The straight-tube dimensions alone do not establish usable reach, pull force or fatigue life. ### Pressure and temperature conditions Pressure and temperature ratings are listed separately; send your operating point for a combined-condition check. **Working pressure** is the design rating; burst pressure is a test value. Confirm the model-specific limits, test conditions and complete fitting assembly before use. ### Related selection information [PU straight tubing →]() . ### Recoil tubing for a moving air connection Specify the tube ID and OD separately from coil dimensions and working reach. Compare the complete end connections and movement requirements; usable reach, pull force and fatigue life depend on the full assembly.

Pressure and temperature ratings are listed separately; **working pressure** is the design rating and burst pressure is a test value. Media compatibility depends on concentration, temperature and service conditions. Lengths listed below are tube supply / coil lengths, not recoil extension lengths. Spiral diameter, number of turns, usable extension and fittings are confirmed on request.

Prepare circuit, dimension and pressure details.]() QUESTIONS ## Product FAQ How do I specify coiled polyurethane tubing working reach? Provide tube ID and OD, coil diameter, turn count, straight ends, fitting details and the required usable reach. Supply length and coil length are not the same as extension length. Confirm the coil arrangement and service conditions for the selected model. Which coil dimensions need confirmation for PU recoil tubing? Provide coil outside diameter, number of turns, straight end lengths, connection details and intended travel. Confirm the complete assembly before ordering. Does recoil form establish a movement-cycle rating? No movement-cycle result is supplied by the recoil shape alone. Discuss the motion, bend space, loading and required evaluation for your equipment. ## Let’s Discuss Your Tubing Requirements. Looking for a standard size or a custom specification?
