Irabha yendaloifanelekile emanzini, emanzini olwandle, emoyeni, kwigesi engasebenziyo, kwi-alkali, kwisisombululo samanzi setyuwa nakwezinye izinto, kodwa ayixhathisi kwioyile yeminerali nakwizinyibilikisi ezingezizo ze-polar, ubushushu bokusetyenziswa ixesha elide abudluli kwi-90℃, ukusebenza kobushushu obuphantsi kugqwesile, ingasetyenziswa ngaphezulu kwe--60℃.

  Irabha yeNitrileifanelekile kwiimveliso zepetroleum, ezifana nepetroleum, ioyile yokuthambisa, ioyile yepetroli, njl., ubushushu bokusetyenziswa ixesha elide yi-120℃, njengokuba kwioyile eshushu inokumelana ne-150℃, ubushushu obuphantsi yi--10~-20℃.

  Irabha yeNeopreneifanelekile kumanzi olwandle, i-asidi ebuthathaka, i-alkali ebuthathaka, isisombululo setyuwa, ukumelana okuhle kakhulu neoksijini kunye nokuguga kwe-ozone, ukumelana neoyile kungaphantsi kunerabha ye-nitrile kwaye kungcono kunezinye irabha eziqhelekileyo, ubushushu bokusetyenziswa ixesha elide bungaphantsi kwama-90℃, ubushushu bokusetyenziswa obuphezulu abudluli kwi-130℃, ubushushu obuphantsi buyi-30~-50℃.

Kukho iintlobo ezininzi zeirabha yefluorine, zinokumelana okuhle kwe-asidi, ukumelana ne-oxidation kunye nokumelana neoyile, ukumelana nesinyibilikisi. Zingasetyenziswa phantse kuzo zonke iindawo ze-asidi kunye nezinye iioyile kunye nezinyibilikisi, ubushushu obusetyenziswa ixesha elide bungaphantsi kwama-200℃.

Iphepha lerabha njenge-flange gasket, esetyenziswa kakhulu kwiipayipi okanye kwiindawo zokuchitha amanzi ezidla ngokuqhekeka, imingxuma yesandla, uxinzelelo aludluli kwi-1.568MPa. Kuba kuzo zonke iintlobo zee-gasket, ii-gasket zerabha zezona zithambileyo, zisebenza kakuhle ekubopheni, kwaye zinokudlala isiphumo sokutywina phantsi kwamandla amancinci okulayisha kwangaphambili. Ngenxa yoku, xa iphantsi koxinzelelo lwangaphakathi, kulula ukuyicinezela ngenxa yobukhulu okanye ubunzima obuphantsi be-gasket.

Iphepha lerabha elisetyenziswa kwi-benzene, i-ketone, i-ether kunye nezinye izinyibilikisi zendalo, kulula ukulibona lidumba, liyanda ubunzima, lithambile, linamathela, nto leyo ebangela ukungasebenzi kakuhle kwetywina. Ngokubanzi, ukuba inqanaba lokudumba lidlula i-30%, alinakusetyenziswa.

Kwimeko yoxinzelelo oluphantsi (ingakumbi ngaphantsi kwe-0.6MPa) kunye ne-vacuum, ukusetyenziswa kwee-raber pads kufanelekile ngakumbi. Izinto zerabha zinobunzima obuhle kwaye zingena kancinci. Umzekelo, irabha ye-fluorine ifanelekile kakhulu ekuvaleni ii-gaskets zezikhongozeli ze-vacuum, kwaye i-vacuum degree ifikelela kwi-1.3×10-7Pa. Xa i-raber pad isetyenziswa kuluhlu lwe-vacuum degree lwe-10-1~10-7Pa, kufuneka ibhakwe kwaye ipompe.
