PTFE Rods

PTFE rods are solid cylindrical fluoropolymer stock supplied for machining into seals, valve seats, insulators, bushes and other precision components. Virgin and filled grades offer different combinations of chemical resistance, friction, wear, dimensional behaviour and mechanical support for industrial fabrication.

Questions about ptfe rods

What should I send to identify ptfe rods?

Send rod diameter, length, virgin or filled grade, quantity, machining allowance or tolerance. State the filler type and grade explicitly because rod colour alone cannot confirm its composition or suitability. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select ptfe rods?

Choose virgin or filled material from chemical exposure, bearing load, wear, creep, electrical needs and machining stability. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
