Polyurethane hose, Hose Ø 12x1.5 mm, silver, Roll of 25 m - Riegler 113690

Polyurethane hose (PUR), Temperature -20 °C to 60 °C, Hose Ø 12x1.5 mm, PN at 23 °C max. 8 bar, silver, Roll of 25 m Polyurethane hoses are renowned for their extreme flexibility and correspondingly narrow bending radius across a wide temperature range. They are more flexible even than LD-PE hoses and exhibit good abrasion resistance, very good low-temperature flexibility, only minimal permanent deformation when subjected to long-term stresses as well as good resistance to the majority of oils, greases, aliphatic hydrocarbons and oxygen. Main applications: - Pneumatic and hydraulic (miniature hydraulics) lines - Mechanical engineering - Engine construction - Instrumentation and control - Ideal for use with unions, as externally calibrated

About PA-/ PUR-/ PE-hoses

Plastic tubing links valves, cylinders and manifolds in a compressed air installation. The right material follows from temperature, bend radius and permissible pressure. This group holds 222 items in polyamide, polyurethane and polyethylene, supplied from the reel.

What matters when choosing

• Start with the tube material. Polyamide PA 12 keeps its impact and notched impact strength down to -60 °C, resists corrosion and stays dimensionally stable thanks to low water absorption, polyurethane is considerably more flexible and more abrasion resistant, polyethylene covers simple lines.
• Inner and outer diameter belong together and determine flow and the matching push-in fitting. The range offers pairings such as 3x0.75, 4x1, 6x4 and 8x6 mm.
• Maximum operating pressure is stated at 23 °C and depends on wall thickness. In PA 12 that means 27 bar at 6x4 and 19 bar at 8x6, in PUR 13 bar at 3x0.75 and 16 bar at 4x1.
• Check the temperature range against the installation point. PA 12 is documented from -60 °C to 100 °C, PUR from -20 °C to 60 °C.
• Choose colour and reel length to suit the installation. Natural, blue, black, yellow and red are among the options, which makes it easier to mark control and working circuits.

Typical applications

• Connecting valve manifolds to cylinders and grippers
• Control air lines inside machines and control cabinets
• Moving lines in cable carriers, where tight bend radii and abrasion matter
• Vacuum and handling technology at suction cups
• Retrofitting compressed air distribution at assembly benches

Countries of origin documented for the 222 items are Germany, Italy and Taiwan. Tube material, wall thickness, reel length and the permissible pressure at 23 °C are listed per item in the data table.
