Wisscool HVAC Manifold Gauge Set 4-Valve for R410A/R134a/R22 — Dual 2.6" Gauges, 5ft Heavy-Duty Hoses

WISSCOOL's 4-valve HVAC manifold gauge set is a complete charging, evacuation and pressure-testing kit built for R410A, R134a and R22 systems.

This professional-grade manifold combines an upgraded dual-gauge assembly with four service hoses and a full complement of adapters to handle residential and automotive air conditioning work. The kit pairs shock-resistant 2.6" gauges with 5-foot, four-layer PVC hoses rated for high working and burst pressures, plus calibrated fittings and repair seals so you can charge, recover or test systems without running back to the shop.

How does this set make refrigerant charging and recovery easier?

The 4-valve layout gives separate control over both high and low sides plus an independent center charging/evacuation line for safe, accurate service. The clear, dry dials and built-in calibration screws help you read and fine-tune pressures quickly during charging or recovery jobs.

• Four-valve manifold lets you isolate and control refrigerant flow precisely.
• 2.6" gauges display readings in °F with 1.6% accuracy and calibration access.
• Yellow center hose dedicated to charging or vacuum work for safety and convenience.
• Hoses and fittings included so the kit is ready to use out of the case.

What durability features protect the gauges and hoses on the jobsite?

Gauges use a hybrid anti-shock core and a dry dial assembly to resist mechanical wear and keep readings visible in different weather. Hoses are constructed from four-layer PVC and rated to withstand high pressures, reducing rupture risk during heavy-duty service.

• Hybrid anti-shock gauge cores reduce damage from drops and vibration.
• Dry dials avoid internal fogging, improving legibility in humid conditions.
• Four-layer PVC hoses rated for 800 PSI working and 4000 PSI burst pressures.
• Robust fittings and spare seals included for long-term reliability.

Which refrigerants and systems are compatible with this manifold set?

This manifold works with common refrigerants R410A, R134a and R22, making it suitable for many HVAC and automotive AC systems. Multiple adapter fittings let you connect to a variety of service ports and tank valves without swapping tools.

• Direct compatibility with R410A, R134a and R22 refrigerants.
• Includes adjustable R134a couplers and both 1/4" and 5/16" charging valves.
• Tank adapters and angled/straight fittings support different service scenarios.
• Valve core key, pipe thimble and replacement seals for maintenance on-site.

What comes in the kit and what useful extras are included?

Beyond the manifold and hoses, the set supplies a wide range of adapters and service tools so technicians can begin work immediately. Spare seals and a valve core key are included to handle common leak sources and minimize downtime.

• Red high-side, blue low-side, yellow charge and black vacuum 5 ft hoses.
• Gauge pair (low 0–550 PSI, high 0–750 PSI) with calibration screws.
• Assortment: adjustable couplers, 1/4" & 5/16" valves, tank and angled adapters.
• Can tap, valve core key, pipe thimble and replacement seals for service continuity.

Who this product is for: HVAC contractors, refrigeration technicians and experienced DIYers who service air conditioning systems and need a portable, fully equipped manifold kit. It’s intended for trained users who understand refrigerant handling and safety; the kit provides the accuracy, durability and connector variety professionals expect for everyday charging, evacuation and pressure-testing tasks.
