The rubber boot provides Accu-gages with a blanket of protection against accidents. A short drop may cause the guage to dent or break. There is a chance to displace its accuracy as well. The rubber boot is a great way to protest your investment. Take care of your guage so it can do its job when called on.

Since auto tire-guages have the potential to be bumped/dropped/etc., this protective boot is clearly worth two bucks. It slips on snuggly and doesn't block meter readings or hinder gauge use in any way. If you own an Accu-Gage, you should get one of these.
