Frequently Asked Questions
How do I choose the correct cap size for my tube?
Measure the outside diameter of your tube in millimetres and select the cap size that matches this dimension, for example 8.2 mm, 11.3 mm, 14.53 mm, 21.29 mm, or 28.73 mm. The caps are designed to push-fit over the outside of the tube, so an accurate outside diameter measurement is essential for a tight, secure fit.
Are these PETG caps suitable for use with food or pharmaceuticals?
The caps are manufactured from PETG, a widely used packaging plastic. However, specific suitability for direct food or pharmaceutical contact depends on the regulations and approvals required for your application. Please check compliance requirements and request any necessary material information before using them in regulated environments.
Can these caps be reused after removal from the tube?
Yes, the push-fit design allows the caps to be removed and refitted, and they can typically be reused provided they are not damaged and remain a snug fit on the tube. For best results, inspect caps for wear or deformation before reuse, especially in demanding or repeated-use applications.
