Midland Industries 19153L 3/8 Compression X 1/4 Fip Brass Adapter

Product Description

The MIDLAND INDUSTRIES 19153L is a brass female adapter body designed to connect a 3/8-inch compression line to a 1/4-inch female iron pipe (FIP) fitting. This compact adapter is used in plumbing and refrigeration tubing systems where a transition between compression and threaded pipe connections is required. The body is machined from brass for corrosion resistance and long service life. At 0.97 inches in length with a 0.62-inch hex, it fits standard wrenching without bulk. Plumbers and HVAC technicians install this fitting when joining copper or soft tubing runs to threaded FIP ports on valves, manifolds, or equipment.

This adapter is suited for residential and light commercial plumbing, HVAC refrigerant line accessories, and utility gas or water line connections where a compression-to-FIP transition is needed. The compression end accepts standard 3/8-inch OD tubing, while the 1/4-inch FIP thread end connects to male-threaded ports. Its small footprint makes it practical in tight service spaces such as under-sink installations, appliance connections, and equipment panels.

Key Features

• 3/8-inch compression inlet to 1/4-inch FIP outlet transition
• Machined brass construction for corrosion resistance and durability
• 0.62-inch hex allows standard wrench or adjustable-wrench installation
• Compact body at under 1 inch in length for use in tight spaces
• Female adapter category fitting for connection to male-threaded ports

Compatibility

Designed as an OEM-style replacement or new-installation brass compression female adapter for residential and light commercial plumbing and HVAC tubing applications requiring a 3/8-inch compression to 1/4-inch FIP connection.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off the water or gas supply and depressurize the line before working on any fitting. Apply thread sealant or PTFE tape to the FIP threads in accordance with applicable IPC or IFGC requirements. The compression end does not require sealant but should be tightened with a backup wrench to avoid overtightening the fitting body.
