Description

Overview

The 3/16 x 1/8 NPTF female connector joins 3/16-inch OD imperial nylon air tube to a 1/8 NPTF male threaded component in a straight line. One end uses a push-to-connect collet for the tube, while the opposite end provides the female pipe thread. This layout suits compact pneumatic connections where a tube must terminate directly at a threaded valve, manifold or other compatible port.

Features

• 3/16-inch OD push-to-connect tube connection
• 1/8 NPTF female pipe thread
• Straight brass connector body with installation hex
• Reusable collet allows tube removal during servicing

Specifications and Materials

Product type: DOT push-to-connect female connector. Tube connection: 3/16-inch OD imperial tube. Thread connection: 1/8 NPTF female. The brass body combines the push-in tube end and threaded end in one compact fitting, so no separate adaptor is needed between these connection types.

Part number: DQ66DOT0302.

Compatibility and Fitment

Confirm the tube outside diameter and thread before ordering because both dimensions are selection-critical. The push-in end requires 3/16-inch OD tube, while the threaded end accepts a 1/8 NPTF male connection. Do not confuse this part with a male connector, which places the pipe thread on the outside of the fitting. Also check that the tube enters the collet straight without side load.

Compliance and Safety

This fitting family is approved to meet ADR 38/05, DOT FMVSS 571.106, SAE J2494/3 and SAE J1131. Before installation, depressurise the circuit and cut the tube square. Remove any scored, flattened or damaged tube section, then push the tube fully into the collet. After restoring pressure, inspect both the push-in joint and threaded connection for leakage.

Trailer Applications

The 3/16 x 1/8 NPTF female connector suits compatible truck and trailer pneumatic circuits where a small imperial air line must connect directly to a male threaded component. It can serve air brake, air suspension and auxiliary air plumbing when the connection sizes and system requirements match.

Why Choose ICS Trailers

ICS Trailers supplies air fittings for trailer pneumatic repairs where tube size, thread type and connector gender must all match. If the old fitting has unclear markings, compare the tube OD, thread diameter and whether the threaded side is male or female before ordering.
