Midland Industries 26180L Captive Sleeve Male Adapter Brass

Product Description

The MIDLAND INDUSTRIES 26180L is a captive sleeve male adapter designed to connect 1/4-inch compression tubing to a 1/4-inch male NPTF threaded port. The captive sleeve design keeps the compression sleeve retained on the fitting body during handling and assembly, reducing the chance of lost components on the job. Constructed from brass, this adapter handles a wide service temperature range of -65 to 250 degrees F, making it suitable for gas, refrigeration, and instrumentation lines where a reliable mechanical compression-to-thread transition is required. Plumbers, HVAC technicians, and instrumentation installers are the primary trades that use this fitting.

This adapter is commonly used in residential and light commercial plumbing, HVAC refrigerant piping, and instrumentation tubing systems where copper or soft metal tubing must terminate at a threaded male NPTF port. Typical installations include gas appliance connections, pressure gauge lines, and control tubing runs. The compression end accepts standard 1/4-inch OD tubing, while the NPTF male thread provides a dry-seal connection to a female-threaded port or valve body.

Key Features

• Captive sleeve design retains compression sleeve on the fitting body for easier handling and assembly
• 1/4-inch compression inlet connects to standard 1/4-inch OD tubing without soldering or flaring
• 1/4-inch male NPTF outlet provides a dry-seal threaded connection to female NPT ports
• Brass construction offers corrosion resistance and durability across a broad temperature range
• Service temperature range of -65 to 250 degrees F suits refrigeration, gas, and instrumentation applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4-inch OD compression tubing terminated at a 1/4-inch male NPTF threaded connection in plumbing, HVAC, and instrumentation piping.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and IFGC requirements. Shut off and depressurize the line before disassembling or installing any compression fitting. Ensure tubing ends are cut cleanly and deburred before inserting into the compression end. Do not overtighten the compression nut, as brass fittings can be damaged by excessive torque.
