degree compressive seal without damage – eliminating pinching, distortion and damage to pipes. Expensive flex hose, pipes and muffler inlets remain unharmed.

Product Feature

TorcTites’s exclusive reaction block and independent force bars prevent bolt bending and clamp binding which makes installation time fast and easy.

undefined
Benefit to You!

A balanced transfer of forces among TorcTite’s specially formed band, reaction block and independent force bars eliminates bending forces on bolts, which keeps installation torque very low. Clamp binding is eliminated, too. The unique balanced design results in a strong, tightly-sealed exhaust joint that assembles quickly and reliably.

Product Feature

TorcTite is the only clamp with fastener hardware pre-attached to a bright-finish band.

undefined
Benefit to You!

Installation is fast, easy and accurate. Simply wrap the clamp band with its pre-attached hardware around pipes; insert the extra-long bolts through opposite clamp end, force bars and nuts; and torque. No dropping or fumbling with loose or excessive parts. The pre-formed band makes an accurate I.D.-O.D. installation even easier, and causes no damaging distortion to pipe or flex hose. The high-tensile steel with TorcTite’s exclusive reaction block has greater stretching capability than other band clamps.
