- description
Gauges live on the outside of the regulator, which is exactly where a rifle gets dropped, leaned against things and thrown into a car boot. A cracked gauge is one of the most common HPA repairs there is, and one of the least serious — provided you can get the part.
Running without one is worse than it sounds. The gauge is how you know what pressure the engine is actually receiving, which is how you stay inside your site limit. Guessing is not a strategy when a marshal is holding a chronograph.
This is the 0–220 PSI replacement with a 25mm face, covering the working range of standard airsoft HPA setups.

Good to know before you buy
Check the thread and face size against your existing gauge before ordering — regulators vary between manufacturers even where the pressure range matches.
Always depressurise the system fully before removing a gauge. If you are unsure, bring it to us.
Frequently asked questions
Will it fit my regulator?
It is the PolarStar replacement at 0–220 PSI with a 25mm face. Check thread and size against yours, or send us a photo and we will confirm.
Can I run without a gauge?
You can, but you should not. It is how you know the pressure reaching your engine, and therefore how you stay inside your site limit.
Is it hard to replace?
No, but the system must be fully depressurised first. We are happy to do it if you would rather not.
Why do they break so often?
They sit on the outside of the regulator and take every knock the gun does. It is the most exposed part of an HPA setup.
