I-PEX copper fittings iyizixhumi zensimbi ezisetshenziselwa ukuhlanganisa ama-PEX pipes (ama-pipes e-cross-linked polyethylene). Ngokuvamile zifaka ama-elbows, ama-tees, kanye nezixhumi, zifeza ukuhlanganiswa okuvalekile phakathi kwe-PEX pipe kanye ne-copper fitting ngezindlela ezifana nokucindezela, ukwandisa, noma ukuhlanganiswa okunezintambo. Zisetshenziswa kakhulu ekwakheni ukuhlinzekwa kwamanzi, ezinhlelweni zokushisa, nasezinhlelweni zokushisa phansi.

Isici esiyinhloko se-PEX copper fittings sitholakala ekuhlanganiseni izinzuzo ze-PEX pipes kanye ne-copper fittings: I-PEX pipes inikeza ukumelana nokugqwala, ukumelana nokudlidliza, nokuphila isikhathi eside (ngaphezu kweminyaka engu-50), kanti i-copper fittings inikeza amandla aphezulu emishini, ukumelana nezinga lokushisa eliphezulu (ububanzi bezinga lokushisa obuvamile obusebenza -70℃ kuya ku-110℃), kanye nokumelana nokukhathala okuhle, kuqinisekisa ukuxhumana okuthembekile. Le nhlanganisela ikakhulukazi ifanelekile kuzinhlelo ezidinga ukuphepha okuphezulu nokuhlala isikhathi eside, njengeziteshi zamanzi ashisayo nezibandayo ezindlini kanye nokushisa ngaphansi komhlaba. Ngokuqondene nokuhlukaniswa nezindinganiso, i-PEX copper pipe fittings kumele ihambisane nohlobo lwe-PEX pipe (isb. PEX-a, PEX-b, noma PEX-c). Izindlela ezihlukene zokuxhumanisa zithinta ukumelana nokushisa kanye nokumelana nokuphuka kwezinto zeph pipe; ngakho-ke, kubalulekile ukuqinisekisa ukuthi i-pipe fittings kanye ne-PEX pipes zifana ngegade kanye nezinto lapho kukhethwa khona amafitting. Imikhiqizo kumele ihambisane nezindinganiso ezifanele, njenge-GB/T 18992 mayelana nezilinganiso zengcindezi kanye nez tolerance zedimensions, kanye ne-CJ/T205-2000 ne-CJJ/T98-2003 mayelana nokumelana nezinga lokushisa, izinga lokuxhumanisa (ngokuvamile 70%-89%), kanye nokumelana nokudlidliza. Amafitting ngokwawo kumele adlule ku-95℃/1.5MPa hydrostatic test futhi ahlangabezane nezidingo zamandla okudonsa.
