Yes, Trajan does extrude custom sizes of PEEK tubing. Minimum order quantities and setup charges apply.
Standard industry colors are used to identify inner diameter (ID) size of PEEK tubing.
Non-leachable colorant is used for PEEK tubing.
The maximum temperature rating for PEEK tubing is 100°C.
The maximum operating pressure (size dependent) for PEEK tubing is 7,000 psi (483 bar).
Standard configuration tubing is supplied in 5', 10', 50' and 100', 250' and 500' lengths and rolls up to 3000' continuous length.
Most solvents including strong acids and bases can be used with PEEK tubing.
Dimethyl sulfoxide (DMSO), methylene chloride, and tetrahydrofuran (THF) will cause mild swelling. Concentrated nitric and sulfuric acids will degrade PEEK.
Yes. Stainless steel (SS) fittings are fine to use on the 1/16" OD PEEK tubing, keeping in mind that the smaller IDs can close up if you tighten the SS fittings too tight. Care should be taken to test and validate that your flow rates or chromatography are not negatively impacted.
Yes. If using 1/16" OD PEEK tubing, then you will want to use a two piece fitting such as the PEEKLok fitting as increased force is required for the PEEK tubing to bite onto the fused silica tubing. The sleeves will hold to 6,000 psi.
The maximum temperature rating for PEEKsil is 100°C.
We do not recommend cutting PEEKsil tubing. This is because during cutting the fused silica can break and block the tubing with small pieces of glass.
The maximum temperature for continuous use is 500°C. Once you get above about 600°C the glass layer will start to soften, so that it might be deformed by any pressure.
Above about 500°C, the strength of the stainless steel will also be reduced.
300 μm is the minimum ID.

We are unable to use quartz glass in GLT instead of borosilicate glass for the following reasons due to the differences in melting points of stainless steel and quartz glass. The stainless steel tubing will be affected by the temperature required to soften and melt the quartz.
