By mechanical-bonding a virgin Polytetrafluoroethylene (PTFE\/F4) or FEP\/F46 interior liner to a heavy-duty EPDM or NBR rubber bellows shell, these advanced flexible connectors provide absolute chemical inertness combined with exceptional multi-axis thermal expansion and vibration compensation.<\/p>\n<h3 style=\"font-size: 16px;
