FRIAFIT couplers provide a lasting connection for pipe systems made from HD-PE which is tight and longitudinally strong. Due to the superior electrofusion technology pipe and coupler become an inseparable unit giving in-growing roots no chance at all.
designed as slide-over coupler without centre stop for equally bottom levelled pipe connections without coupler gap
external reinforcement on large couplers for stability and optimum molten pressure during fusion
low weight even with larger dimensions
