The range of NIRON electrofusion couplers is available today from Ø1/2" to Ø12" SDR 7.3 to meet all installation needs thanks to the continuous investments in Research & Development. NIRON is a system produced using a new generation material and a new formulation process that allow the pipes produced with this material to withstand higher pressure levels and ensures high mechanical resistance and duration, even at high temperatures and pressures.
