Onoto 7.78mm Repair Pack

Suitable for the 1000, 2000, 3000, and 3500 type pens this washer is  7.78mm diameter

The kit contains 1 x seal and 3 x cork gaskets, a backing washer and a fixing pin with a diameter of 1.2mm to secure the plunger assembly after replacing the seal

In order to minimise cracking of the cork when handling, the corks have been impregnated with medical grade paraffin wax which lubricates the surface and helps the plunger rod slide easily while maintaining a seal.

An optional Cork removal/Pick tool is available to assist in the removal of the old corks
