Description
Daystate HUMA Regulator Seal Kit
Rebuild kit of O-rings and grease for all Huma-Air equipped models
The factory-genuine Daystate HUMA-AIR Regulator Seal Kit fits all Daystate PCP models that use this particular system. It can be used to routinely service the regulator. Kits are specific to model type – see ‘Compatibility’ below.
What’s in this Kit
This air regulator service kit includes two sets of reg piston O-ring seals. Additionally, it comes with with a syringe containing the correct grade of silicone grease. This is used for lubricating the Huma-Air regulator’s internal parts.
Compatibility
There is no ‘one-size-fits-all’ seal kit as regulated Daystate PCP air rifle models use slightly different regulators according to model type. So, when you order this genuine factory replacement for your Daystate PCP, we need as much detail as possible. This will help the factory identify the correct kit suitable for your rifle.
Note: This kit contains regulator seals only. You will need different seals to service other parts of your rifle, eg: breech o-rings and general o-rings
IMPORTANT: This kit is suitable for Huma-Air Regulators only. It is not suitable for servicing Daystate’s regulated CR or MK3 PCP models. These require special adaptors and are not user serviceable; for these, you will need to contact your nearest authorised Daystate Service Agent.
Fitting
We know that many shooters prefer to service their own equipment. So, we have produced comprehensive instructions for stripping and servicing regulators (et al) in our Workshop Guides. Additionally, you can watch our detailed video on regulator seal replacement and adjustment on our official YouTube channel.
However, stripping precharged pneumatic air rifles is dangerous and you should not attempt to do this unless you are suitably qualified to do so. We therefore highly recommend that you have your Daystate PCP serviced by an authorised Daystate Service Agent.
