This sleeve fits over PEX-A tubing during the expansion fitting process, creating a secure, leak-resistant connection when the expanded tubing and sleeve contract back around the fitting. It is a standard component in F1960-compliant cold-expansion PEX systems and is installed by licensed plumbers in both new construction and retrofit plumbing applications.\u003c\/p\u003e\u003cp\u003eThis sleeve is intended for 1-inch PEX-A tubing systems that follow the ASTM F1960 cold-expansion connection method. It is used in residential and light commercial water distribution systems, including supply lines for domestic hot and cold water. The F1960 expansion method requires matching-size sleeves and fittings, and this part is sized for 1-inch nominal tubing installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSized for 1-inch PEX-A tubing per ASTM F1960 specifications\u003c\/li\u003e\n\u003cli\u003ePolyethylene construction compatible with potable water applications\u003c\/li\u003e\n\u003cli\u003eCold-expansion sleeve design requires no solder, crimp tools, or open flame\u003c\/li\u003e\n\u003cli\u003eForms a strong mechanical connection as expanded tubing contracts over the fitting\u003c\/li\u003e\n\u003cli\u003eConforms to F1960 cold-expansion fitting standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-inch ASTM F1960 PEX-A expansion fittings and 1-inch PEX-A tubing.
