I-PEX pipe fittings yizixhumi zamapayipi nezinto zokwabiwa ezenziwe nge-polyethylene exhunywe (PEX) njengempahla eyinhloko, ezivame ukusetshenziswa ezinhlelweni zokuhlinzeka ngamanzi nezokushisa ezakhiweni.

Izinto zokwakha nezinqubo zokukhiqiza: Impahla eyinhloko ye-PEX pipe fittings iyiphayiphi ye-polyethylene enedensity ephezulu (HDPE). Ngendlela yokuxhumanisa, isakhiwo se-molecular esihlinzekiwe sishintshwa sibe isakhiwo se-network esithathu, ngaleyo ndlela kuthuthukiswe ukumelana nokushisa, ukumelana nokukhululeka, kanye nokuzinza kwemichiza.
