The Arundel CNC Nugget is a compact shop inflator that connects to air compressor lines for inflating Presta valve tires. The body is CNC-machined from 6061 aluminum with cross-drilled internal air passages. This design routes air through a valve plunger that measures tire pressure directly rather than showing the pressure in your compressor line. You're reading what's actually in the tire, not what's coming through the hose—makes it easier to hit target pressures without overshooting or having to bleed air back out.

The digital gauge is a two-inch display with backlighting. You can read it in dim garage lighting or basement workshops without squinting. The gauge runs on CR2032 batteries, which are standard coin cells you can pick up anywhere. Battery access is straightforward when it's time to replace them. The backlighting activates when you need it, helping with visibility in low-light work areas. The inflator connects to compressor lines using a quarter-inch I/M fitting, which is the standard size on most home compressors and pneumatic tools. No adapters or special fittings required if your setup uses standard connectors.

The Woodsman pump head handles Presta valves only—this isn't a dual-valve tool. If you need Schrader compatibility, Arundel makes a separate version for that. The Presta-specific design keeps the head compact and eliminates the swapping or flipping required by dual-valve systems. You press it onto the valve stem and it seals. No threading, no fumbling with adapters.... Read More
