The Yellow Jacket 49137 is a 3-1/8 inch diameter pressure gauge designed for accurate high-side pressure measurement in HVAC/R systems. Featuring a 1% accuracy rating (ANSI Grade 1), this gauge is built for field reliability and diagnostic precision. It includes a full-view polycarbonate crystal lens, a front recalibration screw, and a durable steel case for use in demanding service conditions.
Suitable for use with manifold gauge sets or direct system mounting, the 49137 is color-coded red for high-pressure applications and includes easy-to-read R-22, R-404A, R-410A, and R-134a temperature scales. The gauge is equipped with a standard 1/8" NPT male connection and supports recalibration in the field.
This gauge is compatible with standard Yellow Jacket manifold bodies and other assemblies using 1/8" NPT fittings. Calibration should be verified periodically, especially in high-cycle service environments. The polycarbonate lens and steel case provide protection from impact and environmental wear, but exposure to extreme temperatures or chemical agents should be avoided to maintain accuracy.
The Yellow Jacket 49137 is engineered for precision and durability in HVAC service environments. With a broad pressure range, multiple refrigerant compatibility, and ANSI Class 1 calibration, this gauge supports accurate system monitoring and diagnostics. Built for long-term reliability with field-serviceable recalibration.
