The Armor Seal™ is not designed to withstand

the weight or the axial forces of the pipe. Conrm

that the product label matches your application.

Armor Seal™ is compatible with steel, CI, DI, A/C, Concrete,
PVC and HDPE pipe.

Pipe stiffeners are required when coupling HDPE pipe.

Step 1 • Thoroughly clean pipe surface that will be

covered by the clamp. Remove any irregularities on the dam­aged area or the pipe ends. To help position the clamp, place
reference marks on the pipe slightly wider than the clamp.

Step 3 • Place the gasket around the pipe using the

reference marks made in Step 1. Make sure the gasket slides
between the tab and the shell.

NOTE: Do not cut the gasket.

Close the clamp and start the bolts.

If necessary, because of owing water, Step 3 can be per­formed beside the crack or hole. Slide the clamp over the dam­age and begin the bolt tightening.

Step 4 • Do not rotate the coupling or the pipe

during tightening.

NOTE: Do not exceed the torque requirements
indicated on the product label.

On clamps with three bolts, start at the center bolt, and begin
tightening all bolts evenly. Keeping the torque as even as pos­sible between bolts, apply the required torque.

Step 2 • Loosen the bolts with the o-rings until the

clamp can be opened.
