We stock a full range of sizes, and can custom manufacture for you. Call our customer service department at 800-519-3688 for details, or email us at customerservice@nmrtubes.com with your questions.

Thin-Wall Transparent Fluoropolymer FEP Tubing
Our thin-wall transparent fluoropolymer FEP tubing is manufactured from special virgin grade DuPont thermoplastic FEP fluoropolymer. Unlike PTFE tubing, this material can be heat sealed.
PTFE Tubing
The recommended choice for temperature requirements ranging up to 500º F (260º C), It resists “melt-off” by soldering irons when making terminations.
PVDF Tubing
An abrasion resistant fluoropolymer suitable for use in applications requiring chemical resistance with low permeability. It provides excellent chemical resistance.
PFA Tubing
Offers excellent crack and stress resistance.The product of choice for applications involving extreme chemical resistance combined with high temperature exposure.
FEP Tubing
The preferred material in production of small diameter tubing of continuous lengths. Its chemical and dielectric properties are similar to those of PTFE.
