Four Seasons 26783 Cap & Valve Air Conditioning System Seal Kit

Perfect fit!!! This is a 2000 Honda Odyssey EX. For some reason this minivan lost all the freon. I didnt know where the system was leaking. So I added freon to the system and I noticed that it started leaking from the low pressure valve. So I decided to buy these valves and caps. I changed both, low and high pressure valves with a new cap. They did solve my leaking problem. Now my AC is working great. After 16 years of use, the minivan it is cold enough here down in Mexico. I live in a tropical place. Very happy and I did it myself. Thank u!!!!

Very nice little set of valve cores. The low-side valve core on my 2006 Toyota 4Runner was leaking so I bought this kit to replace it. Admittedly, prior to this you could have taken all my automotive AC repair knowledge and fit it in the belly button of a lady bug, but I was confident enough that one of sizes of valve cores in this kit would fit so I rolled the dice and purchased it.As it turns out, my low-side valve core was a “JRA” style fitting (the fatter looking of the cores shown in the picture). These size cores are also called “GA 1531” style valve cores. I’m not even going to even try suggesting that this kit will work on your vehicle (unless you have a 2006 4Runner) since I’ve read enough reviews to know that there are a lot of different style valve cores and most vehicles take different size fittings for the low-side and high-size valves. But, will tell you that you can check out polarbearinc.com/Webstore/index.cfm?fuseaction=category.display&category_ID=80 and this site has a pretty good page that shows the different types of valve cores which may help you figure out what you need. I can tell you that this kit comes with two GA 1531 (or JRA) cores and two GA 1528 (standard flow) cores.Anyway, I purchased a separate tool (Mastercool 58531) to install the core without losing any refrigerant and this fixed my leaky valve.

I noticed that my 2006 Honda civic was leaking at the low side ( Noticed when I opened the valve cap and hear a quick hiss ). My AC was not cooling at low RPM and gauge was reading almost or near overcharged. I guess due to over filling with Freon or air ( empty can ) . I basically removed the low side ( Using the big valve of the kit ) using a long valve remover tool ( bike valve tool is too short ). Also did High pressure side just in case ( Thin valve in kit - I think but check size when removed ). Once installed I connected a small can of R134a on low side filling AC while depressing High side valve to purge out the air in the system ( about 5-7 sec ). Now I believe I used 1 1/2 cans of Freon and got to about 43 psi ( Green area on gauge ). Now I can survive these 90 degree weather. lol

I used this kit on a 2003 Sentra which has JRA valves. The kit has a pair of JRA and a pair of standard size valves, plus a bunch of different size caps. I used the Masterwork 58531 kit to replace the valves with the system still holding some pressure.At first the high side valve didn't made a tight seal the first time I tried inserting it and I could see bubbles coming from it. I thought it was broken so I removed it and tried the second new one in the kit - same problem. So I put the tool on again and pressurized it, then removed it so the pressure changed more rapidly, forcing the valve to seat property, causing the leak to stop. Once I had this figured out things went smoothly and they also worked fine with my manifold recharging the system.

I liked that this contained both large and small shrader valves in brass, rather than steel. And it included 4 different sizes of H/L pressure caps. I would buy this again.

These were a perfect fit for both of my low and high pressure a/c lines on my 1996 Honda Civic EK hatchback. I previously purchased a different set of caps on amazon but the high pressure cap didn't fit. This kit is convenient because there are multiple types of caps for both high and low pressure. Appear to be durable enough for it's main purpose.

I often used the Amazon "my garage" option to find and buy parts for my truck. It showed green and said this would fit. Most of the time it is right but not this time. The little kit is nicely made. They look like quality parts, they are just the wrong parts for my truck. Anyway, don't believe the my garage check - if they don't look like your part then don't buy them.

The small light blue caps are the ones that were a perfect fit for my 2010 Infiniti FX35. I didn't need to replace the valves but i still decided to try them and see if they fit. Out of the two set of valves, the bigger valves were a perfect fit for my Infiniti FX35. The only thing I did notice was the o-ring on the valves looked a bit slimmer compared to the o-ring on my original valve. Its still a great buy!

Funcionales

Exactly what I needed

Good value kit, the stems fit in the Mazda 2. The low cap fit on my ranger too which is an added bonus for me.

Red cap in pic is what i ordered. It threads on nice and snug to the high pressure line. 2006 civic 1.8l ex sedan.

No problems with installation.
