ArmaFlex pipe insulation 1/2 inch is elastomeric foam tube for 1/2 inch pipe in HVAC, refrigeration and plumbing work.
It keeps cold lines dry and reduces energy loss. Order it with the matching copper pipe size.
What is an armaflex pipe insulation 1/2 inch?
Armaflex tubes are flexible, closed-cell elastomeric foam insulation made to slide over pipes. The closed cells resist water vapour, so the insulation stops condensation forming on cold pipes as well as cutting heat gain.
Tubes are named by the outside diameter of the pipe they fit. Therefore, a 1/2 inch tube fits 1/2 inch copper pipe. Wall thickness is chosen by how cold the pipe runs and how humid the space is.
