Irabha yemveloifanele amanzi, amanzi olwandle, umoya, igesi engasebenzi, i-alkali, isixazululo samanzi sikasawoti kanye nezinye izinto, kodwa ayimelani namafutha amaminerali kanye nezinyibilikisi ezingezona ezi-polar, izinga lokushisa lokusetshenziswa isikhathi eside alidluli ku-90℃, ukusebenza kwezinga lokushisa eliphansi kuhle kakhulu, lingasetshenziswa ngaphezu kuka-60℃.

  Irabha ye-Nitrileifanele imikhiqizo kaphethiloli, njengophethiloli, uwoyela wokugcoba, uwoyela kaphethiloli, njll., izinga lokushisa lokusetshenziswa isikhathi eside lingu-120℃, njengakuwoyela oshisayo ongamelana no-150℃, izinga lokushisa eliphansi lingu-10~-20℃.

  Irabha ye-Neopreneifanele amanzi olwandle, i-asidi ebuthakathaka, i-alkali ebuthakathaka, isixazululo sikasawoti, ukumelana okuhle kakhulu nomoya-mpilo nokuguga kwe-ozone, ukumelana kwamafutha kungaphansi kwerabha ye-nitrile futhi kungcono kunenye irabha evamile, izinga lokushisa lokusetshenziswa isikhathi eside lingaphansi kuka-90℃, izinga lokushisa eliphezulu lokusetshenziswa alidluli ku-130℃, izinga lokushisa eliphansi lingu-30~-50℃.

Kunezinhlobo eziningi zeirabha ye-fluorine, zinokumelana okuhle kwe-asidi, ukumelana nokushiswa kwe-oxidation kanye nokumelana namafutha, ukumelana nokuncibilikisa. Zingasetshenziswa cishe kuzo zonke imidiya ye-asidi kanye namafutha athile kanye nezincibilikisi, izinga lokushisa lokusetshenziswa isikhathi eside lingaphansi kuka-200℃.

Ishidi lerabha njenge-flange gasket, esetshenziswa kakhulu kumapayipi noma ama-manholes avame ukuhlakazwa, imigodi yesandla, ingcindezi ayidluli i-1.568MPa. Ngoba kuzo zonke izinhlobo zama-gasket, ama-gasket erabha alula kakhulu, asebenza kahle ekubopheni, futhi angadlala umphumela wokuvala ngaphansi kwamandla amancane okulayisha ngaphambi kokulayisha. Ngenxa yalokhu, uma icindezelwa ngaphakathi, kulula ukuyicindezela ngenxa yobukhulu noma ubulukhuni obuphansi be-gasket.

Ishidi lerabha elisetshenziswa ku-benzene, i-ketone, i-ether nezinye izinyibilikisi eziphilayo, kulula ukulibona livuvukala, liyanda isisindo, lithambile, linamathela, okuholela ekuhlulekeni kokuvala. Ngokuvamile, uma izinga lokuvuvukala lidlula u-30%, alikwazi ukusetshenziswa.

Uma umfutho ophansi (ikakhulukazi ngaphansi kuka-0.6MPa) kanye ne-vacuum, ukusetshenziswa kwama-raber pads kufaneleka kakhulu. Izinto zerabha zinobukhulu obuhle kanye nokuvuleka okuphansi. Isibonelo, irabha ye-fluorine ifaneleka kakhulu ekuvaleni ama-gasket ezitsheni ze-vacuum, kanti izinga le-vacuum lifinyelela ku-1.3×10-7Pa. Uma i-raber pad isetshenziswa ku-vacuum degree range engu-10-1~10-7Pa, idinga ukubhakwa nokupompiwa.
