Is your car's AC system missing those little plastic caps on the service ports? Don't ignore it – those caps keep dirt, moisture, and debris out, which can mess with your AC performance. This NIIIYTYB 20-piece set has you covered (literally!) for most vehicles with R134a systems.
You get a bunch of sizes: 13mm, 13.5mm, 14mm, 16mm, 17mm, and 17.5mm. That includes blue caps for the low-side port and red caps for the high-side port (plus black rubber seals for a tight fit). It's a complete assortment so you can find the right fit for your car, truck, or SUV.
Made from tough plastic, they're built to handle weather and engine heat. They're direct replacements for OEM caps, so they fit snug and look right. *Quick note: they don't fit 2014 Toyota RAV4 or 2018 Nissan Versa – always double-check your ports before buying!
Installing them is as simple as popping the old ones off and clicking these on. No tools needed. Perfect for DIY maintenance, keeping your AC system clean between charges, or just replacing lost or cracked caps. Keep your cool this summer!
