Ikinyugunyugu cya PTFE gitondekanya isahani yikinyugunyugu ya PTFE ifite ubuso bwa kashe.Umuyoboro uroroshye gukora, ufite imikorere ifunze neza, nubuzima burebure;irashobora gukoreshwa mugukata vuba cyangwa guhinduka.Bikwiranye nibihe bisaba kashe yizewe hamwe nibiranga ihinduka.Umubiri wa valve ufata ubwoko bwacitsemo ibice, kandi gufunga kumpande zombi zomugozi wa valve bigenzurwa nuburinganire bwibanze hagati yisahani yikinyugunyugu nintebe ya valve wongeyeho reberi ya fluor;kugirango umenye neza ko shitingi ya valve idahuza n'amazi yo mu cyumba.Birakoreshwa cyane mu gutwara amazi na gaze (harimo na parike) muburyo butandukanye bwimiyoboro yinganda, no gukoresha itangazamakuru ryangirika cyane, nka: aside sulfurike, aside hydrofluoric, aside fosifori, chlorine, alkali ikomeye nibindi bitangazamakuru byangirika cyane.
