PTFE Bushings — Material Specifications, Engineering Data & OEM Supply
HEMSUN ENGG. INDUSTRIES manufactures PTFE Bushings in Dahegam, Gandhinagar, Gujarat, India for high-performance industrial sealing, chemical processing, and valve OEM applications. Engineered from 100% virgin and custom-filled PTFE fluoropolymer, featuring chemical inertness (pH 0–14), wide operating temperature (-200°C to +260°C), and precision CMM-inspected tolerances for domestic and export supply.
Where PTFE Bushings is used
Plain bearing carrying radial load without grease, relying on the polymer’s low friction where oil lubrication is unwanted or impossible.
PTFE suits dry plain bearings because it runs against steel without seizing, removing the grease point altogether.

Manufacturing process
Production of PTFE Bushings combines cold isostatic/uniaxial compaction of PTFE fluoropolymer powder with multi-stage thermal free-sintering. Compaction loads are held under precise electronic dwell timing to bleed out microscopic air pockets. Sintered blanks are then transferred to climate-controlled CNC turning and milling centers to machine critical drawing features.
Material selection notes
Manufactured from PTFE fluoropolymer, this component combines high tensile strength (20–35 MPa) with excellent chemical and weathering resistance. The material maintains flexibility at low temperatures while providing stable compressive support under high system pressures.
How to specify your order
For engineering consultation on PTFE Bushings, 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
Inspection protocols for PTFE Bushings encompass dimensional coordinate verification, density testing, sphericity profilometry on balls, and visual surface inspection under optical magnification. Full mill test certificates (MTR) accompany all shipments.
Ordering and export documentation
Domestic PTFE Bushings 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. Material certificates and dimensional reports attached for qualified pharmaceutical and OEM shipments Contact info@hemsun.com or sales@hemsun.com with your bushes specification.
Export packing and lead time
International distribution of PTFE Bushings is supported with multi-currency commercial terms, export shipping documentation, and protective multi-layer packaging to ensure components arrive in pristine condition worldwide.
Storage and handling
Care and handling for PTFE Bushings: Protect machined sealing edges against impact during transit and staging. Do not exceed recommended compressive stress limits during mechanical flange tightening.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Bore, wall and concentricity are verified on CMM against drawing nominals, with sintered density checked per ASTM D792 to confirm full compaction. A mill test certificate ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
