Yellow Jacket 49137 Pressure Gauge – 3-1/8″ Dial, Red, Class 1, High-Pressure (0–800 PSI) for HVAC/R Manifolds

Yellow Jacket 49137 Pressure Gauge – 3-1/8″ Dial, Red, Class 1, High-Pressure (0–800 PSI) for HVAC/R Manifolds

Condition: Used. Moderate cosmetic wear; needle moves freely and dial face is legible. No cracks or major damage.

The Yellow Jacket 49137 is a Class 1 high-pressure HVAC/R gauge with a 3-1/8″ dial face, part of Yellow Jacket’s premium manifold and diagnostic series. Designed for accurate pressure readings in refrigerant systems, this model features a red dial face, typically indicating its use for high-side (discharge) pressure measurement. It reads from 0 to 800 PSI, making it suitable for modern refrigerants, including R-410A, R-22, and R-404A, commonly used in residential, commercial, and industrial air conditioning and refrigeration systems.
The Class 1 accuracy rating ensures ±1% full-scale precision, meeting ANSI standards for critical servicing tasks. This gauge is compatible with most Yellow Jacket manifolds as well as third-party gauge sets using a 1/8″ NPT back or bottom mount.
