TWTADE Car A/C Repair Kit — 2‑set: 270 O‑Rings, 100 Valve Cores & 2 Tools for R12/R134a

TWTADE's 2-set car A/C repair kit bundles 270 rubber O-rings and 102 valve cores plus two remover tools to service and reseal automotive air-conditioning systems.

This comprehensive kit supplies the common sealing and valve components technicians and DIYers need when repairing or refreshing a vehicle air conditioner. The kit includes eighteen sizes of green rubber O-rings for gaskets and hose joints plus a large assortment of oil-resistant valve cores, all stored in labeled plastic organizers for quick identification. It’s designed to replace worn seals and faulty valve cores used with R12 and R134a systems, helping restore tight seals and maintain performance after repairs.

Which parts are included and how are they organized?

The kit contains 270 rubber O-rings across 18 sizes and 100 valve cores, plus two valve-core removal tools. Components are sorted in plastic compartment boxes with labels to simplify selection during service.

• 270 green rubber O-rings in a range of internal diameters for fittings and hose ends
• 100 oil-resistant valve cores compatible with common A/C valve stems
• 2 metal valve-core removal tools for quick install and extraction
• Labeled plastic storage boxes for neat transport and fast part identification

How will these O-rings and valve cores perform on my vehicle?

O-rings are molded from flexible rubber to provide elasticity and sealing stability, while valve cores are manufactured for resistance to oil, corrosion and typical refrigerant conditions. They are intended for maintenance and routine replacements rather than OEM-critical repairs.

• Rubber O-rings: good elongation and long-term sealing properties
• Valve cores: corrosion and oil-resistant metallurgy for refrigerant environments
• Suitable for R12 and R134a service ports and many standard fittings
• Not a substitute for damaged service ports or major system component failures

How do I use the removal tools and replace a valve core safely?

Always depressurize and recover refrigerant using proper equipment before touching service ports. Use the supplied removal tool to unscrew the old valve core, replace it with a new one, and test for leaks before recharging the system.

• Recover refrigerant per local regulations before opening the system
• Insert the remover tool into the valve stem and turn counterclockwise to remove the core
• Install a new core by hand until snug, then tighten slightly with the tool
• Replace O-rings on fittings as needed and pressure-test for leaks

What vehicle parts and situations is this kit best suited for?

This set is aimed at repairing service valves, hose connections, fittings and small joints found in automotive A/C systems, pumps, and related refrigeration lines. It’s ideal for routine maintenance tasks, leak sealing after component swaps, and keeping a parts supply in a shop kit.

• Service valve core replacements during A/C port maintenance
• O-ring replacements on hose ends, fittings, and quick-connects
• General shop or mobile technician use for multiple vehicle makes
• Handy for hobbyists performing non-specialized A/C repairs

Who is this for: The TWTADE 2-set A/C repair kit targets automotive technicians, mobile mechanics, and experienced DIYers who service vehicle air-conditioning systems. It’s most useful when performing valve-core swaps, replacing common sealing O-rings, or stocking a maintenance kit for multiple cars. This product supplies many common sizes and fast-access storage but should be used with proper refrigerant-handling tools and safety procedures; for major system faults or compressor and condenser replacement, consult a professional technician.
