PTFE CNC machining & expanded PTFE sealing
From a drawing to a finished component, Liantuo supports engineering and procurement teams with precision PTFE machining and practical expanded PTFE sealing options.
Liantuo PTFE manufactures precision PTFE components and expanded PTFE sealing materials for industrial applications. We work from drawings, CAD files, samples, and clearly defined performance requirements.
Whether you are replacing an existing component or specifying a new one, we help turn the requirement into a practical part, material, and delivery plan for teams worldwide.
High-performance expanded PTFE (ePTFE) sealing materials
Conformable ePTFE sheet for flat-face flanges and difficult sealing surfaces. Send your service conditions for a practical material recommendation.
Flexible ePTFE joint sealant tape for irregular, large, or non-standard flange faces where a made-to-length seal is helpful.
Custom-cut ePTFE gaskets for repeatable sealing assemblies. Share a drawing or sample to discuss profile, dimensions, and application needs.
PTFE components and ePTFE sealing materials for environments where fit, media, and service conditions matter.
Sealing and machined parts for corrosion-resistant handling equipment, pipework, pumps, and valves.
Material options for equipment designers who need cleanable, application-appropriate polymer components.
Custom PTFE parts and sealing formats for harsh media, thermal cycling, and maintenance-sensitive equipment.
Drawings-based PTFE machining for fixtures, insulation parts, wear components, and bespoke assemblies.
Custom parts machined to your exact specifications
Send us your drawings — we machine it for you. Tolerances up to ±0.01mm.
Expert knowledge on PTFE materials, sealing technology, and industrial applications
Standard PTFE (Polytetrafluoroethylene) is known for its chemical resistance, but it suffers from cold flow and creep under load. Expanded PTFE solves these problems with a microporous, fibrillated structure that offers superior conformability, sealability, and zero cold flow.

PTFE sheet gasket, pre-cut gasket, or joint sealant tape? The right choice depends on your flange type, pressure rating, temperature, and whether the flange is standard or custom geometry. Learn the key decision criteria that help engineers select the right ePTFE sealing product every time.

Custom CNC machining for PTFE and engineering plastics. Tolerances to ±0.01mm, no MOQ, 5-15 day lead time. Order custom parts from your PDF, CAD, or sketch drawings.
Read More →Clear technical communication from the first enquiry through delivery.
Share PDF, CAD, STEP, STP, a sketch, or a sample. We review the request around geometry, material, and practical production requirements.
Discuss virgin, filled, expanded, or machined PTFE options against your media, temperature, loading, and regulatory requirements.
We prepare products for international shipment and can align packaging and documentation with your receiving requirements.
Start with the information you have; we can help structure the remaining technical details.
Send a drawing, CAD file, sketch, or sample together with material preference, dimensions, tolerance, quantity, end use, and target delivery location. If details are still being defined, describe the operating conditions and we can help clarify the request.
The right format depends on flange geometry, service conditions, installation method, and whether a standard or custom profile is required. Sheet is commonly cut to size, pre-cut gaskets suit repeatable profiles, and joint sealant tape is useful for irregular or large flange faces.
Yes. Share the media, temperature, pressure, mechanical loads, dimensions, and application. We can discuss practical options for virgin, filled, machined, or expanded PTFE materials before production.
Tell us what you need and include as much technical detail as you have.
For the most useful response, include your drawing or dimensions, quantity, material preference, application, and delivery destination. We will review the request and follow up with the next practical step.
