This ATCO Bead Lock Steel Step Up adapter provides a robust solution for stepping up A C line connections from size 8 to size 10 while maintaining a reliable O ring seal. Built for use in air conditioning and refrigeration systems, the bead lock design secures hose assemblies and prevents slippage under pressure. The female O ring interface delivers a positive seal when mated with compatible male fittings, reducing the risk of leaks in critical cooling circuits.

Constructed from durable steel with a protective finish, this step up fitting is intended for professional and DIY A C plumbing tasks where a secure, leak resistant connection is required. It is suitable for joining hoses and hard lines where size conversion is needed; always use the Parts Checker to confirm compatibility with specific vehicles or systems before purchase. Installation should follow manufacturer guidelines and use appropriate clamps and O rings as required by the system.
