Hela couplings

HELA couplings for pre-insulated pipes are manufactured in accordance with the ISO 15875-5 standard. They are made from dezincification-resistant brass, allowing safe use for drinking water transmission and approved by hygienic certification (NIZP-PZH).

Our screw-compression couplings are clearly marked with the nominal diameter, carrier pipe wall thickness and pressure class (PN6 or PN10).

The compact design of the couplings minimises storage space requirements, while the innovative construction enables quick and simple installation without the need for specialised hydraulic tools. The couplings are fitted as standard with taper threads in compliance with ISO 7.
