The non-return valve (NRV) at the bottom of the pump tube can often leak when the rubber or cork pip inside hardens. We sell pips for these valves however many valves feaure a shaped pip which fit's directly to the spring. This was a cost saving measure over the style that feature a brass holder for the pip.
What we offer here is the brass holder to service & convert your original vintage valve, keeping as much of it original as possible. The holder also includes a VITON pip.
