Leak-Proof Air Conditioning A/C Quick Caps for R134A Systems, 2013-2020 Dodge Grand Caravan

Stop Losing Refrigerant. Seal It In. Traditional plastic A/C service port caps are dust covers — not seals. Even with new Schrader valves, you can lose up to 10% of your refrigerant every year. A failing valve can drain your system in minutes, leading to costly repairs, parts, and recharging. Why A/C QuickCaps? A/C QuickCaps are the first and only caps engineered to fully seal refrigerant in. Designed for R134A systems — the newer, more environmentally friendly refrigerant that is also more expensive to replace — these caps deliver a true secondary seal where standard caps fail. Leak-proof: Tested to hold full refrigerant pressure, even with failed or missing Schrader valves Patented quick-connect locking system: Installs in seconds — no tools required High-pressure HNBR O-ring: Seals refrigerant at the valve opening, blocking even microscopic leaks Universal fit: One set covers R134A service ports — no more hunting for the right cap Keeps contaminants out: Prevents dirt, moisture, and fluids from entering the port, stopping rust and corrosion Durable & reusable: Vibration-resistant design built for long-term use Technician-approved: Trusted by professionals for reliability and repeat-repair prevention These caps protect your system and your wallet. Sold as a pair with one Red high and one Blue low cap or both black. Dodge Grand Caravan 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020
