The RAPID LOCKING SYSTEM 3091101010111 is a 5/8-inch tee fitting designed for use in piping and tubing systems that require fast, secure connections. Tee fittings split or combine flow at a branch point, making them a standard component in refrigeration lines, HVAC tubing runs, and related plumbing assemblies. This fitting ships as a single unit and is sourced directly from RAPID LOCKING SYSTEM, allowing technicians to match the exact part number for service and replacement work.
This tee fitting is suited for trade professionals installing or servicing systems that use 5/8-inch tubing. Typical applications include residential and light commercial HVAC refrigerant line sets, hydronic piping branches, and other fluid-handling assemblies where a branch connection at the 5/8-inch size is required. It is sold individually, making it appropriate for single-point repairs as well as larger installations requiring multiple fittings.
Designed as an OEM-style replacement tee fitting for systems using 5/8-inch tubing connections.
Installation should be performed by a qualified HVAC technician or plumber familiar with the applicable system type. Always isolate and depressurize the line before removing or installing any fitting. Follow applicable mechanical codes and manufacturer instructions for joint preparation and connection method. Verify the tubing size and fitting type before installation to ensure a proper seal.
