Useful answers before you specify.
01What information should I provide for a tubing enquiry?
Share the target outside diameter, inside diameter or wall thickness, dimensional tolerances, required length or roll format, colour, resin or compliance needs, operating conditions and estimated quantity. A drawing is helpful for custom requirements.
02Which catheter tube gauges are available?
PTFE catheter tubes are offered in 14G, 16G, 17G, 18G, 20G, 22G, 24G, 26G for IV cannula, diagnostic and surgical equipment applications. Confirm dimensions for the selected gauge.
03What are the core performance benefits of PTFE tubing?
PTFE offers strong chemical resistance, a broad operating-temperature range, low friction, a non-stick surface and excellent resistance to weathering. Suitability must still be confirmed against the conditions of the specific application.
04What standard tube sizes are available?
PTFE tubes and liners are offered with an OD of 1.00–6.00 mm and wall thickness of 0.20–1.00 mm. Inner diameter, dimensional tolerances and custom sizes are confirmed against the application specification.
05How can the product be supplied?
PTFE tubes can be supplied in continuous lengths. Cut-to-length supply is available on request, and packaging can be discussed against production and handling requirements.
06Which material compliances are available?
Our fine-powder selection process supports grades compliant with FDA 21 CFR 177.1550, relevant EU food-contact regulations, RoHS, REACH and USP Class VI requirements. PFOA-free material options are also available.
07How are dimensional tolerances confirmed?
The published ranges are a starting point. Final tolerances depend on the selected dimensions, resin properties and application requirements, and should be confirmed in the approved specification before production.
08Can non-standard dimensions or colours be produced?
Yes. Natural is the standard colour, while other colours and additional dimensions can be developed for qualified requirements. Contact our technical team with the target specification and expected volume.
