Spare Parts & Maintenance

Keeping a PCP running

Most of what wears out on a PCP is small and cheap. Valve pins take a beating on semi-autos, gauges fog or drift, and seals give up long before anything expensive does. Keeping a couple of the right parts on the shelf is most of what PCP maintenance amounts to, and it's the difference between a quiet evening and a lost weekend.

If the rifle is losing air overnight, work from the outside in. Start at the fill port and the probe O-ring, which sits behind most slow leaks, then the burst disc, then the valve. A burst disc is a safety part, so replace one that's blown and never plug it or shoot the gun without it.

Everything here is cut for a specific model, so check the caliber and the generation in the listing before you order, because both change what actually fits. Run the same check on the gun at the start of the season, after it's been sitting. Fill it, leave it a day, and see where the needle ended up.
