jiouxip Valve Core Remover & HVAC Service Wrench Kit — Dual 1/4"/5/16" Ports, 10 Valve Cores, Brass/Steel

jiouxip Valve Core Remover Installer Tool and HVAC Service Wrench Set is a compact brass-and-steel kit that removes and installs valve cores on refrigeration and air-conditioning ports without discharging refrigerant.

This professional kit combines a dual-size service wrench, brass valve core remover, hex bit adapters and ten replacement valve cores to streamline routine HVAC and refrigeration maintenance. Built for compatibility with common refrigerants and port sizes, the set makes on-site repairs faster by allowing technicians to remove or replace leaking valve cores while the system remains pressurized.

How does the kit let me change a valve core without losing refrigerant?

The brass core remover fits inside the valve stem and engages the core so you can extract or thread a new core while the system stays sealed. The secure fit minimizes leakage and the steel ball retainer prevents adapters from slipping during use.

• Inner-core insertion design for controlled removal
• Brass construction reduces deformation under pressure
• Steel ball retainer keeps adapter engaged in wrench

Which port sizes and refrigerant systems is this compatible with?

Designed with dual SAE ports — 1/4" and 5/16" — plus a 3/8" to 1/4" adapter, the kit fits the most common refrigeration and HVAC fittings. It supports systems using R410A, R22, R12, R407, R404 and R32 among others, making it useful across residential, commercial and refrigeration equipment.

• Dual-size service wrench: 1/4" and 5/16" ports
• Included 3/8" to 1/4" refrigeration adapter
• Compatible with a broad range of refrigerants and valves

What materials and features ensure durable, reliable performance?

The remover and adapters are made from brass for impact resistance and corrosion tolerance, while the wrench and retaining elements use hardened steel for secure operation. The steel ball on the adapter top locks components in place so routines are faster and parts don’t fall out during service.

• Brass valve core remover resists wear and deformation
• Hardened steel ball retainer prevents adapter loss
• Compact, easy-to-handle 2" adapter length for access in tight locations

What tools and spare parts are included in the package?

The kit arrives ready for immediate use with a service wrench, valve core remover, adapters and spare cores so you can perform a repair in one trip. Everything fits in a small technician’s toolbox for mobile service jobs.

• 1 pc valve core remover installer tool (brass)
• 1 pc dual-port HVAC service wrench (1/4" & 5/16")
• 1 pc 3/8" to 1/4" refrigeration service wrench
• 2 hex bit adapters and 10 valve cores included

Who this kit is for: HVAC technicians, refrigeration service professionals, gas furnace repairers and DIYers who perform routine valve core maintenance will benefit most from this jiouxip set. It’s particularly useful when you need a compact, reliable toolset that accommodates common SAE port sizes and a variety of refrigerants without requiring system shutdown or refrigerant recovery for valve-core swaps.
