Frequently Asked Questions

What is the difference between 2:1 and 3:1 heat shrink tubing?

A 2:1 ratio means the tube shrinks to half its original diameter when heated. A 3:1 ratio shrinks to one-third, allowing it to fit over larger components or irregular shapes.

Can I use polyolefin tubing in high-temperature environments?

Standard polyolefin tubing is rated up to 135°C. For higher temperatures, consider Viton, PVDF, or PFA/FEP tubing, which can withstand up to 260°C.

What are the advantages of adhesive-lined tubing?

Adhesive-lined (dual-wall) tubing creates a waterproof, airtight seal when heated, protecting against moisture, dust, and vibration — ideal for automotive and outdoor applications.

Do you offer custom sizes or colors?

Yes, we provide custom manufacturing for specific dimensions, colors, and performance requirements. Contact us for OEM/ODM support.

What is the minimum order quantity (MOQ)?

MOQ varies by product type and customization level. Standard items can be ordered in small quantities. Please inquire for details.
