Clamp (los yog Cinch) Fittings:
Clamp fittings, tseem hu ua cinch fittings, siv stainless hlau rings thiab ib tug clamp cuab tam kom ruaj lub tubing rau lub haum. Lawv muab txoj hauv kev yooj yim thiab yooj yim installation yam tsis tas yuav muaj cov cuab yeej tshwj xeeb. Clamp fittings yog tsim rau DIY tej yaam num thiab feem ntau siv nyob rau hauv nruj qhov chaw uas crimping cov cuab yeej yuav nyuaj rau maneuver.
Push-to-Connect Fittings:
Push-to-connect fittings muab txoj hauv kev yooj yim thiab tsis muaj kev teeb tsa rau kev txuas PEX tubing. Cov fittings no muaj lub collet thiab O-ring tsim uas tso cai rau cov raj xa mus rau hauv qhov haum rau kev sib txuas ruaj ntseg. Push-to-connect fittings yog qhov zoo tagnrho rau DIYers thiab cov ntawv thov uas ceev thiab yooj yim yog qhov tseem ceeb.
Xovxwm Fittings:
Xovxwm fittings siv lub cuab yeej xovxwm los txhawm rau lub tes tsho hlau ncig PEX tubing, tsim kom muaj kev ruaj ntseg thiab tsis muaj dej. Lawv muab kev ua tau zoo txhim khu kev qha thiab feem ntau yog siv hauv kev tsim cov kav dej. Xovxwm fittings muab cov kev daws teeb meem ruaj khov thiab tsis muaj paug rau ob qho tib si hauv tsev thiab kev lag luam.
Kev siv PEX Fittings:
PEX fittings yog siv nyob rau hauv ntau yam kev siv cov kav dej, suav nrog cov dej kub thiab dej txias, cov cua kub hauv pem teb, cov cua sov hydronic, thiab cov tshuab daus yaj. Lawv tau sib xws nrog PEX tubing ntawm ntau qhov sib txawv thiab ntau hom, ua rau lawv haum rau ntau yam haujlwm.
Txheej txheem installation:
Txhim kho PEX fittings yog cov txheej txheem ncaj qha uas yuav tsum muaj ob peb yam cuab yeej thiab cov tswv yim. Pib los ntawm kev txiav PEX tubing mus rau qhov xav tau ntev siv PEX tubing cutter. Xyuas kom tseeb tias qhov kev txiav yog ncaj thiab huv si kom ua tiav lub foob kom raug. Tom ntej no, ntxig lub raj rau hauv qhov haum kom txog thaum nws mus txog qhov haum lub xub pwg. Rau crimp thiab clamp fittings, siv cov cuab yeej tsim nyog los tiv thaiv kev sib txuas. Rau kev thawb-rau-txuas thiab nias fittings, ua raws li cov chaw tsim khoom cov lus qhia rau kev teeb tsa.
Hauv kev xaus, PEX fittings muab ntau yam kev daws teeb meem thiab txhim khu kev qha rau cov kav dej hauv cov tsev nyob thiab cov tsev lag luam. Txawm hais tias koj tab tom txuas PEX tubing rau kev faib dej kub thiab dej txias lossis txhim kho cov cua sov hauv pem teb, muaj PEX haum haum rau koj cov kev xav tau. Los ntawm kev nkag siab txog ntau hom PEX fittings, lawv siv, thiab ua raws li cov txheej txheem kev teeb tsa kom raug, cov tswv tsev thiab cov kws tshaj lij tuaj yeem ua tiav cov kav dej ruaj khov thiab tsis muaj paug rau xyoo tom ntej.
