Not ideal for some pumps

  • Familiarity:I've put it through the wringer

I've found that some pumps can not lock on as well as others. I've had numerous problems reaching as low as 22lbs.

These are perfect, with a removable core and included tool to take it out, you can add fluid without making a mess. You can also add air way quicker with a blowgun from a compressor, to instantly seat and seal. No leaks or complaints.
