Description

Overview

The 1/8 NPT x 1/4in nylon tube fitting joins 1/4in outside-diameter nylon air-brake tube to a female 1/8 NPT port. Its straight brass body keeps the connection compact, while pre-applied thread sealant prepares the male pipe end for installation.

This connector suits repairs where a small nylon line enters a threaded valve, manifold or pneumatic component. It includes the compression nut and preassembled tube insert required at the tube connection.

Features

• Straight connector for 1/4in nylon tube
• 1/8 NPT male pipe connection
• Brass body with installation hexes
• Includes compression nut and tube insert

Compatibility and Fitment

Match the tube outside diameter and pipe thread before ordering. The main mismatch risk is choosing a similar connector with a 1/4 NPT thread or a metric tube connection. For the 1/8 NPT x 1/4in nylon tube fitting, cut the tube square, remove burrs and push it fully into the body before tightening the nut.
