OXDFK R134A Valve Core Quick Remover & Installer Kit — 31-Piece Brass Set, High/Low Pressure Connectors

OXDFK's 31-piece R134A valve core quick remover and installer kit is a complete brass-bodied set for removing, installing, and sealing AC valve cores on high- and low-pressure refrigerant ports.

This kit assembles everything technicians and DIYers need to service R134A automotive and HVAC service ports: dedicated high- and low-pressure quick connector tools, spare valve cores, replacement caps, and a double-ended stem tool. Built from brass, stainless steel, and aluminum, the components are sized for common R134A fittings and designed to minimize refrigerant escape while you change valve cores quickly and safely.

How does the kit prevent refrigerant leakage during valve core changes?

The kit uses quarter-turn ball valves in the quick-connects so you can isolate pressure before and after removal. The high-pressure (red) connector and low-pressure (blue) connector match typical diameters for fast, secure attachment.

• High connector: 16 mm inner diameter, red color for easy ID
• Low connector: 13 mm inner diameter, blue color for quick recognition
• Ball valve operation for instant shutoff to reduce refrigerant loss
• Threaded caps and tight fittings to reseal service ports after work

What materials and design features make this kit durable?

Core pieces use high-quality brass and stainless-steel stems for strength and corrosion resistance, while aluminum knobs give a firm, lightweight grip. Textured knobs lower slip risk so you can apply controlled torque without damaging valve stems.

• Brass bodies for impact resistance and long life
• Stainless-steel valve stems for rust protection
• Aluminum knobs with anti-slip texture for secure handling
• Robust quick-connect joints that stand up to repeated use

How easy is it to remove and install valve cores with this set?

Operation follows simple, repeatable steps: connect the quick tool, open the internal valve, engage the core grabber, rotate to release, then withdraw and reseal the port. The core grabber holds the core firmly for one-handed extraction, speeding up routine maintenance.

• Stepwise use: connect, open valve, push and rotate knob, remove core
• Double-ended stem remover for awkward or recessed valve stems
• Core grabber provides positive suction for easy removal
• Includes spare R134a and 5V1 cores to complete most jobs

What parts are included and how do they cover common service needs?

The kit brings together replacement cores, service port caps, two quick-removal tools, and a stem tool to handle most R134A valve core service tasks on vehicles and HVAC units. Having multiple cores and caps on hand prevents downtime on the job.

• 10 R134A valve cores and 10 5V1 valve cores for replacements
• 8 AC service port caps to reseal ports after service
• 2 quick-removal tools (high and low pressure) for both sides of the system
• 1 double-ended valve stem removal tool for tougher cores

Who is this for? The OXDFK 31-piece kit is made for automotive mechanics, HVAC technicians, and capable DIYers who service R134A refrigerant systems and need a convenient, durable set for valve core replacement. It’s especially useful when minimizing refrigerant loss matters and when having spare cores and caps on hand reduces repeat trips. If you perform routine AC maintenance or field service calls, this kit supplies the essential fittings and tools to work faster and with greater reliability.
