Leak-Proof Air Conditioning A/C Quick Caps for R134A and R1234YF Systems, 2014-2026 Chevy Silverado, GMC Seirra, Gas Trucks

Note: From 2019-2024 Ram trucks used both R134A and R1234YF refrigerant. Please verify what refrigerant is in your truck before ordering. 

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 and R1234YF 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 all R1234YF 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.
