Mastercool HVAC/R Brass Manifold Gauge Set 59161 — R22/R404A/R410A, 3×60" Hoses & Silicone-Dampened Gauges

The Mastercool 59161 is a professional two-way forged brass manifold gauge set built for accurate pressure readings and durable field performance with R22, R404A and R410A systems.

Engineered and assembled in the U.S., the 59161 combines heavy-duty brass construction, silicone-dampened gauges and premium 60" hoses to deliver reliable service for HVAC/R technicians. It balances rugged build quality with features that reduce wear and improve readout stability, making it suitable for routine maintenance, diagnostics and system servicing across residential and commercial refrigeration and air conditioning equipment.

How accurate and stable are the pressure readings?

The 59161 uses large 3 1/8" silicone-dampened gauges that minimize needle vibration for clearer readings under fluctuating conditions. Gauges are recalibrateable and color-coded to match R410A, R22 and R404A scales to speed identification on the job.

• 3 1/8" silicone-dampened, recalibrateable gauge faces for reduced needle bounce
• Color-coded scales for quick refrigerant recognition
• Large dial size improves visibility in dim or crowded service spaces

Will the manifold hold up to daily field use and rough handling?

Yes—the main body is forged from heavy-duty brass for corrosion resistance and long-term durability in harsh environments. All-metal angled handles and free-floating piston valves reduce internal wear and provide smoother operation over many service cycles.

• Forged brass body resists corrosion and deformation
• Free-floating piston valves lower internal friction and extend O-ring life
• Angled, all-metal handles for durable, ergonomic control

Are the hoses and fittings suitable for high-pressure refrigerants?

The set includes three 60" high-pressure, kink-resistant hoses with 1/4" SAE standard fittings designed for frequent connection and disconnection. Premium-grade hose construction preserves flexibility under pressure while resisting kinks and abrasion on the jobsite.

• Three 60" premium high-pressure hoses for extended reach
• 1/4" SAE standard fittings for broad compatibility
• Kink-resistant rubber formulation for durability during repeated use

What accessories or conveniences are included for transport and organization?

The kit ships in a compact, sturdy carrying case that protects components and keeps everything organized for transport between jobs. A built-in hose storage hook lets you hang hoses off the manifold for hands-free operation and neat storage in the case.

• Compact protective carrying case for tool safety and portability
• Integrated hose storage hook for tidy, hands-free hose management
• Color-coded connections match gauge scales for quick setup

Who is this for: The Mastercool 59161 is aimed at HVAC/R service technicians, installers and refrigeration professionals who need a robust, versatile manifold set for R22, R404A and R410A systems. It suits those who prioritize durable materials, readable gauges and dependable hose performance for daily diagnostic and maintenance work across residential, commercial and light industrial sites.
