BACOENG AC Manifold Gauge Set R1234yf/R134a — 4‑Way Kit with 5ft Hoses, Brass Fittings

The BACOENG AC R1234YF Gauge Set is a complete four‑way manifold kit designed for charging, evacuating and diagnosing R1234yf and R134a automotive air conditioning systems.

This compact, hard‑case kit brings professional‑style controls and durable fittings to both DIYers and technicians. It includes a four‑valve manifold with clear pressure dials, four color‑coded 5‑ft hoses, adjustable quick couplers for R1234yf and R134a, a self‑sealing can tap, adapters, and hand tools — everything needed to measure system pressures, add refrigerant, or connect to vacuum and recovery equipment. Built from brass connectors and thick rubber hoses, the set is made for repeated field use and portable storage.

How does the four‑way design simplify charging and evacuation?

The four separate valves let you control high and low sides independently while keeping a dedicated vacuum/refrigerant port. That separation reduces cross‑contamination and lets you run evacuation, pressure testing or targeted charging without swapping hoses.

• Individual red/blue valves for high and low service lines
• Yellow refrigerant hose dedicated to charging or recovery
• Black hose reserved for vacuum pump or recovery machine hookup
• Clear manifold window for visible fluid and charge status

Will this kit work with my car’s R1234yf or R134a system?

Yes — the BACOENG manifold set is built for R1234yf and R134a service. It includes adjustable quick couplers for both refrigerants and threaded adapters for common service ports, so you can connect to most modern automotive AC fittings.

• Includes R1234yf adjustable quick couplers and R134a adjustable quick couplers
• Left‑hand and right‑hand thread 1/4" to 1/2" adapters included
• Self‑sealing can tap for safe service bottle connection
• Works with household and automotive AC applications where compatible refrigerants are used

How durable and leak‑resistant are the hoses and fittings?

The hoses use high‑quality rubber and the fittings are machined brass to reduce wear and leakage risk during repeated service cycles. Replacement parts and a valve core wrench are supplied so you can maintain the kit on the job.

• Brass connectors for corrosion resistance and reliable seals
• Thick rubber hoses and gaskets to prevent refrigerant seepage
• Spare parts and tools for field maintenance and quick repairs
• Compact storage case to protect gauges and valves during transport

How easy is the set to read and carry between jobs?

The gauges have large faces and a clear glass window for quick pressure reads, and color‑coded hoses speed correct connections. The whole kit fits into a sturdy case that keeps parts organized and portable for mobile technicians or weekend mechanics.

• Large, easy‑to-read pressure dials with visible scales
• Color coding (red/blue/yellow/black) prevents hookup mistakes
• Compact, molded case for safe transport and storage
• All necessary fittings included to start charging immediately

Who is this for: The BACOENG AC R1234YF Gauge Set is aimed at automotive technicians, HVAC service providers, and experienced DIYers who service car or small residential AC systems that use R1234yf or R134a. It’s suitable for routine diagnostics, refrigerant topping, evacuation, recovery hookup, and pressure testing when reliable, portable tools are required. If you need a full‑function manifold kit with durable brass fittings, multi‑refrigerant compatibility and on‑site repairability, this kit provides the core components for professional‑level service without requiring separate couplers or adapters.
