It details thread specifications for various standard fitting types, including female flare, male insert O-ring, male O-ring, and female O-ring configurations. The data is organized by industry-standard numbers (No. 6 through No. 12) and their corresponding physical thread measurements. This guide assists technicians in identifying and matching the correct A/C components for repairs, specifically addressing common sizing variations found in GM/IHC systems and dryer fittings. It serves as an essential manual for professionals ensuring secure and accurate installation of automotive climate control systems.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/ac-hose-fittings-thread-size-chart-tech-tip-137/563796/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/ac-hose-fittings-thread-size-chart-tech-tip-137/563796.png","ImageObject",442,249,{"name":42,"@type":43},"Nguyễn
