Product Details

The Tectran 66-4A is a brass female compression connector designed for use in heavy-duty air brake and pneumatic tubing systems on trucks, trailers, and buses. This fitting connects 1/4" OD nylon or poly tubing to a 1/8" NPT female-threaded port, providing a secure, leak-free seal in demanding transport applications.

Key Features:

  • Tube Size: 1/4" OD
  • Pipe Thread: 1/8" NPT (male)
  • Connection Type: Female compression fitting
  • Material: Rust-resistant brass construction
  • Application: DOT air brake and pneumatic systems on heavy-duty trucks, trailers, and buses
  • Built, assembled, and tested in-house for safety and optimum performance

Tectran compression fittings are engineered to withstand the most demanding heavy-duty transportation environments. The brass construction resists corrosion, and the precision-machined threads ensure a reliable, vibration-resistant connection in air brake lines and pneumatic circuits.

Easy shopping and straight forward!

Thank-you

Simple with the item in stock. At a good price! All good.

Shipping took longer than expected as I paid for expedited shipping. I reached out to ask why it wasn't sent two day and got no reply. The customer service could really use improvement and this is reflected in multiple reviews. However, the products arrived safely and as described. I'm very satisfied with the pricing as well. At the end of the day, that's the most important thing.

Shipped right away and arrived in good condition!
