Air Fittings

An air pressure switch tells your compressor when to start and stop, so the tank stays within a set range without you watching it. Pick the range that suits your system:

• 70–100 PSI
• 110–135 PSI
• 110–150 PSI
• 150–180 PSI

Choose a range whose upper limit sits at or below your compressor's working pressure and your tank's rating. The PX02 and PX07 list 0–150 PSI working pressure, the PX01 tops out at 150 PSI, and BOSS aluminum tanks list 0–170 PSI. A switch set inside those limits lets the compressor rest between cycles instead of running against a full tank.

To see what's happening in each air bag, fit the 200 PSI dual-needle gauge. Its two needles show left and right pressure on one dial, and it has a 12V backlight and a 1/4″ NPT connection. It's also sold with fittings included.

For the line between compressor and tank, there's a 700 mm stainless braided hose with 3/8″ flare fittings and a 3/8″ bore.
