PUHUI PP compression fittings are suitable for irrigation networks and industrial applications.Used with all types of PE pipes produced in accordance with International Standards.Available in a wide range of products : male connections, quick couplings, elbows, tees, terminals etc.Sizes from 20mm up to 110mm, threaded from ½" up to 4" BSP.
All PP fittings produced by Palaplast are designed and manufactured according to International Standards for compression fittings.Material used for the manufacture of fittings is PP based on polypropylene with additional specialized substances of high standards.O-rings used in the fittings are made of NBR.
PP compression fittings:
The PP compression fitting is a pipe fitting that is mechanically attached. To ensure a perfect hydraulic seal in a pressurized dispensing structure, PP compression fittings require physical forces to form a seal or create alignment. Unlike traditional hot melt for HDPE pipes, PP compression accessories offer a quick, simple and simple new installation method.
PP compression fittings are widely used for water supply and irrigation. PUHUI PP compression joints are manufactured in accordance with EN 712/713/715/911; ISO 3501/3503/3458/3459. The fittings can be mounted on HDPE pipes in accordance with ISO 11922; DIN 8072/8074; UNE 53131. Threaded versions are manufactured in accordance with ISO 7 and DIN 2999.
