Car Air Conditiioner Gauge and Hose by InterDynamics, A/C Pro Air Conditioner Recharge Gauge and Dispenser for Cars, Trucks, 24 In Hose

Just what I needed to fix the AC in my truck. Super simple and easy to use. Hook it up to your vehicle with a can of refrigerant while on max AC, check to see where the gauge is, pull the trigger while moving the can from upright to sideways and back until the gauge is in the 40-50 range and you're good to go. I'm back to ice cold AC, just in time for summer!

This 134a gauge is the best tool to add coolant to a vehicle's a/c system that I have ever used. I used a resealable can to top off my two vehicles this morning both at 40 psi in about 10 minutes. Just follow the instructions on the package and save yourself big bucks. It's easy and safe.

works well...help me recharge a slightly low system quickly ..will buy regular gauges eventually

Why did you pick this product vs others?:It was recommend by a store employeeEase of installation:It was incredibly easy to use, It just push snap into place on the charging port and pull snap off when done. The locking function is flawless and there are no leaks.

This pump is very easy to use. Simply screw on the can and press the lever while the AC is on full blast. It fits the $10 cans that you find at most retail stores.

Works good for a simple refill of a car. Let’s say you’re just topping off your Freon, this could save you a lot of money. I would recommend the national brand r134a Freon. It works fantastic. It’s a metal braided hose with silicone underneath. It should last a while. Fits perfectly. The temperature gauge works good and fairly accurately. And best of all, no leaks at all coming out.

Well got the digital gauge by mistake from Amazon so thumbs down for Amazon. I ordered the non-digital gauge because of my doubt over longevity of digital and reliance on battery... but I needed to fix AC ASAP since it was extremely hot and muggy out, July in New England!... so despite my reluctance I decided to try it. Used it 2 times for a total of about 10 mins... turned it off when stored and made sure battery was not being accidentally turned on and it's dead now. Called InterDynamics and explained the problem and they said they have no warranty for their gauges and that it's likely a battery issue... so I have to take pics of the battery and submit it to energizer for a "Possible" new battery, and I have no idea how long that will take even if I do get a replacement battery. I need it now since my AC still needs tweaking to operate it optimally during the worst months of the year. I told them that if the battery was new, indicated by the fact that I had to pull out the plastic tab that kept the battery from being drained during storage and shipment that the battery was probably not the issue, but they don't see it that way. Even after I told them I had pretty varying pressure readings from first reading to second reading... and I know it can vary but still makes me wonder. I wanted them to replace it with the non-digital version but I got nowhere with that. Last A/C Pro product I'll buy... they are overpriced anyway and I only bought this one since I just happened to find it discounted on Amazon that day.

Worked Great for my DIY freon refill project. Its a great quality product, easy to use. Love the price.
