Tackling an air conditioning repair or recharge on an older car with an R12 system? This Glarks 71-piece kit is a super handy assortment of the small but crucial parts you often need. It's like a toolkit for your A/C system's seals and valves. Inside the organized plastic case, you'll find: 10 brass valve cores, 10 R12-style valve cores, 20 green hose gaskets, 30 black hose gaskets, and one double-headed valve core remover/installer tool. The gaskets are made to be oil-resistant, corrosion-resistant, and provide a good seal to prevent leaks. The metal remover tool (blue, about 3 inches long) makes removing and installing those tiny valve cores a snap. This kit is designed for universal use on most vehicles, specifically for maintenance on R12 air conditioning systems (common in older cars). It's perfect for DIY mechanics or professionals who want to have a selection of common seal replacements on hand to avoid downtime. Remember, this is for parts and tools; please ensure you have the proper knowledge and equipment for safe A/C system service. If you receive the kit and anything is damaged or missing, just email us and we'll sort it out promptly.
