The MIDLAND INDUSTRIES 30303 is a brass push-on hose splicer designed to join two lengths of 5/8-inch push-on hose in a single inline connection. Both ends feature push-on hose barb fittings, allowing fast, tool-free assembly without clamps in low-pressure fluid transfer applications. The fitting is rated to 150 psi and measures approximately 3.03 inches in length, making it a compact solution for tight installations. Constructed from brass, it offers good corrosion resistance in water, air, and compatible fluid systems. Plumbers, HVAC technicians, and general mechanical contractors install this fitting in a range of residential and light commercial applications.
This hose splicer is suited for inline repair or extension of 5/8-inch push-on hose runs in fluid transfer, low-pressure pneumatic, and general-purpose plumbing systems. It is commonly installed in residential water supply lines, irrigation laterals, HVAC condensate drain configurations, and similar setups where a quick, reliable hose-to-hose connection is needed without specialized tooling. The push-on barb design is intended for use with hose rated to accept a barbed connection at this diameter.
Designed as an OEM-style replacement or standard-service fitting for 5/8-inch push-on hose barb applications in residential and light commercial plumbing, HVAC, and fluid transfer systems.
This fitting is installed by plumbers or mechanical technicians working on low-pressure hose systems. Shut off the water or fluid supply and relieve system pressure before disconnecting any existing hose. Ensure the hose inner diameter is compatible with a 5/8-inch barb before assembly. Follow applicable IPC or local plumbing code requirements for the service type and fluid being conveyed.
