Mimorou HVAC Valve Core Remover & Wrench Kit, 18-Piece — Dual 1/4" & 5/16" Valve Tool, Ratchet Wrenches, Test Leads

Mimorou 18-piece valve core remover and wrench kit is a complete HVAC service set that removes and installs valve cores, offers multiple wrench sizes, and includes test leads and adapters for common residential and commercial refrigerant systems.

This compact, corrosion-resistant tool set brings together brass valve-core tools, stainless carbon-steel wrenches, hex adapters and electrical alligator clips so technicians can service refrigeration and air-conditioning service ports without losing refrigerant. It supports the most common refrigerants and port sizes used in building HVAC work, and organizes replacement valve cores and fittings in one kit for fast field repairs.

Which refrigerant systems and port sizes does this kit work with?

The Mimorou kit is designed to be compatible with a wide range of residential and light-commercial refrigerants and service valves. The dual-head valve core tool and included brass adapter fit standard 1/4" and 5/16" ports used on R22, R12, R407, R410A, R404 and R32 systems. It is not intended for automobile air-conditioning systems.

• Dual-size valve core tool: 1/4" and 5/16" port compatibility
• Includes brass adapter for R410A and R32 service connections
• Supplies 20 spare valve cores suitable for common HVAC valves
• Not recommended for vehicle A/C systems

How do the wrenches and adapters make repair work faster?

The set includes curved-handle ratchet wrenches in the most used sizes so you can access tight spots and apply torque without slipping. Two hexagon head adapters with a bead retention design keep sockets secure, while the chromed carbon-steel construction resists bending under typical service loads.

• Wrench sizes included: 1/4", 3/8", 3/16", 5/16" for versatile use
• Curved handles improve access in confined equipment cabinets
• Bead-structured hex adapters prevent accidental disengagement
• Chrome finish for corrosion resistance and easy cleaning

What electrical and testing accessories are included for safe troubleshooting?

The kit includes an HVAC adapter cord (approx. 61.5 cm) with UL-rated wiring and large alligator clips suitable for typical 0–30 amp testing on 120V circuits. Ten color alligator clips and test leads provide secure connections for continuity and power checks, helping technicians verify circuits before service.

• 24.21-inch (approx. 61.5 cm) HVAC adapter cord with UL-certified wire
• Large alligator clips rated for up to 30 amps and 14 AWG cable
• Ten color-coded alligator clips for clear test-point identification
• Instructions recommended: confirm voltage and testing procedure before use

How durable and reliable are the tools in the set?

Components are made from brass and chrome-plated carbon steel for strength and resistance to wear in ordinary HVAC environments. The valve core tool’s brass construction minimizes galling on service ports, and the chromed wrenches hold up to repeated torqueing during maintenance jobs.

• Valve core tools: brass for strength and corrosion resistance
• Wrenches: carbon steel chrome-plated to resist bending and rust
• Hex adapters: engineered bead structure to stay seated
• Replacement cores included to finish multiple service calls

This Mimorou kit is tailored for HVAC technicians, maintenance professionals and serious DIYers who perform refrigerant-system servicing at homes or commercial buildings. It’s appropriate for those who need a portable, ready-to-use combination of valve-core tools, wrenches and electrical test leads—especially when compatibility with R22, R410A and R32 systems is required. Before using electrical items, confirm local codes and voltage, and follow safe testing procedures to protect equipment and personnel.
