DOT Fittings

UPC is fully stocked on DOT approved fittings for air brake systems in commercial motor vehicles. We offer DOT fittings in several styles, including Straight, Elbow, Tee, Union, Bulkhead, Tube to Stem and Y DOT fittings.

Push to Connect DOT Fittings

Push-to-connect fittings have ends that are designed to accept tubing by pushing it into the end. These fittings typically disconnect via some type of collar retraction. These fittings are easy to install and require less maintenance than compression fittings.

Compression DOT Fittings

A compression fitting is a 3 pcs fitting containing a Nut, Farrell, and Body. Compression fittings can support a higher PSI rating and are less expensive than Push to Connect fittings.

DOT Nylon Tubing

DOT Nylon tubing is essential in maintaining an effective air brake system in trucks, trailers and auxiliary air systems. Our selection of DOT tubing has a working pressure of 150 PSI and meets or exceeds DOT FMVSS 571.106 & SAE J844 standards. This double-walled, nylon covered tubing can hold up to damaging environments and offers the following benefits:
  • Heat and light aging resistant
  • UV & Ozone Resistant
  • Gasoline & Diesel Fuel resistant

DOT Drop Coil Tubing Supplier

Our offering of single-drop and multi-bore drop polyurethane coils are available in multiple diameters, lengths and colors. These UV stabilized coils are resistant to abrasion, overstretching and kinking. The retractability of these coils make them perfect for applications with highly repeatable flexing processes. Working length, retracted length and tail length should be considered prior to choosing the overall length of your coil.

Flexeel® Polyurethane Reinforced Hose is extremely lightweight and tough. It is ideal for either outdoor or indoor use. Flexeel® retains its flexibility even in cold environments. This tubing is UV stabilized with a vacuum rating up to 28” Hg. Additional features include:
