The Right Gauge For The Right Job
With digital and analogue options available, plus heat pump kits and charging accessories, everything you need for pressure testing, evacuation and charging is covered in one place.
Manifolds
Manifold gauges are at the heart of most AC service work. Whether you prefer a straightforward two-valve analogue setup or a fully connected digital system, the range at BES gives you both. For traditional setups, options like the Javac Two Way Standard Manifold with Sight Glass or Refco Two Way R410A Manifold provide dependable, easy-to-read performance. If you’re working with R410A or R32 systems, dedicated multi-gas and refrigerant-specific options are available. If you prefer digital precision, the Testo 550S and 550i Digital Refrigeration Manifold Sets offer Bluetooth connectivity, app integration and real-time measurement tracking. For heat pump work, the Testo 558s Heat Pump Kit is designed specifically with modern systems in mind.
2-Way vs 4-Way Manifolds
Two-way manifolds handle standard high- and low-pressure readings for most servicing jobs. Four-way manifolds add an additional port, giving more flexibility when evacuating, charging or recovering refrigerant. Larger systems or more complex servicing tasks often benefit from a four-valve setup.
Pressure Gauges
Whether working up to 10 bar or 30 bar, we stock gauge adjustable Bourdon tube gauges that offer great performance for years to come. The Refco M2-500-DS-R22 and Javac EL54516 gauges cover different pressure ranges, making them suitable for a variety of refrigerant systems.
Vacuum Gauges
Ideal for quickly testing any differences in atmospheric pressure, a reliable vacuum gauge can help you out in a pinch. The likes of the Javac VG64 Digital Vacuum Gauge, with its magnetic HVAC strap, gives accurate readings and a 0.5 second update rate.
Vacuum Probes
Ideal for fast testing vacuums through a single port, you always want a vacuum probe that prides itself on ease of use. A product like the Testo 552i Wireless Vacuum Probe does just that, with a 45° angle probe and Bluetooth connectivity for app integration.
Heat Pump Kits
Heat pump work calls for a slightly different setup, and dedicated kits help keep everything straightforward on site. Options such as the Testo 558s Heat Pump Kit are designed with modern heat pump systems in mind, bringing together a digital manifold and the key accessories needed for commissioning and servicing.
Digital vs Analogue - Which Gauge Should You Choose?
Analogue gauges are dependable, familiar and well suited to everyday servicing work. Digital manifolds offer added features such as temperature calculation, Bluetooth connectivity and refrigerant database integration and are useful for engineers who want faster diagnostics and cleaner reporting. The right choice often comes down to how often you work on AC systems and the level of detail required.

FAQs
What is the difference between a 2-way and a 4-way manifold?
A 2-way manifold measures high and low pressure. A 4-way manifold adds an extra port, making evacuation, charging and refrigerant recovery more flexible.
Are these gauges compatible with R32 refrigerant?
Many manifolds stocked by BES are compatible with R410A and R32 systems. Always check individual product specifications before use.
Do I need a separate vacuum gauge?
While some digital manifolds include vacuum measurement, a dedicated digital vacuum gauge often provides more accurate evacuation readings.
How often should HVAC gauges be calibrated?
Regular calibration is recommended to maintain accuracy, especially for professional servicing work. Follow manufacturer guidance for servicing intervals.
What is the difference between Javac and Testo manifolds?
Javac manifolds offer robust analogue and digital options suited to everyday servicing. Testo digital manifolds provide advanced features such as Bluetooth connectivity, app integration and expanded refrigerant databases.
