Armaflex EVO Insulation Coil
Armacell AF/Armaflex EVO closed-cell elastomeric foam insulation coil in 9mm and 13mm wall thickness — the benchmark product for refrigerant pipework insulation on air conditioning and refrigeration systems. 15m coil format for bulk installs and long pipe runs. Class O fire-rated, vapour-tight, and resistant to UV degradation. Compatible with K-420 adhesive and standard insulation tape for joint sealing.
Armaflex EVO Tuffcoat Underground Insulation
Tuffcoat is Armacell's specialist external and underground pipe insulation — UV-resistant, waterproof, and designed for exposed outdoor pipework and buried applications where standard nitrile rubber insulation will degrade. 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.
