When to Buy ePTFE Sheet Stock vs Custom-Cut ePTFE Gaskets
Buy ePTFE sheet when you need 1–10 mm cutting stock up to 1520×1520 mm. Order custom-cut ePTFE gaskets when you have a drawing or sample and want finished shapes with no mold cost.
What Liantuo ePTFE sheet stock is
expanded PTFE sheet for flat-face cutting stock is 100% ePTFE flat sealing stock. Liantuo lists it for cutting full-face or other flat shapes, in sheets up to 1520×1520 mm.
This page is only the stock-versus-cut decision. For a broader seal overview, see how to choose a PTFE seal (generic) and the PTFE gasket selection overview. Those existing articles stay in place; this URL does not replace them.
What a Liantuo cut gasket is
A custom-cut expanded PTFE gaskets from your drawing is finished from ePTFE sheet to a drawing, DXF, or physical sample. Liantuo cuts by water jet or knife. There is no mold cost.
Shapes include round, oval, rectangular, and irregular forms, as stated on the gasket product page. Temperature and pressure are confirmed with the application — this page does not list separate ratings.
Size and thickness you can start from at Liantuo
The sheet product page lists thickness 1–10 mm. Custom thickness or sheet size is available on request. MOQ is confirmed with each quote.
Finished gaskets are cut to the drawing or sample — “any size” as stated on that product page. Do not read that as a published diameter catalog on this guide.
When to keep Liantuo sheet in the shop
Keep sheet on hand when the plant store or gasket shop cuts on demand: spare stock for flat, full-face work and many identical flat pieces. That matches the sheet page’s flange MRO framing.
When to order finished Liantuo parts
Order a cut gasket when a drawing or sample already exists and you need repeatable shapes — including OEM or MRO kits — ready to install. Send the print once; reorder against the same geometry.
When neither Liantuo sheet nor a cut gasket is first choice
For large, damaged, or non-standard flanges, a flat cut part is often the wrong starting point. Use form-in-place ePTFE tape for large or damaged flanges and expanded PTFE joint sealant tape. This guide does not publish a flange-diameter cutoff.

FAQ
Should I buy ePTFE sheet or a cut gasket?
Buy sheet as 1–10 mm cutting stock up to 1520×1520 mm when your shop cuts on demand. Order a custom-cut gasket when you have a drawing or sample and want a finished shape. MOQ is confirmed with each quote.
Do cut gaskets need a mold?
No. Liantuo cuts ePTFE gaskets from sheet by water jet or knife. There is no mold cost. Send a drawing, DXF, or physical sample to sales@liantuoptfe.com.
What if the flange is damaged or an odd shape?
For large, damaged, or non-standard flanges, use expanded PTFE joint sealant tape rather than a flat cut part. See the large-flange tape guide and the joint sealant tape product page.
What should I email for a quote?
For sheet: thickness, sheet size, quantity, media and temperature if known, and ship-to. For a cut gasket: drawing or sample, quantity, and service conditions if known. Samples are available.
