DOT BRASS PUSH-IN PNEUMATIC CONNECTORS

The Brass Push-in DOT Air Brake Fitting is strong, lightweight, impact-
resistant and can be used in the most demanding air brake applications.
Its push-to-connect design makes tube assembly fast and easy, no special
tools are needed to assemble. Tight internal tolerances ensure resistance to
contamination and optimal performance.
The push-in DOT design allows tubing joints to be made in just seconds
for high productivity during vehicle manufacture, maintenance, repair and
retro-fit installation. Tube assembly times can be reduced by 5 to 25 times
compared with traditional compression or swaged brake fittings.

Features and Benefits:
• Reduced assembly and maintenance times provide time/labour saving.
Connectors take only seconds to complete, eliminating the assembly of
nuts and sleeves, which is required when using compression fittings.
• Lubricated O-Ring Seal (Buna-N) insures a quick, easy and positive seal.
• Strong, lightweight and impact-resistant brass body.
• Complies with the requirements of DOT FMVSS 571.106 and SAE
Technical Data J2494 (inch) and DIN 74324 (Metric) air brake performance
