Made from virgin or filled PTFE, these balls offer unmatched resistance to chemicals, extreme temperatures, and friction — making them ideal for precision components that require reliability without contamination.
A PTFE ball is a solid, spherically shaped component machined from polytetrafluoroethylene. It is commonly used in fluid handling systems where chemical compatibility, zero moisture absorption, and thermal stability are essential. The non-adhesive and self-lubricating nature of PTFE allows the ball to rotate or seal without sticking, even after extended use.
PTFE balls are ideal for systems where hygiene, precision, and chemical purity matter.
