413-piece R134a valve core kit

This 413-piece kit supplies every component needed to service R-134a automotive air-conditioning systems. It includes valve core tools, O-ring installation tools, 270 sealing rings and 100 quarter-inch valve core gaskets. Professional technicians and DIY owners receive a single package that covers removal, replacement and sealing tasks without sourcing parts separately.

Tool design prevents refrigerant loss

The quick remover uses a 16 mm red high-pressure joint and a 13 mm blue low-pressure joint with an integrated ball valve and threaded disassembler. This arrangement lets the user seal the system while swapping the valve core so refrigerant stays contained. Copper valve bodies and HNBR hose seals resist wear, and the core claw penetrates the inner valve core for positive control during installation or removal.

R-134a refrigerant compatibility decides fit

The kit is built exclusively for R-134a systems and uses quarter-inch fittings throughout. Buyers working with other refrigerants or metric thread sizes cannot use these components. The 413-piece count covers high-volume shops, but occasional users who only need a single valve core tool will find most of the kit unnecessary.

Questions about this item

How do I confirm the valve core tool is sealing correctly after I install a new core?

After installation, the 16 mm red high-pressure joint and 13 mm blue low-pressure joint on the disassembly tool let you close the built-in ball valve, trapping refrigerant so you can verify pressure holds without loss.

Which individual pieces come in the 413-piece kit and what must I supply myself?

The kit includes 39 R134a spool quick-removal components, 270 sealing rings, 4 O-ring installation and removal tools, and 100 1/4-inch valve core gaskets; no additional components are included.

Should I choose this 413-piece set or a smaller version for occasional R134a work?

This single 413-piece set (part MAD-DaisyInner-0158) provides 39 quick-removal pieces, 270 sealing rings, 4 O-ring tools and 100 1/4-inch gaskets; no alternative capacities are offered.
