Inner tube assembly
Inner tube assembly
LumenInternal coating is applied to metal tubing to add lubricity, chemical isolation, or surface preparation to the tubing inside.
The Inner tube is designed for internal coating applied to metal tubings like Torque coil, ACT ONE, or Wire coil for adding lubricity, chemical isolation, or surface preparation to the inside of the hollow cable. Ideal for applications requires lumen lubricity, sealing, or chemical resistance, for customers developing a delivery system.
Minimum wall thickness (including Fluoropolymer and PEBAX layer)
Coating material (Fluoropolymer layer)
- PTFE greatest lubricity and chemical resistance
- PFA similar in chemical resistance to PTFE, but less lubricity
- FEP similar to PFA, slightly less susceptible to water absorption than others
- ETFE greatest strength and abrasion resistance
Length: up to 1800mm (Trial : up to 3000mm)
End treatment of inner tube: manually cut using a utility knife
End treatment of outer cable: EDM cut, chamfering
