Meet the PB Motor Tech BMT AC Diagnostic Manifold Gauge Set, a practical companion for automotive and residential air conditioning maintenance. Designed for durability and precise readings, this kit blends solid metal construction with user-friendly features that help you assess refrigerant flow and pressure with clarity. Whether you’re a DIYer or a professional, the setup invites confident work and easy interpretation of results across common systems.

Durable design that withstands regular use

The manifold gauge is built from sturdy metal, delivering a balanced combination of strength and lightness. The rugged body resists daily wear while remaining easy to carry between jobs. A sight glass window helps you verify refrigerant levels at a glance, and the extra-large, rubber-coated dials stay readable even in busy shop environments or dim garages.

What you get in the complete set

• Three-way gauge for concurrent readings and monitoring
• Three color-coded hoses for high, low, and charging lines
• Two 1/4" straight quick couplers for quick, secure connections

Clear readouts and practical design

The large dials are easy to interpret, while the rubber coating provides a comfortable grip and helps protect the gauge from bumps. The color-coded hoses reduce setup time by helping you quickly identify the right line during installation or diagnosis, which is especially helpful when working with multiple components in tight spaces.

Versatility across refrigerants and applications

Designed to work with common refrigerants such as R134A, R12, R22, and R502, this set offers broad compatibility for automotive and domestic air conditioning maintenance. With a 500 psi working pressure and a 2500 psi burst pressure, it provides a practical safety margin for typical servicing tasks without being overbuilt for lighter jobs.

How this set supports your workflow

Whether you’re diagnosing a cooling issue in a car, servicing a window unit, or maintaining a split-system at home, this gauge set helps you approach tasks with clearer readings and fewer guesswork moments. The portable design makes it suitable for the driveway, a small shop, or storage in a garage cabinet, so you can keep it handy when AC maintenance season hits.
