PTFE Bellows — Flexible Expansion Elements for Aggressive Media

Available in convoluted or turned designs, PTFE bellows combine high flexibility with excellent chemical resistance, absorbing axial displacement, vibration and misalignment while isolating aggressive media in pumps, piping and mechanical seals.

Key features

1.Universal chemical resistance — inert to virtually all acids, alkalis and solvents, even at elevated temperatures.

2.Built-in flexibility — convoluted design absorbs axial movement, vibration and angular misalignment without additional joints.

3.Wide thermal range — continuous service from -60°C to +230°C.

4.Full vacuum to pressure capability — resists collapse and burst across the full operating envelope.

5.Non-stick, zero-contamination flow path — smooth PTFE surface prevents media buildup and product carryover.
