The Mastercool EBL1 80 mm low-side gauge gives licensed techs clean, repeatable readings on R22/R407C/R32/R410A systems. It’s Class 1 accuracy, chrome-plated and built with anti-flutter movement — fair dinkum upgrade for fogged or knocked dials.

Key features & trade benefits

• Class 1 accuracy, 80 mm face — faster diagnostics at a glance; fewer misreads on hot rooftops.
• Anti-flutter movement — steadier needle = more precise charging and fewer call-backs.
• 1/8″ NPT back mount — quick swap into most analogue manifolds; back on the tools in minutes.
• Chrome-plated housing — added protection from knocks and day-to-day wear.
• R22/R407C/R32/R410A scales — pressure/temperature saturation scales right on the face for quick checks.

Why this product matters

Real-world: you’re on a Sydney roof, wind howling, customer watching. Your old LP dial’s sticky. Swap in the EBL1 and those numbers settle straight away — no worries about overcharging or second-guessing the superheat. If you’re refreshing a whole set, see our Mastercool Manifold Gauge Sets.

Pro tip

Zero the pointer before connecting. When installing into the manifold, apply suitable thread sealant on the 1/8″ NPT, finger-tight then nip up — don’t over-torque. Add a rubber boot for extra lens protection — she’ll be right.
