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.
