AN INDUSTRY FIRST!
Single Handed Operation To 12,000 PSI
The Macnaught AutoSwitch™ is built to take on the toughest jobs with ease. Delivering up to 12,000 PSI through its patented dual-piston design, it automatically switches from high-flow to high-pressure the moment resistance is detected. That means no strain, no interruptions, and no wasted effort — just smarter, safer, one-handed greasing that lets you get the job done without breaking a sweat.

Key Features
Automatic Switching
Boost productivity instantly. AutoSwitch™ eliminates manual mode changes by automatically shifting from high-flow to high-pressure the moment resistance is detected — powering through blocked fittings and delivering up to 12,000 PSI for faster, smoother, uninterrupted greasing.

Blue Pin Indicator
Work smarter with instant clarity. The Blue Pin pops to show when high-pressure mode activates, giving you quick visual confirmation so you can tackle tough fittings with confidence and keep your workflow moving without hesitation.


Flexible High-Pressure
Extension Hose
Reach every fitting with ease. The high-pressure flexible hose helps you get to hard-to-access spots eliminating the frustration of missed or impossible grease points.
Q-Lock System
Stay clean and in control. The Q-Lock provides a fast, secure, leak-free connection that stops drips, prevents mess and saves time on cleanup.
