Worked perfect. I looked up self sealing can and they use a 1/2 connecting instead of 1/4. This is 1/4 connect to piercing tool. I'm not sure if this piercing part will work with self sealing can by adding an adapter as it is not real long. They do make a piercing fitting for the self sealing can that will fit to the yellow hose. Then gauges will work OK. Guess need to send orion motor tech a email to say need an another adapter to order to use on self sealing cans. This is made to use in normal automotive air and home ac fittings. Fitting I s fairly cheap. **Q: Are the gauges in metric or standard** A: standard **Q: What are the extra parts in a separate bag ?** A: The extra parts in the separate bag are three white washers and one connector. **Q: Where is it made?** A: China ## Frequently Bought Together - Orion Motor Tech AC Gauges, AC Manifold Gauge Set for R134a R12 R22 R502, 3 Way Automotive AC Gauge Set with Antishock Gauges Hoses Couplers Adapter, Puncturing Can Tap Freon Recharge Kit - Orion Motor Tech Vacuum Pump, 3.5 cfm 1/4 hp HVAC Single Stage Vacuum Pump for R12 R22 R134a R410a R502, Auto AC Vacuum Pump Kit for Automotive Air Conditioner Resin Degassing & More, Oil Included - Refrigeration Technologies RT201B Nylog Gasket/Thread Sealant, 30 ml (1 Pack) --- ## 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.us/products/69002780-omt-3-way-ac-manifold-gauge-set-for-r12-r134a](https://www.desertcart.us/products/69002780-omt-3-way-ac-manifold-gauge-set-for-r12-r134a) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-30*
