This wide compatibility makes the 40mm barrel a versatile choice for maintenance and upgrades.


Important Specification Notes


  • L/D Ratio: The barrel length corresponds to a 20:1 or 22:1 ratio, which balances melting efficiency and injection speed for mid-range tonnage machines.

  • Mounting Flange and Heater Band: While the diameter and length are fixed, verify the bolt hole pattern on the mounting flange and heater band locations before ordering. These details can vary slightly between FN and NEX series machines, affecting fit and installation.
