I want to know the corny's pressure of the regulator so I was going to buy one of these:-

Then I thought, I've got a guest, push fit, gas pipe fitting and a motorbike tyre pressure tester. I took the valve head of the testers rubber tubing and pushed the tubing into the guest fitting and hey presto a corny pressure tester.


A different take on this.... a standard foot tyre inflator clamps onto a tyre valve.
If you have a barb fitting on your disconnect, the tyre inflator will clamp directly onto this B)
The benefit of the motorbike tester is that you can release pressure to the desired level with a little button on the side of the gauge head.
