The MIDLAND INDUSTRIES 30339 is a brass push-on tee fitting designed for fluid transfer applications where a hose line must split or merge at a single junction point. All three ports are 5/8-inch hose barb connections, allowing push-on hose assembly without threaded tools or clamp hardware at the barb interface. The all-brass construction provides corrosion resistance and durability in wet or chemically active environments. This fitting is sized and configured for use in plumbing, HVAC auxiliary lines, pool and spa equipment, and similar fluid-handling systems where a reliable tee junction is needed in soft or semi-rigid hose runs.
This tee fitting is suited for residential and light commercial applications involving water, coolant, or other compatible fluids routed through flexible hose. Typical install scenarios include pool equipment manifolds, HVAC condensate or water distribution lines, and general-purpose fluid distribution where 5/8-inch hose barb connections are specified. The push-on hose barb design simplifies assembly and reduces installation time in tight spaces or high-volume service situations.
Designed as an OEM-style replacement or new-installation tee fitting for systems using 5/8-inch push-on hose barb connections in plumbing, HVAC, pool, and fluid distribution applications.
Installation is performed by plumbers, HVAC technicians, or pool service professionals. Shut off fluid supply and relieve system pressure before removing or installing any hose barb fitting. Confirm hose inner diameter matches the 5/8-inch barb size for a proper interference fit; hose clamps are recommended to secure the hose to each barb port in pressurized service. Follow applicable IPC or local plumbing codes for fluid system assembly and material compatibility requirements.
