Frequently asked questions

Find answers to common questions about our products and services
  • The inlet is a 3/4" barb fitting, designed to connect to standard 3/4" barbed DEF dispensing systems and pumps.

  • No nozzle is included. The hose terminates in a 3/4" cut hose end with a hose stop, so a separate DEF-compatible nozzle or fitting will need to be attached before dispensing.

  • Two black hose clamps are included to secure the barbed connections at the hose ends — no additional fastening hardware is required for the hose connections themselves.

  • The hose stop is a fitting at the open end of the hose that prevents the hose from retracting fully into the reel, keeping the end accessible and in place when the reel is in use.
