Frequently Asked Questions

Q: What does the size notation mean for these PTFE knife gaskets?

A: All dimensions are in millimeters. The format [OD × ID × Thickness] is used — for example, 13.5 × 6.2 × 0.5 mm means an outer diameter of 13.5 mm, an inner diameter of 6.2 mm, and a thickness of 0.5 mm. Please measure your knife's pivot/main shaft carefully before ordering to ensure a proper fit.

Q: Why use PTFE (Teflon) gaskets instead of metal washers for a folding knife?

A: PTFE gaskets are self-lubricating, meaning they naturally reduce friction between the pivot and blade without requiring additional oil or grease. They are also lightweight, corrosion-proof, and chemically resistant, making them an excellent choice for folding knife pivot assemblies where smooth, reliable action is a priority.

Q: Can I order a custom size not listed in the standard options?

A: Yes! These gaskets are offered as non-standard custom parts (Model AC-004). If you need a specific outer diameter, inner diameter, or thickness not shown, please contact us with your exact measurements and we will do our best to accommodate your requirements.

Q: How many pieces come in one lot?

A: Each lot contains 50 pieces of PTFE gaskets, making this set well-suited for both small-batch knife builds and higher-volume commercial manufacturing applications.
