EFFECTIVE SERVICE SET: This professional ac recharge kit by Orion Motor Tech includes a powerful 1/3 hp vacuum pump, 3-way manifold gauge, a leak detector, R134a self-sealing & puncture-style taps, R134a quick couplers, the necessary lubricating & absorptive pump oil, and 3 hoses for easy refrigerant evacuation, recharging, and other automotive AC repair work

DURABLE VACUUM PUMP: The motor’s high-quality copper construction offers efficient, dependable, and quiet service at a 4 cfm flow rate; the reinforced aluminum alloy casing effectively dissipates heat generated during operation and resists chemical corrosion for years of quality use

HELPFUL ACCESSORIES: This vacuum pump and gauge kit comes with an SAE adapter to allow use with 1/4", 3/8", and 1/2" hoses, 2 quick couplers and 2 taps for immediate use with self-sealing and puncture style R134a cans, and a durable case and bag to keep everything organized for storage and transport

The Easiest Injection Method: No more fussing with messy syringes, hoses, or pressurized cans. The Leak Saver injects directly and easily into the system with a basic manifold gauge set or even easier with our Leak Shot Injection Kits. Note: for automotive systems, you will still need the standard 134A to 1/4” charging adapter. Mini-splits may require a 5/16” to 1/4” charging adapter.

More Than 3 Million Units Sold Since 2015: The Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 72 hours. It’s similar to how blood in your body reacts to a cut. When a leak occurs, the Leak Saver reacts with the air and moisture at the leak site to permanently seal the leak. When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks.

With Added UV Dye for Finding Large Leaks: Seal it or find it! If you have a leak that is simply too large for leak sealants to seal, the added UV Dye will light up brightly at the leak site when using a UV flashlight.
