I got the wrong gauges (r22, 134a, and 404a) and I need the 410a.** A: I see no reason why it shouldn't fit...threads should be the same...but you will need to be able to hook it up to your AC system and those end connectors may be your problem...make sure you have the proper end fittings that you need for your system. I have multiple gauges for mine that I can interchange. **Q: Hi i need a low side and high side for: R134A,507 and 404?** A: You need a gauge, gauge and hoses? **Q: Will this work for R134?** A: I'm a 20yr tech. It will work for any refrigerant really... it just doesn't give the saturation temp of R134a. But it will give pressures which is the main purpose of gauges. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good purchase *by P***R on 12 July 2025* ### ⭐⭐⭐⭐⭐ Perfect *by G***T on 18 March 2020* ### ⭐⭐⭐⭐⭐ Didn't have to search around town. *by D***A on 31 January 2026* ## Frequently Bought Together - Yellow Jacket 49138 3-1/8" Blue Compound, 30", 0-350 psi, R-22/404A/410A Gauge Degrees F - Yellow Jacket 49137 3-1/8" Red Pressure, 0-800 psi, R-22/404A/410A Gauge Degrees F - Yellow Jacket 19110 Ritchie Quick Coupler --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/678812126-ritchie-yellow-jacket-yellow-jacket-49138-3-1-8-blue](https://www.desertcart.tn/products/678812126-ritchie-yellow-jacket-yellow-jacket-49138-3-1-8-blue) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-08*
