BACOENG AC Manifold Gauge Set for R32 & R410A — 5ft Hoses, Brass Fittings, Sight Glass

The BACOENG AC Gauge Set is a complete HVAC manifold kit built for charging and diagnosing R32 and R410A air conditioning systems with clear dials, durable brass fittings, and 5-foot hoses.

This BACOENG manifold gauge set gives technicians and DIYers a straightforward, durable tool for servicing residential and light commercial A/C systems that use R32 or R410A refrigerants. It excludes automobile R134a quick couplers, so it’s intended for stationary HVAC applications. The set combines two large, color-coded gauges, a three-way manifold body, three high-quality rubber hoses, and two adapters to simplify refrigerant charging and pressure checks.

How does the BACOENG set help me check system pressures?

The kit’s oversized, color-coded dials make it easy to read low- and high-side pressures at a glance. Gauges are marked in psi (red up to 760 psi; blue up to 550 psi) and include a sight glass to confirm refrigerant flow while charging.

• Large colored gauges for quick pressure confirmation.
• High-side (red) up to 760 psi, low-side (blue) up to 550 psi.
• Sight glass for visual verification of refrigerant movement.
• Fahrenheit scale for compatibility with common HVAC readings.

Can I use this kit for automotive air conditioning?

No — this kit does not include R134a quick couplers needed for most vehicle systems. It is tailored for stationary HVAC systems that use R32 or R410A; automotive technicians should add the separate auto service kit or buy BACOENG’s dedicated vehicle kit.

• Not compatible with automotive R134a quick couplers out of the box.
• Designed for home and commercial HVAC refrigerants R32 and R410A.
• Optional auto adapters can be purchased separately if needed.

What materials and components are included, and how reliable are they?

The manifold body uses robust materials and the connectors are brass to resist corrosion and wear. Hoses are made from quality rubber with gaskets to minimize leakage, while the kit ships with two 5/16" male to 1/4" female adapters so you can reach common service ports.

• Durable brass fittings for long-term reliability.
• High-quality rubber hoses with leak-resistant gaskets.
• Three-way gauge manifold for standard HVAC procedures.
• Includes two 5/16" male to 1/4" female adapters for compatibility.

How do the sight glass and hoses improve charging accuracy?

The integrated sight glass lets you visually confirm refrigerant flow and detect moisture or bubbles during charging, which helps prevent overcharging and ensures smoother system operation. The 5-foot hoses give enough reach to work safely around outdoor units and tight service panels without straining connections.

• Sight glass highlights refrigerant flow and potential contaminants.
• Five-foot hoses provide safe reach and flexible positioning.
• Gasketed connections reduce leak risk during charging.

Who this is for: HVAC professionals, service technicians, and experienced DIY homeowners who need a focused tool for R32 and R410A systems will get the most value from the BACOENG AC Gauge Set. If you work on stationary air conditioning equipment and want large, easy-to-read gauges, solid brass fittings, and a sight glass for charging verification, this kit is a practical, cost-conscious choice. Note that automotive R134a servicing requires additional couplers or a different kit.
