National Fluoromers is a specialized manufacturer, supplier, and exporter of PTFE rod seals, offering advanced sealing solutions for reciprocating rods in hydraulic and pneumatic cylinders. These seals are ideal for environments involving high pressure, aggressive chemicals, and elevated temperatures.

Crafted from high-grade virgin or filled PTFE, our rod seals ensure leak-proof performance, minimal friction, and exceptional resistance to wear—even in the most demanding industrial conditions.

what is a PTFE rod seal?

A PTFE rod seal is a dynamic sealing element designed to seal the rod shaft of a hydraulic or pneumatic cylinder. It prevents fluid leakage from the cylinder and blocks contaminants from entering the system. The inherent properties of PTFE—such as low friction, excellent thermal stability, and chemical inertness—make these seals ideal for long-life applications across diverse industries.

Rod seals are critical in maintaining the system’s pressure balance, minimizing downtime, and enhancing machine reliability.
