PPR yeeb fittings chaw tsim tshuaj paus hais tias PPR yeeb nkab phom sij yuav tsum tau kuaj rau hydraulic siab tom qab kev txhim kho. Yog tias nws yog ib qho yeeb nkab uas tsaus nti, nws yuav tsum tau zais cov yeeb nkab tom qab ntsuas dej.
Cov kauj ruam ntawm cov yeeb hydraulic hydraulic kuaj yog kom nres qhov kawg ntawm lub siab ntsuas tube, maj mam sau cov dej, thiab cov pa tawm hauv cov yeeb nkab tib lub sijhawm.
