All service jacketing tape (3" or 4"). Insulators use ASJ tape for taping linear pieces of fiberglass insulation together, installing pvc fittings, or fabricating anything with ASJ jacketing. At Buy Insulation Products.com, we recommend buying atleast 1 roll of ASJ tape for fiberglass pipe insulation orders over 100 linear feet to help seal up exposed fiberglass from cuts made to the pipe insulation from the fabrication of tees, 90s, 45's, etc.
Roll Length: 50 yards

The ASJ tape has a brown wax paper that you must peel off which is hard to do without longer fingernails. The ASJ strip that come with the fiberglass pipe insulation has a corner that allows easy separation. Overall the tape sticks fine and the roll is very long so make sure not to over order.
All prices are in USD.
