BSA HuMa Regulator Service Kits

XTX Air
KIT REG

These are replacement O rings for the BSA HuMa regulator, like the normal BSA, Ultra SE, Scorpion SE, R-10 etc. Handy for when you want to carry out a basic service of your HuMa regulator. It is also a good idea to keep a set in your gun bag in case you develop a leak in the field.

R-10: The set contains:

BSA: The set contains:

  • 1 x large main body O ring,
  • 1 x small piston O ring,
  • 1 x large piston O ring,
  • 1 x adjuster O ring.
  • Service video

BSA SE: The set contains:

  • 4 x main body O rings,
  • 1 x small piston O ring,
  • 1 x large piston O ring,
  • 1 x adjuster O ring,
  • Service video

They are black nitrile (rubber) O rings.

I don't sell O rings for the actual original BSA regulators because I don't support them, I supply seals for the HuMa and Tench regulators, which are a much better product.

The photo is a generic picture of some O rings, not the actual O rings you will receive.
