Super Tech R-134A A/C Recharge Kit vs Pinnaco R134a Refrigerant Recharge Hose Gauge Kit

The Super Tech kit is the safer pick for most DIYers because it bundles refrigerant with the gauge hose, so you get a complete recharge in one box. The Pinnaco is a hose and gauge only, with no refrigerant, so it only makes sense if you already have cans. Owners of the Super Tech kit call it easy to hook up and effective at getting the A/C cold, though a few report short-filled cans or a can that stopped spraying. The Pinnaco is a simpler metal-and-rubber tool with a 350 PSI low-side gauge and a built-in safety valve, but it carries no track record of owner feedback here.

• Choose the Super Tech kit if you want refrigerant and a gauge hose together for a one-time top-off on a car that uses R-134a.
• Choose the Pinnaco gauge hose if you already have R-134a cans and just need a durable charging hose with a low-side gauge and safety valve.
