Material selection
Choose virgin PTFE for purity and chemical resistance; select glass-, carbon- or mineral-filled PTFE when reduced creep or wear is needed.
DRAWING-BASED CUSTOM PARTS
Custom Virgin PTFE Washers
Low-friction virgin PTFE washers for chemical, thermal and electrical environments beyond the range of ordinary elastomers.
Custom-cut or machined virgin PTFE washers for chemical resistance, low friction and stable performance across a very broad temperature range.
Engineered Custom Virgin PTFE Washers
Virgin PTFE washers isolate hardware and distribute clamp load where aggressive chemicals, elevated temperature or low friction would quickly degrade standard plastics or rubber. They can be die cut from thin sheet or machined when thicker sections and tight geometry are required.
Material approach
PTFE has exceptional chemical resistance, very low friction and a broad service temperature range.
Key features
- Virgin fluoropolymer purity
- chemical resistance
- low coefficient of friction
- wide temperature range
- custom ID
- OD and shape.

Engineering Guide
Practical points to include when selecting foam and preparing a drawing for review.
Geometry and thickness
Use broad bearing areas and controlled torque; avoid sharp loaded edges that can encourage cold flow.
Assembly performance
PTFE is highly chemical resistant but mechanically softer than metal. Design clamp loads and supports for long-term dimensional stability.
Production route
Account for PTFE creep under sustained clamp load; use suitable flange design, backing support or retorque procedures where required.

Frequently Asked Questions
What does virgin PTFE mean?
It means the washer is made from unfilled, primary PTFE resin rather than recycled or compounded material.
Can PTFE washers handle acids and solvents?
PTFE resists a very wide range of chemicals; confirm compatibility for the exact chemical, concentration and temperature.
Will a PTFE washer creep under bolt load?
PTFE can cold flow under sustained pressure, so joint design, bearing area and torque management are important.
Can PTFE washers be made in non-round shapes?
Yes. Die cutting, waterjet cutting and machining can create slots, tabs and custom profiles.
What should a drawing include for custom virgin ptfe washers?
Include chemical media, temperature, fastener load, bearing area, creep allowance and required geometry.
Can custom virgin ptfe washers be supplied for production assembly?
Yes. Account for PTFE creep under sustained clamp load; use suitable flange design, backing support or retorque procedures where required. Delivery format, liner configuration and packaging are specified for the assembly workflow.
How is the right custom virgin ptfe washers construction selected?
Choose virgin PTFE for purity and chemical resistance; select glass-, carbon- or mineral-filled PTFE when reduced creep or wear is needed. The drawing and operating conditions establish the final construction.
