This is a stainless steel Euro-style band clamp that can be used for 12mm ID fuel supply hoses on FI cars, also on auxiliary air valve hoses. Can also be used on heater hoses and the bottom expansion tank outlet on Fiat X19 and Lancia Scorpion/Montecarlo.
A smooth inner liner will not cut the hose as it clamps.
Range from 12mm - 20mm
New and unused.
