Full o ring seal kit for the Hatsan PCP air rifle hand pump.
Includes all internal o rings required to refurbish or re-seal your airgun pump.
Pack includes sizing chart to match seals up to the exploded diagram on our website.

Please not this is an aftermarket kit with seals exceeding the original spec items – this means they will perform better and last longer.

The final stage seal is high spec grade PU material as this is the most important and operates in the most harsh conditions.
