Wolverine STORM On-Tank Regulator Base Assembly

The base is the half that screws into the tank valve, which makes it the component most exposed to cross-threading, over-tightening and the general abuse of being removed and refitted in a safe zone. It is also what seals against the valve, so damage there shows up as a leak you cannot tune out.

Replacing the base rather than the whole regulator keeps the expensive part of the assembly in service. Wolverine supply it as an assembly rather than a bare machining, so it arrives ready to fit.

Note which generation you have. This is the legacy on-tank base; the current STORM Category 5 regulator uses a different base, which we list on its own.

Specifications

Good to know before you buy

Check the tank valve while you are at it. A base that failed because of a damaged valve seat will fail again, and that is a cheaper thing to find now than after fitting.

There is an aftermarket option too. We stock a Kross replacement for the same legacy base, so it is worth comparing before you commit.

Frequently asked questions

How do I know the base is the problem?
A leak at the tank joint that persists after the o-rings have been changed usually means the base sealing face or thread is damaged.

Will it fit the Category 5?
No. The Cat 5 has its own base, which is a separate listing.

Do I need any other parts with it?
Not necessarily, but fresh seals are sensible. If the internals are also tired, those are listed separately.

Can I fit it myself?
It is a straightforward swap with the right tools. If you would rather not, our HPA tech service can do it and pressure-test the result.
