4 different dimensions of connector tube:

• 2mm ID and 3mm OD
• 3mm ID and 4mm OD

PTFE is a thermoplastic polymer, generally also known as Teflon.

Teflon has a high temperature and electrical resistance, resistance to acid and alkali, anti-stick wear-resistant properties.

These Teflon tubes are an instant upgrade for any 3D printer setup, as the extremely low friction tubing material allows the filament to travel smoothly between the extruder and the hot end, preventing clogging and issues with under-extrusion.

This Teflon tube for connecting the filament from the motor to the extruder and the original steel cell in the hot end block, can withstand temperatures from as low as -180C to as high as 260C.

The Bowden connector tubing has a maximum pressure of 8 kgs/cm2, and a density of 2.15-2.20g/cm3.
