Maximum abrasion resistance, less wear and tear
Inline hose with 5.5 times service life
Masterflex AG has developed a unique process for producing hoses which are seamlessly smooth on the inside, thus achieving hose qualities with a previously unknown smoothness. “The Master polyurethane inline hoses offer the unique combination of maximum abrasion resistance with enormous wall thicknesses, low weight and amazing bending radii”, explains Detlef Herzog, Managing Director of Masterflex AG. “And so they are a real competitor to the heavy rubber hose.”
The patented process combines the advantages of the extruded hose with the special characteristics of the materials with which the hose’s smoothness is achieved. During manufacture, the hose is furnished with different hi-tech components. In the case of conventional hoses, the construction-induced weld seam is a major weak spot because the corrosion of the material to be conveyed takes place on the edges of the seam. By cleverly combining the materials, the hose is suitable for all manner of fields of application, specially for the transport of abrasive and corrosive media. Test results have shown that under comparable conditions the inline hose will last at least 5.5 times longer than the best rubber hose tested in the company’s laboratory using the procedure according to DIN 53516.

Although 95A Durometer is the hardest compound used for Polyurethane tubing, it is still more flexible and has a smaller bend radius (without kinking) than most other plastic tubing. Production from an ether-based (polytetra-methylene glycol ether) raw material assures resistance to moisture, fungus, abrasion and a broad range of chemicals making it a popular choice for many applications. A wide selection of colors makes it adaptable to the functional and aesthetic requirements of most pneumatic circuits and equipment.
