Capillary tubing technical knowledge center
This knowledge center organizes capillary tubing content by buyer question: how to choose material, how to compare OD and ID, how wall thickness affects sourcing, when secondary processing is needed, how to prepare an RFQ, and how to evaluate a supplier.
Key points for buyers and engineers
- Start with the size database when you already know OD, ID, or wall thickness.
- Use material guides when choosing between 304, 316, 316L, or titanium-related components.
- Use processing guides for laser cutting, deburring, cut length, and finished tube parts.
- Use RFQ guides when preparing a quote request for supplier review.
