Product Overview

The SharkBite UA23103A25 is a 3/4-inch plastic expansion sleeve - sold as a pack of 25 - designed specifically for use with PEX-A piping systems. It enables secure connections to brass or poly expansion fittings, forming joints that become tighter and more reliable over time. Installation requires a PEX expansion tool (and matching expansion rings), after insertion, the chamfered sleeve slides onto the tubing and the built-in stop ensures proper positioning. Certified under ASTM F-1960 and ASTM F-877 standards, this sleeve is approved for potable water service lines, burial applications (including concrete encasement), and radiant heating systems - and offers long-term durability thanks to its corrosion-resistant plastic construction and cross-hatch interior that helps prevent sliding or loosening.
  • The sleeve is sized for 3/4-inch PEX-A pipe, ensuring a proper fit - this helps guarantee secure and leak-free connections when used with compatible tubing
  • The 25-pack gives you multiple sleeves in one purchase, making it cost-effective and convenient for larger plumbing projects or for having extras on hand for repairs
  • It is designed specifically for PEX-A pipe and expansion fittings, which ensures compatibility and reliability when used exactly as intended
  • Installation is simplified and tool-friendly - the sleeve features a chamfer for easy insertion and a "stop" that positions the ring correctly on the pipe, helping reduce installation mistakes
  • Once installed properly (using the required expansion tool and expansion ring), the connection grows stronger over time, meaning less chance of leaks or loosening as pipe systems age
  • The sleeve is made from high-quality PEX plastic, offering durability and resistance to corrosion, which supports long-term reliability
  • It is certified to standards relevant for plumbing use (e.g., for potable water systems and hydronic heating), making it safe for drinking water and various residential/commercial applications
  • The sleeve supports a wide operating temperature and pressure range - per specifications for expansion fittings using PEX-A pipe
  • Because no soldering or bonding agents are required (just the correct expansion tool), it reduces the need for special skills or messy installations - good for both professional plumbers and diyers
  • The expansion system is suitable for diverse applications - including potable water service lines, radiant-heating systems, and even direct-burial installations (e.g in concrete or underground), giving you flexibility depending on the project
