- R134a Replacement - Hydrocarbon blend that is 100% natural, safe for the ozone and non global warming. Chemically compatible with R134a systems.
- 6oz (11.7 fl oz) Cans - Compressed gas is measured by weight. This gas is light weight compared to others, but has the same "volume". Guaranteed that you will use no more than normal
- SSV Cans - Self Sealing Valve allows for the storage of unused gas. Requires SSV compatible tool. Avoid "piercing" style tools or the gas may come out slowly or not at all.
- Disclosures - Product is flammable like many other modern refrigerants. Observe all precautions on the product lablel when handling and storing. Follow all legal requirements when charging your system. Hydrocarbon blend refrigerant for NON MVAC use in 6oz SSV Cans.
- ENGINEERED R134a REPLACEMENT - HIGH-EFFICIENCY FORMULATION - Hydrocarbon-based A/C refrigerant engineered to replace R134a cooling performance when used correctly. Designed for A/C systems originally charged with R134a and serviced by informed DIY users
- PREMIUM HIGH-PURITY SPECIFICATION (99.5%+) - Manufactured to a tightly controlled formula with purity exceeding common refrigerant standards (AHRI 700). No mystery fillers, moisture contamination, or inconsistent blends found in low-grade alternatives
- SIGNIFICANTLY LOWER CHARGE WEIGHT REQUIRED- Hydrocarbon refrigerants absorb more heat per ounce than traditional R134a. As a result, substantially less refrigerant is required to achieve comparable cooling performance. Do not charge by R134a weight
- DESIGNED FOR CONSISTENT, EFFICIENT COOLING PERFORMANCE- Higher heat absorption per unit mass can deliver equal or colder vent temperatures than R134a in many systems when properly charged. Reduced compressor load and efficient evaporator heat transfer contribute to fast pull-down and stable cooling
- PROFESSIONAL-STYLE SELF-SEALING VALVE- 6 oz net cans feature a self-sealing female valve with standard ½″ ACME threads, compatible with common R134a charging hoses. No puncture cans, no special adapters required
- GREEN REFRIGERATION SOLUTION: ZeroR AC Refrigerant is a 100% natural hydrocarbon gas, offering a more eco-friendly alternative to traditional AC recharge like R134a. It helps reduce environmental impact while providing reliable cooling performance
- R134A READY INSTALLATION: Designed to fit R134a systems, ZeroR AC Refrigerant installs just like any standard refrigerant. The cans feature R134a-compatible threads, ensuring easy and seamless installation with your existing R 134a refrigerant can taps
- SMALLER CAN BIGGER IMPACT: Each can of our car AC refrigerant holds 6oz of refrigerant, but its performance is equivalent to 16oz of R134a. This makes it a highly efficient and cost-effective option, requiring less product while maintaining excellent performance
- BUILT FOR SAFE USAGE: ZeroR AC Car Refrigerant is rated with a class 2.1 rating, similar to newer refrigerants. When used in systems designed for refrigerants, it’s safe and poses no danger to users under normal operating conditions
- REGULATED FOR LEGAL SAFETY: ZeroR AC Recharge Can is approved for use in R134a systems only, in compliance with EPA regulations. It ensures proper functionality without the risk of mixing refrigerant types, providing peace of mind and legal safety

Important: A tick noise is characteristic of Direct Injected Engines. Please refer to the latest version of 07-06-04-025 for additional information.
A customer or technician may comment of engine or High Pressure Fuel Pump tick noise that is very loud in the cab of the truck.
Comparison with another truck having the same powertrain could show the other truck is quieter.
Recommendations / Instructions
During vehicle build a possibly exists that an acoustic seal was knocked out of place during assembly.
With this acoustic seal dislodged or missing the High Pressure Fuel pump tick / click noise can be heard easily inside the cab of the truck.
