Robinair R134a Aluminum Manifold Kit 49134A — Blue Anodized, 3 Hoses & 90° Couplers in Case

Robinair 49134A is a complete aluminum manifold, gauge, hose and coupler kit engineered for diagnosing and servicing R‑134a refrigeration systems.

This compact service set brings a shop‑grade manifold assembly in a durable blow‑mold case so technicians and experienced DIYers can read pressures, perform evacuations and connect refrigerant lines quickly. The anodized aluminum manifold pairs with color‑coded gauges and five‑foot hoses to keep installations organized, while internal passages ensure vacuum and pressure monitoring regardless of valve position. The package focuses on usability, corrosion resistance and service versatility for automotive and small HVAC‑R work.

How does the Robinair 49134A manifold measure pressures reliably?

The manifold uses isolated passages from each service port to its corresponding gauge so you still get accurate pressure and vacuum readings whether the handwheels are open or closed. Blue and red color coding makes low‑side and high‑side identification immediate, and brass fittings resist corrosion where hose and coupler meet the manifold. Gauges are positioned for quick visual checks during charging, recovery or leak tracing.

• Separate internal passages for low and high side gauge accuracy
• Blue compound gauge on the low side, red pressure gauge on the high side
• Brass fittings at hose connections for durability
• Handwheels and gauges color‑matched for fast identification

What components are included and how do they simplify service tasks?

The kit ships with a blue anodized aluminum manifold body, two color‑coded gauges, three 60‑inch hoses, 90° manual service couplers and a blow‑molded case. Long hoses give extra reach around engine bays or rooftop units, while the 90° couplers ease access to service ports in tight locations. The case organizes the set so technicians can store and transport it without losing small parts.

• 1x blue anodized aluminum manifold with three lower fittings
• 2x color‑coded gauges (low side compound, high side pressure)
• 3x 60-inch (5 ft) hoses for extended reach
• 3x color‑coded 90° manual couplers and a molded storage case

How does this set perform in everyday workshop or field use?

Designed for frequent use, the aluminum manifold balances lightweight handling with resistance to corrosion. Long hoses and right‑angle couplers reduce strain when connecting to awkward service ports, and the case protects gauges and hoses from impacts during transport. The internal manifold layout helps technicians monitor vacuum and pressure changes continuously while performing charging and evacuation steps.

• Lightweight aluminum manifold for easier handling during service
• Five‑foot hoses reduce need for extensions and improve maneuverability
• Sturdy blow‑molded case keeps components organized and protected
• 90° couplers allow access in confined spaces without hose kinking

What refrigerant systems is the 49134A compatible with?

This Robinair set is configured specifically for R‑134a service work, the refrigerant commonly found in many automotive and small refrigeration systems. It is optimized for the pressures and servicing practices associated with R‑134a; check system requirements and local regulations before use. The kit is not intended to substitute for manifold sets designed for other refrigerants without proper adapters and verification.

• Factory setup for R‑134a refrigerant systems
• Suitable for automotive A/C and small HVAC‑R service tasks
• Not a direct substitute for other refrigerant types without adapters

Who is this for? The Robinair 49134A kit is aimed at professional technicians, mobile service techs and skilled DIYers who perform routine diagnostics, evacuations and refrigerant charging on R‑134a systems. If you need a portable, reliable manifold set with long hoses, color‑coded gauges and a protective case for frequent field or shop use, this kit provides the core tools required for safe, efficient service.
