OXDFK R134A 31‑Piece Valve Core Quick Remover & Installer Kit — Brass High/Low Pressure Connectors, Leak‑Reducing AC Service Set

OXDFK 31‑piece R134A valve core quick remover and installer kit is a complete brass tool set designed to remove, install and seal AC valve cores for automotive and HVAC R134A systems quickly and without refrigerant loss.

This kit collects the common components technicians and DIYers need to service R134A air conditioning systems: durable brass connectors, valve cores in two common types, service caps, and dedicated removal/installation tools for both high and low pressure ports. Built for repeat garage or field use, the set focuses on secure connections and efficient, leak-reducing operation so you can change valve cores without evacuating refrigerant or risking damage.

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

The kit’s quick‑connects include a high‑pressure (red) connector and a low‑pressure (blue) connector sized to fit standard R134A service ports and featuring a quarter‑turn ball valve. Opening and closing that valve isolates the port while the core is removed or installed, reducing refrigerant loss and simplifying the procedure.

• High connector: red, 16mm inner diameter for high‑pressure ports
• Low connector: blue, 13mm inner diameter for low‑pressure ports
• Ball valve with quarter‑turn control to stop flow when needed
• Two quick removal tools: one for high and one for low pressure

What components come in the 31‑piece set and why are they useful?

The kit supplies ten R134A valve cores, ten 5V1 cores, eight AC service port caps, a double‑ended valve stem remover, and two quick removal tools — giving you replacements and tools for most common repair scenarios. These parts let you swap cores, cap unused ports, and handle different stem styles without searching for extras.

• 10 × R134A valve cores for standard replacements
• 10 × 5V1 valve cores for alternative stem types
• 8 × service port caps to protect ports after service
• 1 × double‑ended valve stem removal tool for tight spaces

Is the kit durable and easy to operate for repeated use?

Materials were selected for longevity: brass body components provide strength and impact resistance, stainless steel stems resist wear, and aluminum knobs offer easy handling with anti‑skid texture. The grab mechanism holds the core firmly for a controlled pull, letting you remove or install cores quickly and reliably.

• High‑quality brass construction for rugged service work
• Stainless steel stem for corrosion resistance and durability
• Aluminum knobs with textured grip for secure turning
• Design focused on user control to avoid over‑torquing or damage

How do I use the valve core removal and installation tools step‑by‑step?

The process is straightforward: close the tool valve, connect to the AC quick connector, open the valve and engage the removal tool, then extract the core and reseal the port. The kit’s double‑ended tool and clear connector sizing make it easy to work in confined spaces.

• Step 1: Pull out valve rod and close valve, attach connector to service port
• Step 2: Open the tool valve and push the stem in, rotate knob clockwise
• Step 3: After loosening core, pull lever and close valve to isolate system
• Step 4: Unscrew the extremity port and remove the valve core

Who this set is for: technicians, mobile HVAC service providers, and informed vehicle owners who perform routine AC maintenance or valve core changes on R134A systems. If you need a compact, ready‑to‑use kit with spare cores and caps — and tools sized for both high and low pressure service ports — this OXDFK kit gives professional‑grade hardware in a single package. It’s best suited for users familiar with basic AC service practices who want to reduce downtime and refrigerant loss during valve work.
