Installation Tools 

There’s no soldering, gluing or threading of pipe; a simple pipe cutter and de-burring tool are the only tools required.

A roll grooving tool will no longer be needed with the larger fittings 80mm-168mm making for a quicker installation. 




Unless otherwise specified by the product seller in a separate written product warranty accompanying the product or specified in the seller's product catalogue, AIGNEP USA warrants to the End User that its INFINITY Fittings and Aluminum Tubes shall be free from substantial defects in materials and workmanship for a period of twenty years from the Installation Date.
