200pc Assorted Brass Olives Box - Metric, 4mm to 12mm

200pc Assorted Box of Brass Olives - 200 brass barrel olives for metric compression fittings, in six sizes from 4mm up to 12mm.

The olive sits between the nut and the body of the fitting, and tightening the nut compresses it onto the tube so the joint seals metal to metal without solder, tape or paste. The sizes here cover the smaller tube: microbore heating pipe at 8mm and 10mm, fuel and oil lines, pneumatic and instrument tubing, and the small bore pipework on plant and machinery.
