Why Choose a 4-Way Manifold?

4-way manifolds provide four service ports instead of the standard three, offering greater flexibility for complex service operations. The additional port allows simultaneous connection to multiple devices (vacuum pump, recovery machine, refrigerant cylinder, and system) without disconnecting and reconnecting hoses. This saves time and prevents refrigerant loss during service operations.

3/8" Bore Advantage:

The 3/8" bore provides higher flow capacity compared to standard 1/4" manifolds, resulting in faster evacuation, charging, and recovery operations. This is particularly beneficial for larger commercial systems or when time efficiency is critical. The larger bore reduces pressure drop and allows refrigerant to flow more freely.

80mm Gauge Benefits:

• Large Dials – Easy to read from a distance
• Clear Markings – Precise pressure readings
• Professional Appearance – Premium quality gauges
• Multiple Scales – Refrigerant-specific pressure/temperature scales

Ball Valve Hoses:

Three of the four hoses feature integrated ball valves for manual shut-off control. This allows you to close individual hoses before disconnecting, preventing refrigerant venting and ensuring EPA compliance. The ball valves provide quarter-turn operation for quick on/off control.

Complete Kit Includes:

• 4-way manifold body with 80mm gauges
• 3 x 150cm (60") charging hoses (1/4" SAE) with ball valves
• 1 x 150cm (60") hose (3/8")
• Carrying case

Benefits:

• 4-Way Design – Four ports for maximum flexibility
• 3/8" Bore – Faster evacuation, charging, and recovery
• 80mm Gauges – Large, easy-to-read dials
• Ball Valve Hoses – EPA-compliant refrigerant containment
• 150cm Hoses – Extended reach for difficult installations
• Multi-Refrigerant – Works with R134a, R404A, R407C, R22, R507A
• Complete Kit – Includes carrying case
• Professional Quality – Built for daily commercial use

How to Use:

1. Connect blue hose to low-side (suction) service port
2. Connect red hose to high-side (discharge) service port
3. Connect yellow hose to refrigerant cylinder or vacuum pump
4. Connect fourth hose as needed (recovery machine, additional cylinder, etc.)
5. Open manifold valves as needed for service operation
6. Monitor pressures on 80mm gauges
7. Close ball valves before disconnecting hoses
8. Store manifold in carrying case when complete

150cm (60") Hose Length:

• Extended Reach – Access difficult installations without moving equipment
• Commercial Applications – Ideal for large equipment and rooftop units
• Reduced Movement – Less need to reposition manifold during service
• Professional Standard – Preferred length for commercial HVAC/R work

Maintenance:

• Inspect hoses regularly for cracks or damage
• Check gauge accuracy annually
• Test ball valves for proper operation
• Replace O-rings if leaks develop
• Keep valves clean and free from debris
• Store in carrying case when not in use
• Avoid over-tightening connections

Professional Quality: Mastercool 4-way manifold gauge sets are built to professional standards for accurate, reliable performance in demanding HVAC/R service environments. Essential tool for commercial refrigeration and air conditioning service work.
