PTFE Washer — Material Specifications, Engineering Data & OEM Supply
PTFE Washer is manufactured in Gujarat by HEMSUN ENGG. INDUSTRIES, providing tight dimensional accuracy and long service life in thrust washers and disc spacers. Features premium PTFE fluoropolymer compounding, void-free sintering, and precision CMM inspection.
Where PTFE Washer is used
Thrust and anti-friction washer taking axial load between rotating and static faces, and insulating dissimilar metals from contact.
PTFE suits thrust washers because it carries axial load at low friction while electrically isolating the faces either side.
A washer is specified to carry axial load and keep two faces apart; where the interface must actually retain pressure or exclude media, a seal is specified instead.

Manufacturing process
Our dedicated manufacturing cells produce PTFE Washer from premium PTFE fluoropolymer powder stock. After uniaxial preforming in precision tooling, components undergo computer-monitored sintering cycles and diamond-tooled CNC profiling to hold exact drawing dimensions.
Material selection notes
The PTFE fluoropolymer material utilized in PTFE Washer exhibits exceptional dielectric insulation (up to 80 kV/mm) and zero moisture absorption (<0.01%). It withstands thermal cycling between cryogenic temperatures and +260°C without embrittlement or dimensional degradation in demanding industrial environments.
How to specify your order
For engineering consultation on PTFE Washer, send your component specifications, media compatibility parameters, and production batch sizes. We provide material datasheets, sample trial options, and detailed technical quotes within one business day.
Quality checks and inspection
Each shipment of PTFE Washer is verified through comprehensive QA benchmarks: CMM dimensional layout, density gradient analysis, high-voltage insulation breakdown testing, and certified inspection reports.
Ordering and export documentation
Domestic PTFE Washer orders ship with GST invoice and e-way bill where applicable. Export orders include commercial invoice, packing list, and certificate of origin from our IEC-registered works. Recurring supply schedules supported with fixed drawing revision and lot numbering for plant stores Contact info@hemsun.com or sales@hemsun.com with your washers specification.
Export packing and lead time
We provide full export support for PTFE Washer orders worldwide. International documentation includes Certificate of Origin, packing lists, material safety data sheets, and custom export crating designed to withstand long-distance maritime transit.
Storage and handling
Storage, installation, and operating recommendations for PTFE Washer: Store in clean, temperature-controlled dry storage away from direct UV exposure and particulate contamination. When installing in valve bodies or pump housings, ensure mating surfaces are free of sharp burrs to avoid seal lip damage.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Sealing faces are inspected for flatness and finish, thickness verified on calibrated gauges, and sintered density checked per ASTM D792. A mill test certificate ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
