The two gaskets that provide the seal at the top of the pump housing
on my Zefal Plus Floor Pump are shot. Right now I couldn't inflate
a balloon let alone see 100+ PSI. After visiting several local
bike shops as well as calling the 3rd Hand (mail order parts supply)
I have found that the gaskets are not imported by the U.S. Zefal
distributor. The gaskets (washers) seal the twin pump shafts as
they go through the top of the pump housing and are 1 cm. inner
diameter and 3 cm. outer daimeter and roughly 1/16" thick rubber.
Has anyone else solved this problem and/or have alternative
material suggestions?
Thanks,
Bob

Assuming the gaskets are rubber maybe an old inner tube might be
cut to fit, or maybe one of those thin rubber gaskets used on
trailer lights could be cut up...

The most critical area should be the central hole. Fortunately rubber will stretch so your hole can be a bit under sized. You can cut a smooth hole in rubber with a sharpened piece of tube of the right diameter (or the next smaller size). You can buy brass tube (used for model aeroplane construction) at hobby shops for probably under $1. Spin the tube in a drill and apply a file (to the inside edge if possible) to sharpen the edge. Place the rubber on a wooden block and drive the sharpened pipe through it. | |||||
