Products

High performance Ekonol PTFE tube is engineered for demanding pump seal and bearing applications where standard unfilled PTFE does not provide sufficient wear life or dimensional stability. As a leading Ekonol filled PTFE tube manufacturer, we supply precision-machined tubing that combines the low friction and broad chemical resistance of PTFE with the high abrasion resistance of aromatic polyester filler. The 15% Ekonol PTFE tube for pump seal delivers consistent face contact and reduced leakage in rotary equipment. For applications with high sliding velocities, our aromatic polyester filled PTFE tubing high wear grade is formulated to minimize material loss and extend maintenance intervals. Compared to virgin PTFE, this filled grade also shows a major reduction in cold flow under load, which is why design engineers select Ekonol PTFE tube low creep for critical bushing and seal ring installations. Each production lot is blended, compression molded, sintered, and machined in-house to ensure uniform dispersion of the Ekonol filler and repeatable mechanical properties.

High Performance Ekonol PTFE Tube is available in a wide range of standard and custom dimensions for pump seals, wear rings, valve seats, and compressor components. The material is produced from virgin PTFE resin with a precisely controlled 15% aromatic polyester filler loading. Standard dimensional options and key features include:

• Inside diameter: 2 mm to 200 mm (0.079 in to 7.874 in)
• Wall thickness: 1 mm to 50 mm (0.039 in to 1.969 in)
• Length: 100 mm to 1000 mm (3.94 in to 39.37 in); longer sections available on request
• ID/OD tolerance: ±0.05 mm for machined surfaces; ±0.10 mm for as-molded stock
• Filler content: 15% Ekonol (other filler percentages available for OEM programs)
• Color: light tan to brown with uniform filler distribution
• Standards: ASTM D1710, ASTM D4894, FDA-compliant options for food contact
• Custom lengths, chamfers, and radial grooves can be machined to print
• Non-standard inside diameters and thick-wall sections are produced on a per-order basis with short lead times
• Each lot is fully traceable to raw material certificates and is inspected for dimensional accuracy, filler dispersion, and surface finish before shipping
