Hose & Tubing

Tubing Selection Guide

The best way to select a tube is to:
  • decide which materials are chemically suitable;
  • choose the one which best meets the physical demands of the application.
Normally, use the longest tube life material, which will usually be Bioprene or Marprene if they are chemically and physically suitable. Otherwise, silicone tubing is most often chosen for sizes up to 9.6mm, and Neoprene tubing for bore sizes of 12.7mm or more.
