Don’t Let Leaky Fittings Bring Your Fleet To A Screeching Halt!

Fittings that leak or do not properly retain tubing can cause many significant problems for your fleet.

  • Excess compressor use
  • Suspension issues
  • Improper air control function
  • and even full release of tubing

These can lead to DOT fines and even worse, idle assets that cause you to miss deliveries creating customer disappointment and loss of revenue.

Protect your income stream and your hard-earned reputation by using a better fitting!

Choose Alkon’s DOT Fittings

Alkon helps you stay ready for the many miles of road ahead.


Alkon’s DOT fittings are designed to provide maximum tube retention, while still allowing for proper release during maintenance procedures. Alkon’s fittings grip the tube well beyond the DOT specification. Our gripping teeth are deeper than our competition yet still allow for an easy release.


Alkon has the right amount of squeeze between the seal and the tubing surface allowing for a dependable leak-free fitting. Alkon also has a deeper insertion depth beyond the seal allowing for a greater miss-cut angle on the tube.


Alkon’s floating tube support is longer than the competition supporting the tube all the way through the fitting. Our floating tube support is self-centering allowing for a much greater side load preventing any leakage and allowing for greater bend radii when routing tubing.

Positive Seal

Tube support area beyond O-ring exceeds that of all competitive products, compensates for bias cut tubing, and dramatically reduces troubleshooting time.
