Solid Brass Fuel Valve with Chrome plating and 10x1.mm threads. This valve has 3 positions ON/OFF/RESERVE with a 6mm hose fitting. Used on lots of small Italian bikes: Ducati singles, Motobi, Benelli, ETC...  

NOTE:  Most Ducati N/C gas tanks have 10x1.0mm threads but over the years some have been taped out to 12mm, BSP, or American threads. Some small Guzzi & MV singles use the long obsolete 9.5x1.0mm threads. These 10x1.0 petcocks will not fit !! Some of the bikes that use the obsolete 9.5mm threads are Guzzi Stornello, Lodola, Dingo, and Guzzino. MV Tl125, TR125, ETC...

PLEASE MEASURE YOUR EXISTING THREADS BEFORE BUYING !!  SOLD INDIVIDUALLY  !!

We also have these same petcocks available with 12x1.5mm threads in another listing.
