If you work on diesel engines, this Milton compression tester is a must-have tool. It reads from 0 to 1000 PSI (or 0-7000 kPa) with a clear, easy-to-read dial gauge. The built-in release valve lets you vent pressure instantly, making tests quicker and safer. It’s designed specifically for diesel applications—don’t use a standard valve core with this one. Made right here in the USA, Milton’s been making quality air and diagnostic tools since 1943. Perfect for mechanics, fleet maintenance, or serious DIYers who need accurate compression readings to diagnose engine problems. Reliable, durable, and simple to use—exactly what you want from a professional-grade tester.
