Ndi tepi yosindikizira ya PTFE iyi, palibe chifukwa chogwiritsa ntchito chitoliro chomata, chosokonekera mukakonza.Tepi ya PTFE ndiyabwino kupanga zosindikizira zachangu, zaukhondo, zosagwirizana ndi mpweya.Ndi oyenera madzi, mpweya kapena mpweya mizere ndi ntchito pa ulusi zitsulo kapena PVC pipe.Quick, woyera, mpweya zosindikizira; Ntchito pa ulusi zitsulo kapena PVC chitoliro; Abwino madzi, mpweya kapena mpweya mizere.
Tepi yosindikizira ulusi (yomwe imadziwikanso kuti PTFE tepi kapena plumber's tepi) ndi filimu ya polytetrafluoroethylene (PTFE) yogwiritsidwa ntchito posindikiza ulusi wa mapaipi.Tepiyo imagulitsidwa yodulidwa kuti ikhale m'lifupi mwake ndikumangirira pa spool, zomwe zimapangitsa kuti zikhale zosavuta kupota ulusi wa chitoliro.Amadziwikanso ndi tepi ya polima yopangidwa ndi genericized;pomwe ma polima ali ofanana ndi PTFE, Chemours (omwe ali ndi zizindikiro) amawona kuti kugwiritsa ntchito uku ndikolakwika, makamaka popeza sapanganso polima ngati tepi.Ma tepi osindikizira a Thread seal amalola kuti ulusiwo ukhale wozama kwambiri, ndipo umathandizira kuti ulusiwo usagwire akamamasulidwa.Tepiyo imagwiranso ntchito ngati chodzaza chopunduka ndi mafuta opangira ulusi, kuthandiza kusindikiza mgwirizano popanda kuumitsa kapena kupangitsa kuti zikhale zovuta kumangirira, ndipo m'malo mwake zimapangitsa kuti zikhale zosavuta kumangirira.
Mitundu
Tepi yosindikizira ya Thread yomwe imagwiritsidwa ntchito popanga mapaipi nthawi zambiri imakhala yoyera, koma imapezekanso mumitundu yosiyanasiyana.Nthawi zambiri amagwiritsidwa ntchito kuti agwirizane ndi mapaipi amitundu (US, Canada, Australia ndi New Zealand: chikasu ngati mpweya wachilengedwe, wobiriwira ngati mpweya, ndi zina zotero). Ku UK, tepi imagwiritsidwa ntchito kuchokera ku ma reel achikuda, mwachitsanzo, ma reel achikasu a gasi, wobiriwira kwa madzi akumwa.
* Yoyera - yogwiritsidwa ntchito pa ulusi wa NPT mpaka 3/8 inch * Yellow - yogwiritsidwa ntchito pa ulusi wa NPT 1/2 inchi mpaka 2 inchi, nthawi zambiri imatchedwa "tepi ya gasi" * Pinki - yogwiritsidwa ntchito pa ulusi wa NPT 1/2 inchi mpaka 2 inchi, otetezeka a propane ndi mafuta ena a hydrocarbon* Wobiriwira - wopanda mafuta PTFE wogwiritsidwa ntchito pa mizere ya okosijeni ndi mpweya wina wamankhwala* Wotuwa - uli ndi faifi tambala, anti-seizing, anti-galling and anti-corrosion, umagwiritsidwa ntchito popanga mapaipi osapanga dzimbiri* Copper - ili ndi tinthu ta mkuwa ndipo imatsimikiziridwa ngati mafuta opangira ulusi koma osati osindikizira
