So I can't remove one to check the thread size and pitch (I do have a thread gauge). However, these will work for any service port that's for the 134A refrigerant. BTW, these worked perfectly! The beauty of these is they are cheap and it prevents you from having to pull a vacuum and replace the dryer and Schrader valves. If you were to service the Schrader valves you would need to evacuate the refrigerant (pull a vacuum) and as soon as you remove the old Schrader valves to replace them, the entire system becomes contaminated with moisture which destroys the desiccant in the dryer. At that point, you're better off replacing the high/low pressure lines, dryer, and the expansion valve/orifice. This tiny brass fitting eliminates all that trouble and saves you between $200 and $400 of heartburn. **Q: Is this fit low pressure service port ?** A: Don't know what vehicle you are wanting to use this on but on a GM it only fits the high pressure side. I used it on a 99 Tahoe with a substantial leak. So far it has done the job. Beats changing out the port and having to open the system, vacuum and refill with freon. **Q: what is the size in inches 1/8 3/16 or 1/4** A: This is 11mm hex which is lust under 7/16. Thread is 5/16-24 **Q: Do i need to add an o-ring, or will it somehow seal without cranking it down into the port?** A: You don't need to add an O ring. You take the plastic cap off and thread this one on in place of the cap. If you ever need access to the port, just take this off as you would if it had the plastic cap. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gmt800 ac fix *by J***R on September 24, 2025* Saved me hundreds in repairs.
