High wear Ekonol PTFE tube is a precision-machined, filled PTFE material developed for seals, bushings, and wear components that operate under high load and minimal lubrication. As a dependable 10% Ekonol PTFE tube supplier, we supply both raw extruded lengths and CNC-finished parts in tight tolerances. The product is often called aromatic polyester PTFE tubing because Ekonol is an aromatic polyester resin that reinforces the PTFE matrix. Engineers choose the 10% Ekonol PTFE tube for compressor seal duty where heat, pressure, and side loading can cause standard PTFE to cold-flow or wear rapidly. Our Ekonol filled PTFE tube low creep grade is formulated to hold dimensions over long service intervals, making it ideal for reciprocating compressors, hydraulic cylinders, and rotary unions. The Ekonol filler increases load-bearing capacity and reduces stick-slip, which is critical in sealing systems that cycle thousands of times per day.
High Wear Ekonol PTFE Tube uses a 10% Ekonol filler by weight in a virgin PTFE base. The filler increases hardness, lowers deformation under load, and reduces wear against steel and chrome surfaces without sacrificing PTFE's natural lubricity or resistance to acids, solvents, and oxidizing chemicals. This grade is typically brown or tan in color and is produced with both isostatic molding and paste extrusion techniques to support small to large diameter requirements. The material is particularly valuable in reciprocating compressors, where the tube must survive rapid pressure swings and side load without extruding into the clearance gap. The low-creep behavior also helps maintain a consistent seal interface, minimizing leakage and extending packing life. Compared with bronze-filled or carbon-filled PTFE, high wear Ekonol PTFE tube is softer against mating surfaces and generates less wear on stainless steel shafts and hardened liners, which reduces maintenance downtime in gas compression, refrigeration, and hydraulic machinery.

High Wear Ekonol PTFE Tube is available in both sintered and stress-relieved conditions to minimize residual stress and improve machinability. Every production lot is checked for density, hardness, tensile strength, and dimensional accuracy. Non-destructive testing and lot traceability are available on request. The material is RoHS and REACH compliant and can be supplied with material certification documents. The product can be bonded or press-fitted into metal retainers, and it can be machined to complex profiles for demanding sealing applications.
