    • Pro Installation

This 2" diameter (I.D.) supply tubing is made of 3-ply aluminum, making it flexible yet strong. This supply tubing comes with vapor barrier and R-8 insulation to meet new codes where R-8 is required in uninsulated or unconditioned space. R-8 insulated supply tubing comes in 75 foot lengths to reduce the number of joints between your plenum and outlets. Supply tubing snaps together easily with the use of Kwik Connects.

Supply tubing connects to the plenum with SpacePak Plenum Take-offs, and must be matched with an Installation Common Parts Kit to complete the supply outlet. Depending on how many supply runs you need to make, SpacePak Plenum Take-offs and Installation Common Parts Kits are sold separately in packs of (2) and (5). Please click on the Accessories tab above to choose a kit that works best for your number of intended outlets.
