Essential for any external pipe run on split system or VRF installations. Available in 1m lengths for precise cutting to requirement.
Armacell Tubolit DuoSplit Pre-Insulated Twin Copper Pipe
Tubolit DuoSplit is pre-insulated twin copper pipe for air conditioning refrigerant circuits — liquid and suction lines factory-insulated and paired in a single product for fast, clean installation. Available in three size combinations: 1/4" & 3/8", 1/4" & 1/2", and 3/8" & 5/8" — covering all standard residential and light commercial split system pipe sizes. 25m coil. Significantly reduces installation time versus separate pipe and insulation.
Completing an Armacell Installation
All Armaflex joints, cut ends, and seams require sealing with K-420 contact adhesive and insulation tape to maintain the vapour barrier. Incomplete sealing is the primary cause of condensation failure on insulated pipework. Both are stocked under Pipe Insulation Accessories.
