Mugihe cyo gufunga gasketi ya fibre synthique fibre izunguruka, hari amahitamo make ashobora gutekerezwa bitewe nibisabwa byihariye bya porogaramu.Hano haribintu bike bishoboka: Gasketi ya Fibre-Yongerewe ingufu Gas Gasketi ya PTFE ; Rubber cyangwa Elastomer Gaskets gas Igipapuro cyuma, nka gaze ya aluminiyumu, gasi ya koperative, icyuma kitagira umwanda, icyuma cya fibre.
Mugihe uhitamo icyuma gifunga fibre ikomatanya, ni ngombwa gusuzuma ibintu nkibikorwa (ubushyuhe, umuvuduko, hamwe n’imiti ikoreshwa), igishushanyo mbonera cy’ibikoresho, hamwe no guhuza fibre yihariye ikorwa.
Byaba byiza kugisha inama na Futai, ushobora gutanga ubuyobozi bwinzobere kandi akanasaba amahitamo meza kubyo usaba.
