I found POK guide on the hw owners forum really useful and sourcing your own seals according to those dimensions cheaper and more effective. Only had to do it once and no problems since. Glad to hear you cracked it

I use the HW100 Tuning seal packs, all are the correct sizes, excellent quality, individually marked up and very reasonably priced.

Not had one leak yet and I've serviced a fair few HW100's now, I'm in my fourth this week!

I agree the Hw100 tuning o-rings and other products are very good.

A relative bought a seal kit for an S200 that were supposed to be the right size etc. I think that they were off the Evil Bay. Turned out that one of the seals was completely wrong. I think part of the problems is that some sellers may not be aware of the various different changes to airguns through their production life, such as the different fill valves on s200s of different ages/marks.
The moral of the story, I'm sure, is to buy seals and o-rings from reputable suppliers, even if they aren't the cheapest.

I've had poor kits off Knibbs for a couple of guns I've been fixing but for £5 you can't beat the HW100 Tuning minor service kit, I've never had a problem with any of their products. The O ring kits cover every eventuality and every variant, I fit them in all the guns I service and that's a fair few now.
