SOLD Bought this new from CNC Machines several years ago. Works great and is in excellent condition.
This device allows you to fill both front tires to the same pressure. This is the high pressure model and can be used (judiciously) with any compressor.
Asking $50, shipping via USPS Priority Mail included. Prefer payment by Zelle, but will accept payment by check (package will be shipped as soon as check clears).
