Midland Industries 18534 1/4 in Hose Barb X Compression Adapter

Product Description

The MIDLAND INDUSTRIES 18534 is a brass compression adapter designed to connect a 1/4-inch hose barb to a 1/4-inch compression fitting. It serves as a transition connector in low- and medium-pressure fluid or gas lines where a barbed hose meets a compression-style tube connection. Built from brass, this adapter resists corrosion and handles operating temperatures from -65 to 250 degrees F with a maximum operating pressure of 300 psi. Its compact size makes it practical in tight installations. Plumbers, HVAC technicians, and gas service professionals install this type of adapter in equipment connections, appliance supply lines, and instrumentation tubing runs.

This adapter is suited for residential and light commercial applications where a hose barb connection must terminate or transition into a compression fitting. Typical install scenarios include equipment hookups, small-diameter tubing runs, and service connections on HVAC systems, refrigeration equipment, plumbing fixtures, and gas appliances. The 7/16-24 thread specification makes it compatible with standard fittings in that thread class. Its small footprint and moderate pressure rating make it a practical choice for confined-space connections in service and repair work.

Key Features

• 1/4-inch hose barb on one end, 1/4-inch compression on the other for direct barb-to-compression transitions
• Brass construction provides corrosion resistance and durability in fluid and gas service
• Rated to 300 psi maximum operating pressure
• Wide temperature range: -65 to 250 degrees F
• 7/16-24 thread specification for compatibility with standard fittings in that class
• Compact dimensions suit tight or confined installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for systems requiring a 1/4-inch hose barb to 1/4-inch compression transition in brass with a 7/16-24 thread configuration.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or gas service professional. Shut off the fluid or gas supply and relieve all system pressure before disconnecting any fittings. Ensure the compression nut and ferrule are properly seated before tightening to avoid leaks. Verify that thread type and size match the mating fitting before assembly to prevent cross-threading or fitting failure.
