2 in tee insulation for 1-1/2 in pipe

Nomaco Kflex 801-T-100200 is a closed-cell Buna-N rubber/PVC tee fitting insulation designed for 2 in outside-diameter tube and 1-1/2 in pipe size. The unslit form slides over the joint and stays flexible from -297 °F to 220 °F while delivering an R value of 6.7. Plenum rating and UL 94 compliance suit commercial mechanical systems.

Verify pipe size and clearance

Confirm the run pipe measures 1-1/2 in nominal and the branch matches the 2 in inside diameter before ordering. The unslit sleeve requires enough room to slide over the assembled tee, so check surrounding obstructions and support spacing. Antimicrobial, flame-retardant foam meets a flame spread index of 25 for plenum installations.

Replaces wrap or tape on tee joints

This pre-formed tee eliminates cutting and taping flat insulation around three-way connections, saving labour on chilled-water, refrigerant or hot-water lines. The jump is worth it when consistent thickness, vapour-barrier integrity and code-compliant plenum rating are required on 1 in wall-thickness specifications.

Questions about this item

What comes with the Nomaco Kflex 801-T-100200 tee fitting insulation, and do I need to buy adhesive or tape separately?

The package contains the pre-formed elastomeric tee fitting insulation made from Buna-N rubber/PVC blend. Adhesive, tape, or other installation accessories are not included and must be purchased separately.

The supplier title shows 2 in x 59/64 in with a 1 in wall — which measurement matches my 1 1/2 in pipe size?

The product is designed for a 1 1/2 in pipe size, which corresponds to a 2 in tube outside diameter. The 1 in wall thickness provides the listed R-value of 6.7 for that pipe size.

With a flame spread index of 25 and UL 94 rating, what does that mean for a plenum installation?

A flame spread index of 25 and UL 94 compliance indicate the material meets low-flame-spread requirements. Combined with the plenum rating, this tee fitting insulation is approved for use in air-handling plenums.
