## Description

AC Gauges, AC Diagnostic Manifold Gauge Set for R410a R134a R22 Refrigerant, Brass Body 3-Way Car HVAC Gauge Set with 4FT Hoses Adjustable Couplers Adapter and Can Tap Freon Charge Kit

## Features

- COMPLETE GAUGE SET： The FavorCOOL multi-functional AC diagnostic manifold gauge kit is the complete package for all of your AC freon charging, evacuation, diagnostic check and recovery needs for both automobiles and homes. The kit includes a 3-way gauge, 3 color-coded 4ft hoses suitable for R410a recharging, 2 adjustable 1/4'' snap-in quick couplers, a brass tank adapter, and a can tap all stored in a portable plastic hard case. This professional 3 valve air conditioning diagnostic manifold gauge set is completely compatible with R134A R410a R22 R502 refrigerants.
- PRECISE & DURABLE MANIFOLD GAUGE： With its all solid brass connectors, heavy-duty brass body, and corrosion-resistant design, the 3-way 3-valve brass body manifold A/C gauge is both precise and durable. The large, easy-to-read dial is color-coded for quick reference to pre-set scales for various refrigerants such as R22, R134a, and R410a. Calibration screws allow for fine-tuning, and a transparent sight window allows for easy monitoring of charging and recovery. An added free-rotating hook makes it easy to hang anywhere, and the blue low-pressure gauge has a range of -30inHg550PSI, while the red high-pressure gauge has a range of -30inHg760PSI.
- HIGH PRESSURE HOSES FOR R410A： Our high-pressure hoses are 4 ft long apiece and honorably certified by CSA. These multi-layers hoses are made of 100% virgin Teflon diaphragms and other qualified materials with the highest industry standards. The hoses are anti-abrasion, anti-corrosion, and 100% capable of resisting high pressure for charging refrigerants such as R410a with a working pressure of 800psi and a burst pressure of 4000psi, making them much safer and more durable than most other products on the market.
- ADAPTERS & CONNECTORS： The ready-to-go kit comes with snap quick couplers fit for car R-134a service ports, with 1/4" SAE male connectors for easy connection and disconnection. The integrated safety sleeve holds the coupler securely to the service port, ensuring your safety while in use. Additionally, the kit includes can tap tools made of cast aluminum and 1/2" ACME male and female connectors, along with a solid brass R22 to R410a adapter with 1/2" ACME female to 1/4" SAE male, allowing for quick and safe switching between different refrigerants.
- MANUFACTURER WARRANTY & 7/24 SERVICE： Your purchase of this A/C diagnostic manifold gauge set is fully covered by a 1-year limited manufacturer warranty and our professional 7/24 customer support team from our USA based company with over 30 years of experience in the HVAC industry. We prioritize our customer's satisfaction above all else and are committed to providing the best possible service to you.

## Questions & Answers

**Q: Where are the valves on the coupler? Instructions say the couplers have valves but I see none.**
A: There are two types of adapters, those with valves which also push down the schrader valves when opened, and the automatic ones which my kit came with. Sometimes a bit tricky to couple up, and gas can vent while trying to align and seat these couplers, but a few tries and you will sort it out. The valve types are easier. The instruction book is rubbish, watch some YouTube vids instead. Remember to purge the lines before connecting to car: Connect a can of gas to the yellow line, then open the valve on it and one at a time loosen adapter from a blue or red line slightly, and then open manifold valve slightly until gas escapes. Close manifold valve and re-tighten adapter. Repeat for other side. If you don't do this, you will push air & moisture into the system when charging the system. Best to wear safety glasses and maybe gloves when messing with Freon. Good Luck!

**Q: How long are the hoses? Do not see it in the description.**
A: The hoses are 4 ft long for each.

**Q: How long are the hoses?**
A: 48 inches

**Q: case only for guage set price**
A: Don't understand your question, but mine was case and guages.
