Connector — Straight Push‑to‑Connect 3/4" Tube × 1/2" MPT (Freightliner 23-14392-015)

Overview
The Freightliner part 23-14392-015 is a straight push‑to‑connect (PTC) male connector designed to join 3/4" OD DOT/air tubing to a 1/2" MPT (male pipe thread) port. It’s intended for pneumatic and brake system service fittings where a quick, tool‑free push‑in connection to tubing is required while providing a standard 1/2" pipe thread for attachment to ports, adapters or hose fittings.

Features

• Straight connector with push‑to‑connect tube end for fast tube insertion and release.
• 1/2" male pipe thread (MPT) on the opposing end for common plumbing/port connections.
• Designed for DOT/air tubing and vehicle pneumatic applications where 3/4" OD tube is used.
• Suitable for rapid service and repair — eliminates flaring or mechanical clamps on the tubing end.
