Luumtee Car A/C Repair Kit 6‑Set 838‑Piece – R12/R134a Valve Cores & O‑Rings

Luumtee 6-set Car A/C Repair Kit is a complete 838-piece service kit that includes valve core tools, 102 valve cores, 530 O-rings, gaskets, dust caps, disconnect tools and organized storage for vehicle A/C maintenance.

This all-in-one Luumtee kit consolidates common A/C service parts and the specialized tools technicians and DIYers need to inspect, repair or reseal automotive air-conditioning systems. Components are sorted into compartmentalized storage so you can quickly locate the correct size parts for R12 and R134a applications, and the kit includes both high- and low-pressure valve core tools, compressor gaskets and fuel-line disconnects to cover most routine A/C tasks.

What exactly is included and how is it organized?

The kit bundles six complementary sets into one compact package: valve core tools, valve cores, a large selection of O-ring seals, dust caps, fuel-line disconnect tools and compressor gasket seals. Each part type is kept in its own labeled plastic box to prevent mix-ups and speed up workflow.

• 23-piece valve core remover/installer tool set (aluminum/brass alloy)
• 102 valve cores for R12 and R134a service
• 530 assorted O-rings in multiple sizes and materials
• 77 protective charging port dust caps in various colors
• 16 A/C fuel-line disconnect tools for quick fittings
• 90 compressor gasket seals and rubber/metal washers

How durable and compatible are the parts?

Luumtee uses corrosion-resistant brass and aluminum alloy for valve cores and tools, while O-rings and compressor seals are made from wear-resistant elastomers to preserve oil- and gas-tight interfaces. The assortment includes common sizes intended for passenger vehicles and light trucks, covering typical OEM dimensions for R12 and R134a fittings.

• Valve cores and tools: brass/aluminum alloy for corrosion resistance
• O-rings: multiple elastomer compounds and sizes for varied ports
• Gaskets: layered metal rings and rubber washers to improve sealing
• Dust caps: protect ports from dirt and moisture when disconnected

Which maintenance tasks will this kit help me complete?

This kit supports a wide range of A/C service jobs from routine component swaps to leak-sealing and line disconnections. It’s designed for tasks like replacing valve cores, refreshing worn O-rings during line repairs, changing compressor gaskets and decoupling quick-connect fuel or refrigerant lines.

• Replace or tighten A/C valve cores and service ports
• Swap O-rings during hose or fitting replacements to prevent leaks
• Install new compressor gaskets during component swaps
• Use disconnect tools to separate quick-connect lines safely

How does organization and storage make jobs faster?

Each component group is stored in its own compartmentalized box so you won’t waste time sorting parts on the bench. Clear labeling and separate containers let you grab the right size O-ring, valve core or gasket at a glance and keep leftovers protected for future use.

• Individual plastic boxes for each part type reduce cross-contamination
• Compartments sorted by size and model speed part selection
• Compact kit footprint keeps your workspace uncluttered
• Durable cases protect small parts from loss and damage

Who is this for: The Luumtee 838-piece A/C repair kit suits automotive technicians, mobile mechanics and competent DIY enthusiasts who perform regular A/C maintenance or small repairs on cars and light trucks. It’s best for users who want a broad inventory of replacement seals and service tools in one organized kit rather than buying individual components for every job.
