R134a KIT – Kit contains (2) 18oz cans of R134a refrigerant with stop leak and a reusable can tap with gauge. A total of 36oz of R134a is enough to recharge almost every vehicle, just 18oz is not enough if you have a completely empty system.
STOP LEAK – The stop leak in this kit is good for sealing leaks in rubber components such as o-rings. This is a basic stop leak and can not repair more severe leaks. Products like ZeroR Max Seal are much stronger and can even repair leaks in metal components.
CAN TAP & GAUGE – Reusable can tap and gauge for similar EZ Chill products. Note, this is NOT a universal can tap and can not work on common R134a threaded products. For a truely universal can tap check out the ZeroR brand of tools and refrigerants.
INSTRUCTIONS – Steps on product should be followed closely. With vehicle running and AC set to Max Cool, connect can to low side service port. Dispense refrigerant into system in short bursts, checking the gauge in between dispensing for proper charging levels.
LEGAL – Complies with Section 612 of the EPA Clean Air Act, EPA Compliant in Self Sealing Cans. R134a Refrigerant for MVAC use in 18oz self sealing valve cans.
