Ukufakwa kwepayipi elihlangene eliphelele le-seal seal kwenziwa ngensimbi epuletiwe futhi ixhuma umoya wokucindezela okuphezulu nepayipi lesitimu kuxhumano lwentambo ye-NPT yesilisa. Inomkhawulo ohlabayo ukuze udale isivalo esiqinile epayipini uma isetshenziswa nge-hose clamp noma umkhono wecrimp noma i-ferrule (ayifakiwe) kanye nemicu yesifazane ye-National Pipe Taper (NPT) ngakolunye ukuze ixhume ekuxhumekeni kwentambo ye-NPT yabesilisa. Lokhu kuhlanganisa kwenziwa ngensimbi ecwebezelayo ukuze ibe namandla, ithambile, idubule, futhi imelane nokugqwala, futhi inesihlalo se-polymer sokumelana namakhemikhali. Lokhu kufakwa kwepayipi eliphelele le-Boss elihlanganisiwe kunconywa ukuze kusetshenziswe isitimu esifinyelela ku-450 degrees F.
