Yellow Jacket Manifold Gauge 49117 A2L Red 3-1/8″ for R-32 R-410A

Description

Product Overview

The Yellow Jacket 49117 A2L Manifold Gauge is engineered for demanding HVAC applications where precision, durability, and ease of use are paramount. Constructed from high‑grade brass, the gauge housing resists corrosion and provides a solid, tactile feel that professionals trust in the field. The 3‑1/8″ (80 mm) dial face offers a clear, easy‑to‑read display, while the red‑colored housing not only adds visual distinction but also enhances visibility in low‑light environments. Calibrated to within 1 % accuracy, the gauge delivers reliable pressure measurements across a 0‑500 PSI range, making it suitable for a wide variety of refrigerant cycles. Integrated flutterless technology, combined with a brass surge protector, significantly reduces needle pulsation, ensuring a steady reading even under rapid pressure changes. The gauge is compatible with R‑32, R‑454B, and R‑410A refrigerants, covering the most common modern HVAC refrigerants and providing flexibility for technicians working on multiple system types.

Usage

Designed for both residential and commercial HVAC service technicians, this manifold gauge excels in a range of real‑world scenarios. Whether you are charging a new air‑conditioning system, diagnosing a pressure drop in an existing loop, or performing routine maintenance on a heat pump, the gauge offers the accuracy and responsiveness required for effective troubleshooting. Its compact dimensions (7 × 5 × 1 inches) and lightweight design (7.05 oz) allow it to be easily carried in a tool bag or mounted on a service cart, reducing fatigue during long service calls. The gauge’s Fahrenheit scale aligns with standard HVAC temperature readings, streamlining the workflow for technicians who need to correlate pressure and temperature data quickly. Additionally, the robust construction ensures reliable performance in harsh environments, including outdoor installations where exposure to dust, moisture, and temperature extremes is common.
