Unreinforced Polyurethane Tube

Polyurethane tube has outstanding characteristics when compared with tother thermoplastic materials. It has excellent flex and bend capabilities over a wide temperature range, and good resistance to abrasion. It is also resistant to many chemicals and gases and most fuels, oils and greases.

Polyurethane tube is widley used in pneumatic control systems, where it’s great flexibility and ease of handling soeeds up installation. It can be used for fuel and liquid lines. For positive fixing we recommend push on typ e fixing where practicable.

Working Pressures and Temperatures

The working pressures within the chart below are based on the short term burst pressure at 20°C using a 4 to 1 saftey factor. Maximum recommended continuous working temperature 55°C with occasional short term use to 85°C, the minimum being -50°C.

Coil Lengths and Colours

Standard coil length 30 metres, alternative coil lengths are available further information may be obtained from our Technical Sales Office.

All our range of tube sizes are available in Natural, Red, Black, Green and Yellow.
