Polyurethane tubing is usually the best choice for applications requiring extensive flexing, a small bend radius or where kinking can be a problem. Nycoil uses ether base (polytetra-methylene glycol ether) raw material because of its hydrolytic resistance (will not break down or be affected in any way by moisture). Being a natuͭrally rubbery compound, it requires no plasticizers that can leach out over time. This compound also offers superior resistance to grease, oils, fuels and abrasion, making it suitable for a wide variety of applications.

Due to its lower burst and temperature characteristics, the uses for Polyurethane is best recommended on applications where the flow rate is not critical and temperature elevation of the tubing is not a factor. When using Polyurethane tubing in most pneumatic systems, one size larger tube is often required in order to meet the necessary flow criteria.

As a result, applications should be limited to areas of consistent low temperatures and where high and continued flexibility is essential. Atypical example of this would be a "pick and place" operation.

Since Nycoil "РЫу-Matic" Push-To-Connect Fittings have the highest gripping "force" as compared to other brands, it is assured that our tubing will always work with our fittings. However, when using Push-To-Connect Fittings from other manufacturers with any brand of Polyurethane tubing, testing for retention reliability is strongly recommended. Further, we recommend using only Polyurethane tubing made from 95A Durometer hardness compound with Rjsh-To-Connect Fittings. In addition, compression type fittings should never be used with Polyurethane tubing of any hardness.

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. Produced from ether base (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. 95A Durometer Polyurethane Tubing can be used with most brands of Push-To-Connect or Hose Barb Fittings
