Ondrives offer a range of brass and aluminium bore reducers designed to fit into couplings where smaller bores are required quickly and easily.

They start at size 5mm O/D and go up to 28mm O/D, the smallest bore available being 2mm in brass and the largest 25.4mm in aluminium. It should be noted that both concentricity and traction may be affected when using a bore reducer, so customers are advised to check their application carefully before using.

Ondrives technical staff are on hand at all times to offer their assistance if you need any help or advice on using these parts.
