DOT Compression Air Brake Fitting-Nylon Tubing Male Adapter

DOT Compression Air Brake Fitting

Description:

DOT compression air brake fitting is a type of fitting used in air brake systems. The male adapters have a male NPT thread and are used to connect nylon tubing.

The use of compression connections allows for a secure connection to the flexible nylon tubing, which helps to prevent leaks and minimize maintenance requirements.

Send Topa your part numbers, tubing specifications, and quantities per size for product review and quotation. Include any required compliance documentation with your request.

Features and Benefits:

Tube-to-Port Connection: Connects compatible nylon tubing to a matching female pipe-threaded port.
Compression Tube End: Uses the specified nut, sleeve, and tube-support arrangement.
Straight Brass Body: An inline configuration for installations that do not require an elbow.
Separate Size Selection: Specify tubing outside diameter and pipe-thread size independently.

Description

The tubing size refers to its outside diameter. The pipe-thread size is a nominal connection designation and should not be interpreted as the thread’s measured outside diameter.
