What Deb said x99! Borg Valves, Air-Through Caps (come with some kits, available at NAPA on their carousel displays) and air checking becomes:
1. Easy since all I need is ANY Gauge, ANY Air Hose and don't even have to remove the Caps.
2. Fun since those great valves pretty much eliminate air loss.
We have the absurd 10-hole wheels Ford supplied on RV chassis for years (commercial customers like U-Haul wouldn't tolerate them) and Dicor Simulators (innies) that make for really small, sharp, access holes. Borg valves stick right out, right where they should, stay put to check.
I used to rant like Ed did. No more!
