Hydraulic coupler

for pipesHDPE

For the subsequent incorporation of a PE-HD pipeline into a cast-iron piping system, you will find the appropriate solution at Reinert-Ritz. With the combination of the REINOGRIP patented push-fit system and the Düker SPEZIAL thrust-resisting joint, you can create longitudinally force-locked transitions between the two pipe materials. Secure sealing is ensured on the PE side by means of an EPDM lip seal and via an EPDM-Tyton® seal on the cast iron side. The fittings to be offered must be manufactured from material in compliance with the PE100+ Association and according to DIN EN 12201 with respect to dimensions, tolerances and quality requirements. Proof must be provided that they were manufactured on the basis of a quality assurance system in accordance with DIN EN ISO 9001. For all fittings a certificate in accordance with DIN EN 10204 must be submitted by the manufacturer. The body of the fitting must be manufactured in the injection moulding process or alternatively, in the case of more complex structures, from a piece of homogeneous semi-finished material so as to ensure the required reinforcement and therefore high stability of the fitting. Semi-finished materials manufactured from wound rods or the subsequent application of other forms of reinforcing are not permitted. The pull-resistant push-fit couplers must have grip elements with at least 5 grip teeth respectively made of high-strength plastic and that are arranged on spring-loaded supports. The self-activation of the grip must be ensured by an elastomer ring. At the push-fit coupler inlet an elastomer profile ring must be arranged as a wiper that prevents the penetration of dirt.
