Ketron Peek Helix Rod

This compatable MB helix rod is manufactured from a plastic material called 'Peek' which is a much stronger alternative to conventional plastics.

This rod has a circular cross section which gives it the merit of being a stronger alternative to the injection moulded version which has a reduced oval cross section currently in use

It uses the same end design and is fully compatible with both the 146 and 149 pens

As with all pen repairs some knowledge of fitting spare parts is desirable.

Please have a look at the www.fountainpennetwork.com links below which is a forum entry written by a renowned user of my parts. On the thread this part is given a rigourous testing and appraisal which I am sure you will find informative.
