Rabala yachilengedweNdi yoyenera madzi, madzi a m'nyanja, mpweya, mpweya wopanda madzi, alkali, madzi amchere ndi zinthu zina, koma si yolimbana ndi mafuta amchere ndi zosungunulira zopanda polar, kutentha kwa nthawi yayitali sikupitirira 90℃, kutentha kochepa ndikwabwino kwambiri, kungagwiritsidwe ntchito pamwamba pa -60℃.

  Rabala ya nitrileNdi yoyenera zinthu zamafuta monga mafuta, mafuta odzola, mafuta amafuta, ndi zina zotero, kutentha kwa nthawi yayitali ndi 120℃, monga momwe mafuta otentha amatha kupirira 150℃, kutentha kochepa ndi -10~-20℃.

  Rabala ya NeopreneNdi yoyenera madzi a m'nyanja, asidi wofooka, alkali wofooka, yankho la mchere, kukana bwino mpweya ndi ozoni kukalamba, kukana mafuta ndi kochepa poyerekeza ndi rabala ya nitrile ndipo ndi bwino kuposa rabala ina yonse, kutentha kwa nthawi yayitali sikupitirira 90℃, kutentha kwakukulu kogwiritsidwa ntchito sikupitirira 130℃, kutentha kochepa ndi -30~-50℃.

Pali mitundu yambiri yarabala ya fluorine, ali ndi kukana bwino kwa asidi, kukana okosijeni ndi kukana mafuta, kukana zosungunulira. Angagwiritsidwe ntchito pafupifupi m'malo onse okhala ndi asidi komanso mafuta ena ndi zosungunulira, kutentha kwa nthawi yayitali komwe kumakhala pansi pa 200℃.

Pepala la rabara ngati gasket yolumikizira, yomwe imagwiritsidwa ntchito kwambiri pa mapaipi kapena mabowo otseguka nthawi zambiri, mabowo amanja, kupanikizika sikupitirira 1.568MPa. Chifukwa m'mitundu yonse ya magasket, magasket a rabara ndi ofewa kwambiri, ogwira ntchito bwino, ndipo amatha kugwira ntchito yotseka pansi pa mphamvu yaying'ono yotsegulira. Chifukwa cha izi, ikapanikizika mkati, imakhala yosavuta kufinyidwa chifukwa cha makulidwe kapena kuuma kochepa kwa gasket.

Pepala la rabara lomwe limagwiritsidwa ntchito mu benzene, ketone, ether ndi zinthu zina zachilengedwe, limatupa mosavuta, limawonjezera kulemera, limamatira mosavuta, zomwe zimapangitsa kuti chisindikizo chisagwire ntchito. Nthawi zambiri, ngati mulingo wa kutupa ukupitirira 30%, sungagwiritsidwe ntchito.

Pankhani ya kuthamanga kochepa (makamaka pansi pa 0.6MPa) ndi vacuum, kugwiritsa ntchito ma rabara pads ndikoyenera kwambiri. Zipangizo za rabara zimakhala ndi kuchuluka kwabwino komanso kutsika kwa kulowa kwa madzi. Mwachitsanzo, rabara ya fluorine ndiyoyenera kwambiri kutseka ma gaskets a zotengera za vacuum, ndipo vacuum digiri ya 1.3×10-7Pa. Rabara pad ikagwiritsidwa ntchito pa vacuum digiri ya 10-1~10-7Pa, imafunika kuphikidwa ndikupopedwa.
