MODEL 1212 HEAVY DUTY FLEXIBLE COUPLING The Lede Model 1212 heavy duty flexible coupling is designed for use in a variety of general piping applications of moderate or high pressure services. Working pressure is usually dictated by the wall thickness and rating of the pipe being used. The Model 1212 couplings feature flexibility that can deal with misalignment, distorƟon, thermal stress, vibration and noise and also resist seismic tremors. With the use of Model 1212 couplings you can even design a curved layout. See Typical Applications – Flexible Couplings on page 44. Sizes available: 32mm-300mm / 11/4’’~12’’ Working Pressure: Up to 35 bar / 500 psi
