Yellow Jacket AC Gauges 3-Way Manifold Set with 5ft Hoses (R134a/R12/R22/R502)

Overview

Meet the Yellow Jacket AC Gauges 3-Way Manifold Set, a compact, durable kit designed for automotive A/C service. Whether you’re diagnosing a sluggish cooling system on a hot day or topping up refrigerant during a roadside repair, this gauge set provides clear readings and dependable function without complicating your workflow. The 3‑way design lets you observe system status while you evacuate, recharge, or survey performance under real conditions.

What’s included and how it helps

The centerpiece is a robust three‑way manifold paired with three color‑coded hoses so you can quickly distinguish low, high, and charging lines. You’ll also receive two adjustable 1/4" quick couplers, a 1/4" to 1/2" SAE adapter, and a self‑sealing can tap. Before you operate, check the opening valve to confirm compatibility and a tight seal.

• Three‑way manifold with a moisture indicator for real‑time coolant condition.
• Blue low‑pressure, red high‑pressure, and yellow charging hoses, each built for daily HVAC tasks at up to 500 psi.

The kit is compatible with several common refrigerants: R134a, R12, R22, and R502. This broad support helps you measure pressures, evacuate air, and refill refrigerant as needed, supporting multiple job scenarios from quick checks to full recharge cycles.

Real‑life use cases

Imagine working on a vehicle with tight service ports; the 5 ft hoses give you reach without stretching or moving the unit repeatedly. In a shop, the included adapters and couplers simplify connections across different fittings. The humidity/moisture indicators help you gauge whether refrigerant quality is suitable for charging or if a subsequent evacuation is advisable.

• Diagnose pressure imbalances on R134a, R12, R22, or R502 systems during routine service.
• Evacuate moisture and air to prepare a system for an efficient recharge.

Care and use tips: follow the valve guidelines to ensure a secure seal, avoid overtightening, and store the set where hoses won’t kink. The durable construction and flexible hoses are designed to withstand regular maintenance tasks while providing clear, actionable readings to guide your workflow.

Designed for both DIY enthusiasts and professional technicians, the Yellow Jacket set blends accuracy with practicality. Color‑coded hoses reduce cross‑connection errors, while the self‑sealing can tap minimizes leak risk during can tapping. The rugged fittings and reinforced hoses stay flexible across temperature changes, ready for daily shop life.
