The SLOAN 0308913 is a collar and sleeve stop assembly designed for use in commercial and institutional plumbing systems. This component controls flow and provides a secure stopping point within flush valve supply lines. It is built for 1-inch stop configurations and is typically installed by licensed plumbers or journeymen working on restroom fixture rough-in and service work. At 0.075 pounds, it is a compact, lightweight fitting suited for tight service spaces where precise flow control hardware is required.
This collar and sleeve stop is used in commercial restroom plumbing applications where Sloan flush valve systems are installed. It fits into standard 1-inch stop configurations commonly found in multi-stall restroom environments in schools, office buildings, healthcare facilities, and other high-use commercial settings. Service plumbers performing flush valve repairs or replacements will encounter this fitting as part of the supply stop assembly.
Designed as an OEM-style replacement collar and sleeve stop for Sloan flush valve plumbing systems using 1-inch stop configurations.
Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing code requirements. Shut off the water supply to the affected fixture before disassembling any stop or supply line components. Inspect the surrounding stop body and supply tubing for wear or corrosion before installing the new collar and sleeve. Do not overtighten collar fittings, as this can damage sleeve seating surfaces.
