Armaflex Flexifast
Secure flexibility that saves time
Armaflex Flexifast is a reliable pre-insulated system solution to connect indoor and outdoor units of split- and multi-split air conditioning systems. The flexible rubber hose is assembled with straight end fittings pre-applied to each end and the complete system comes pre-insulated with closed cell Armaflex AC insulation.

The system is easy to install, reduces both cost and time of assembly, avoids condensation and is suitable for use with the new refrigeration gases R134, R404, R407 & R410.
