Our Snap-It Apogee head is made in accordance with the valve standard 4.5 to 5 mm.
It may be that the depth of your valve does not follow up this standard?
If this is the case, it will be advisable to use our valve extender for the best solution.
We would like to make sure if the problem comes from the hose or gauge.
Can you please follow up the stage as the below:
Test 1 to see if the problem comes from the hose:
Disassemble the hose from the pump and see if the air still comes back to the pump.
If the problem fixed,
I think this will be most efficient to contact with our local distributor to get the gauge for the replacement.
We could not make sure our hose and Snap-It are compatible with your pump due to the different specifications.
It will be strong advisable to buy the entire pump of Birzman pump.
