PEEK Tubing

About PEEK Tubing

PEEK tubing (a non-fluoropolymer) is well known for its very high degree of hardness even at elevated temperatures. Such tubing enjoys resistance to extremely high pressures and in many cases has replaced stainless steel. Due to its high purity, PEEK tubes do not leech out damaging ‘extractables’ and is very effective in the trace analysis of complex fluids.

PEEK tubing is flame retardant and exhibits very low smoke emissions lending itself well to wire and cable sleeving in aerospace applications. Being compatible with high doses of radiation, a PEEK tube resists embrittlement, maintaining mechanical integrity in the most demanding environments.
