Midland Industries 32153 Double Mini Barb Male Adapter

Product Description

The MIDLAND INDUSTRIES 32153 is a double mini barb male adapter designed to connect plastic tubing to threaded pipe systems. One end features a 3/8-inch double mini barb connection that grips plastic tubing securely without clamps. The other end is a 1/4-inch male NPTF threaded connection for leak-free tapered thread engagement. Constructed from brass, this adapter handles a maximum operating pressure of 150 psi and an operating temperature range of -65 to 90 degrees F. Plumbers and mechanical contractors install this fitting when transitioning flexible plastic tubing lines to rigid threaded fittings in fluid-handling assemblies.

This adapter is suited for residential and light commercial plumbing and fluid transfer applications where plastic tubing must interface with NPTF-threaded ports. Typical installations include low-pressure water, air, or fluid lines routed through equipment panels or plumbing assemblies. The double mini barb profile provides a secure grip on the tubing wall, reducing the risk of pull-out under normal operating pressures. This fitting is intended for use with plastic tubing only and is not rated for metal or rubber hose assemblies.

Key Features

• 3/8-inch double mini barb inlet grips plastic tubing without requiring a separate clamp
• 1/4-inch male NPTF thread provides a pressure-rated tapered thread seal
• Brass construction offers corrosion resistance in water and fluid service
• Rated to 150 psi maximum operating pressure
• Operating temperature range of -65 to 90 degrees F suits a wide range of service environments
• Compact form factor fits tight installation spaces

Compatibility

Designed for use with plastic tubing. Connects to any 1/4-inch female NPTF-threaded port. Suitable as an OEM-style replacement or new-installation fitting in low-pressure plastic tubing systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Depressurize and drain the line fully before removing or installing any fitting. Apply an appropriate thread sealant or PTFE tape to the male NPTF threads before assembly. Do not overtighten; NPTF tapered threads seal through thread interference and excessive torque can crack brass fittings or damage mating ports.
