Push-in fittings - Import export

Metzner has developed the mandrel cutting machines of the SR series for cutting off sealing rings from injection-moulded or extruded tubes with different diameters. These machines are characterised by their unique processing method and high cutting quality. First, pre-extended "rubber tubes" are clamped onto mandrels. Due to the special design of the mandrels, the mandrel can be set up and removed quickly and without special previous knowledge. The mandrels are then automatically clamped in the machine between rotating spindles and production is started. A knife carriage travels along the tubes and cuts the flat sealing rings to the desired length with either push-fit or circular knives, depending on the requirements. This cutting method is particularly impressive with its high cutting quality in combination with a high output.

Our fittings has been designed by our own European Engineers team. We designed an innovative a profile which avoids the risk of damaging the O-rings when the pipe is pushed on to the fitting. Our fittings high quality is based on: – Patented design brass fitting, with three EPDM O-rings and inox sleeves. – Triple safety with three O-rings in the designed fitting. – Manufactured under the technical standards DIN 50930-6 and UNE EN ISO 21003-3. – Compatible with multilayer pipes. – Compatible with several jaw profiles U, H, TH, RFz – Lead free brass available on request.
