I previously purchased a different set of caps on desertcart 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. Review: Worked on 2006 Toyota 4Runner low-side - 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. ## Features - Four Seasons A/C System Valve Core and Cap Kit P/N:26783.Material:Aluminum - Part number: 26783 - Package Weight: 0.023 kilograms - Package Dimensions: 15.24 H x 1.778 L x 11.43 W (centimeters) ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Four Seasons | | Brand | Four Seasons | | Model | AC Seal Kit | | Item Weight | 0.01 ounces | | Product Dimensions | 5.75 x 2.63 x 1.75 inches | | Item model number | 26783 | | Is Discontinued By Manufacturer | No | | Exterior | Machined | | Manufacturer Part Number | 26783 | ## Images ![26783 Cap & Valve Air Conditioning System Seal Kit - Image 1](https://m.media-amazon.com/images/I/818TQBheKNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for EK Civic a/c lines *by O***S on November 2, 2023* These were a perfect fit for both of my low and high pressure a/c lines on my 1996 Honda Civic EK hatchback.

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.
