Description

Overview

The 3/8 x 3/8 NPTF female connector joins 3/8-inch OD nylon air-brake tube to a 3/8 NPTF male-threaded component. Its straight brass body maintains the tube direction. Unlike its 1/4-thread counterpart, this fitting accepts the larger male port.

Features

• Push-in collet grips 3/8-inch OD tube.
• Female 3/8 NPTF pipe thread.
• Brass hex body for tightening.
• Integral tube support and O-ring seal.

Specifications and Materials

The assembled brass fitting incorporates its release collet, tube support and sealing components. The push-in end needs no separate compression nut or sleeve.

Part number: DQ66DOT0606.
