Wayona HVAC Valve Core Removal & Service Wrench Kit — 22PC Brass/Stainless Set, Dual SAE 1/4" & 5/16" Ports

The Wayona 22-piece HVAC valve core removal and service wrench kit is a complete refrigeration and mini-split maintenance set that lets you remove/replace valve cores and service fittings without venting refrigerant.

This compact toolkit bundles a brass valve core remover/installer, multi-size refrigeration wrenches, hex bit adapters, spare valve cores and adapters sized for common R-systems to handle routine maintenance on residential and light-commercial refrigeration and mini split air conditioners. Built from brass and stainless steel components, the set is designed for corrosion resistance and reliable fit with SAE 1/4" and 5/16" ports so you can work efficiently in confined spaces.

How does this kit save time during routine HVAC service?

The valve core tool lets you extract or install valve cores while leaving the system pressurized, so you don’t need to recover refrigerant for simple core swaps. The multi-function wrenches and flip levers accelerate adjustments in tight areas, reducing disassembly and downtime.

• Valve core remover/installer for in-system core swaps
• Dual-size SAE 1/4" & 5/16" port compatibility
• Ratchet-style refrigeration wrench with quick-flip steering levers
• Includes 10 replacement valve cores and spare gaskets

Which refrigerant systems and equipment is this compatible with?

This Wayona kit supports a wide range of residential and light commercial refrigerants used in HVAC and refrigeration service, including many R-series systems. It’s tailored for mini-splits, home refrigerators and air conditioning service but is not intended for automotive AC applications.

• Mini-split and household refrigeration-ready adapters included
• Not recommended for automotive air conditioning service
• Brass and stainless materials resist corrosion on refrigerant fittings

What tools and parts are included to handle different valve sizes?

The set contains a variety of wrench sizes and adapters so one kit covers multiple valve configurations. Hardened hex bit adapters and brass fittings give a durable interface between the wrench and system connections for repeated field use.

• 1 valve core remover/installer tool and 10 spare valve cores
• 4-in-1 refrigeration wrench sizes: 1/4", 3/8", 3/16", 5/16"
