R1234yf Universal Charging Hose with Gauge — 2021+ Automotive AC

A universal charging hose with integrated pressure gauge designed specifically for R1234yf automotive AC systems — the refrigerant standard in virtually all vehicles manufactured after 2021, and in many European and some domestic vehicles going back to 2013. R1234yf service fittings are intentionally incompatible with R134a fittings to prevent dangerous cross-contamination between the two refrigerants.

Specifications

• Compatible refrigerant: R1234yf (HFO-1234yf)
• Connection: R1234yf-specific low-side fitting (not compatible with R134a ports)
• Gauge: Included
• Application: 2021+ domestic vehicles; many 2013–2020 European and some domestic vehicles

How to Confirm Your Vehicle Uses R1234yf

Check the underhood AC service label — it will clearly state R-1234yf if the system uses it. R1234yf service ports are a different size and shape than R134a ports, and this hose will only connect to R1234yf-compatible ports. If the hose doesn't fit, your vehicle likely uses R134a — see our R134a charging hose with gauge.

Important: R1234yf Refrigerant Sold Separately

Frequently Asked Questions

Can I use this hose with R134a cans?
No. R1234yf fittings are intentionally designed to be incompatible with R134a connections. This is a safety feature — mixing R134a and R1234yf in a system causes serious damage.

Do I need special equipment beyond this hose?
For simple top-offs using small R1234yf cans, this hose is sufficient. For full system evacuations and recharges, SAE J2843-certified R1234yf recovery/recycling/recharge equipment is required.
