Dorman 902-025 A/C Service Valve Cap

The Dorman 902025 A.C. Port Cap has received generally positive feedback from users. According to the frequently asked questions, the cap has been successfully used on a 2004 Chevy Avalanche and multiple other vehicles to fix leaks on both high and low-pressure ports for 134A refrigerant. Users have noted that it is a cost-effective solution, preventing the need to pull a vacuum and replace other parts of the AC system, potentially saving hundreds of dollars. Although there was a single user who reported that the cap did not seal a leak on the high-pressure port of a 1996 GM truck, they later found that the port itself had a scoring issue, and updated their review in acknowledgement of this. The majority of users reported successful sealing of leaks on high-pressure ports of various vehicles, including an 08 Trailblazer, and a father-in-law's vehicle. The installation process was described as simple, and some users emphasized that it does not require thread tape, as it is a brass compression type of fitting. In summary, the Dorman 902025 A.C. Port Cap has been well received by users, with many highlighting its effectiveness in sealing leaks and preventing the need for costly replacements in the AC system.
