Bore reducers

Require different bore sizes other than straight through bores ? Use our range of bore reducers.

For example, take the BBC100 10mm-10mm model in combination with a BR257-6mm bore reducer, to get the bore combination 10mm-6mm

Bore Reducer Part Number	OD (mm)	L (mm)	Nominal bore to reduce from (mm)	Reduce the nominal bore to one of the reduced bore options below
