PPSU Tube — IDs, ODs, Wall Thicknesses & Lengths
PPSU tube is hollow cylindrical stock produced from polyphenylsulfone (PPSU), offering the superior impact resistance, hydrolytic stability, and thermal capability of PPSU in a pre-formed tubular shape. PPSU tube is used in medical, aerospace, and plumbing applications where hollow components must maintain mechanical and dimensional integrity through sterilization cycles, hot-water service, and demanding cleaning processes.

Typical Applications
PPSU tube stock is turned into hollow components for demanding service environments:
- Medical sterilization trays and instrument tubes — survives repeated autoclave cycles without degradation
- Plumbing and hot-water fitting sleeves — hydrolytic stability for sustained hot-water service
- Aerospace fluid-system tubes and conduits — toughness and temperature capability for aviation environments
- Industrial pump sleeves and bearing tubes — impact resistance and thermal stability in process equipment
- Food processing conduit and guide tubes — cleanability and chemical resistance in hygienic systems
- Custom hollow medical and lab components — starting from tube stock reduces machining time vs. solid rod
Machining PPSU Tube
PPSU tube machines cleanly on a lathe with carbide tooling. The pre-formed bore allows concentrating machining effort on OD finishing and length cuts. Use moderate feeds and speeds to avoid heat buildup on the machined surface. Thin-wall sections benefit from plug mandrel support to maintain concentricity during OD turning. Parting and facing produce smooth, burr-free ends without special tooling.
