Catalog MRO-6WAFeatures & Part NumbersFittings & TubingPolyurethane TubingFitting Recommendations• Thermoplastic fittings• Brass fittingsAdvantagesPolyurethane tubing is a high quality,precision‐made tubing used in a wide rangeof demanding and critical applications.Polyether based, polyurethane tubing occupiesa unique position among polymers,sharing the best properties of bothrubber and plastic. Urethane exhibits theelongation and recovery characteristicsof rubber and the chemical resistanceassociated with plastics. The tubing istough, strong, kink-resistant and abrasionresistant, yet it’s flexible and easy toassemble onto designated fittings.• Tough• Flexible• Broad Temperature Range• Eight Colors• Abrasion Resistant• Chemical ResistantApplications & ApprovalsPolyurethane tubing is used for a widevariety of applications. Typical usageincludes air tools, robotics, pneumaticlogic and actuation systems, analyticalinstrumentation, vacuum equipment,pressure measurement apparatus,semi‐conductor equipment manufacturersand a variety of medical and laboratoryapplications.Temperature RangeSuggested operating temperatures,depending upon conditions are 0°F to200°F (‐18°C to 93°C).NomenclatureOrder by tubing part number and name.Example:U ‐ 2 1 ‐ BLK ‐ 0250Polyurethane1/8" (2/16) Tube O.D.1/6" (1/16) Tube I.D.Color - BlackReel Length in FeetU Polyether Base TubingNom.
