TheISO flange e kholostandard e tsejoa e le LF, LFB, MF kapa ka linako tse ling feela ISO flange. Joalo ka KF-flanges, li-flange li kopantsoe ke selikalikoe se bohareng le lesale la elastomeric. Letlapa le eketsehileng la selikalikoe le nang le selikalikoe hangata le sebelisoa ho pota-pota mehele ea o-diameter e kholo ho thibela hore e se ke ea theoha ho tloha selikalikoe sa centering nakong ea ho kenngoa.

Li-flange tse kholo tsa ISO li tla ka mefuta e 'meli. Li-flange tsa ISO-K (kapa ISO LF) li kopantsoe le li-claw-claw tse peli, tse tlamellang ho groove e chitja ka lehlakoreng la tubing la flange. Li-flange tsa ISO-F (kapa ISO LFB) li na le masoba bakeng sa ho kopanya li-flange tse peli ka liboutu. Li-tubes tse peli tse nang le ISO-K le ISO-F flanges li ka kopanngoa hammoho ka ho tiisa lehlakore la ISO-K ka li-claw tse nang le melapo e le 'ngoe, ebe li tlamelloa mekoting e lehlakoreng la ISO-F.

Li-flange tse kholo tsa ISO li fumaneha ka boholo ho tloha ho 63 ho isa ho 500 mm bophara ba tube ka lebitso.
