Lot of 26 3/4" PEX-A Barb x 3/4" PB Barb Transitional Coupling made by Apollo PEX.

This fitting is used to connect two different types of plumbing pipe: • PEX-A Barb (Cross-linked Polyethylene): This is a type of PEX piping that often uses an expansion connection method (like the ASTM F1960 standard mentioned on the bag) where a sleeve is expanded with the pipe and then shrunk back down over the barb fitting. • PB Barb (Polybutylene): This is an older, now-discontinued plastic piping material. The coupling allows you to create a transition between an existing Polybutylene (PB) plumbing system and a newer PEX-A system, which is a common scenario when repairing or replacing sections of older plumbing. Key takeaways from the packaging: • Size: 3/4 inch on both ends. • Type: Transitional Coupling. • Connection Method: Uses barb fittings on both sides. • Standard: Meets ASTM F-1960 standards (which is the standard for cold expansion PEX connections). • Installation Note: The package explicitly states, "Must use an Expansion Sleeve for installation", confirming the PEX-A side is designed for the cold expansion connection method.
