Iityhubhu ezikhethekileyo zokucutha ubushushu zizinto ezikhethekileyo kunye nosetyenziso olukhethekileyo lwetyhubhu ecutha ubushushu, ibandakanya i-tubing engatyibilikiyo eyenziwe ngobushushu, i-pvdf heat shrink tubing, ptfe teflon heat shrink tubing, i-viton heat shrink tubing, i-rubber ye-silicone yokunciphisa ubushushu, i-epdm irabha iyancipha i-tubing idizili ekwaziyo ukumelana nobushushu belastomeric icutha iityhubhu. Imisebenzi yale mibhobho nayo yahlukile, eminye isetyenziselwa ngokukodwa ukukhusela isibambo sezixhobo zokuloba, ezinye zisetyenziswa kwiindawo ezifuna ukhuseleko oluphezulu lobushushu, kwaye ezinye zifuna ukuxhathisa ioli kunye neekhemikhali.
Iityhubhu ezahlukeneyo zinokukhethwa ngokwezicelo ezahlukeneyo kunye neemfuno.
