TL TYPE

Medium pressure, Valveless Type
  • Valveless structure reduces pressure loss and allows high flow rates.
  • This is suitable for piping of viscous fluid, steam or powder.
  • Various packing materials enables a wide variety of applications.
  • SUS316 is available.
  • Male thread, female thread and hose nipple can be connected in one size.
  • Other packing material are available; please consult with us.→ Contact
Medium pressure, Valveless TypeMedium pressure, Valveless Type
  • When connected, the fluid is sealed completely by O-ring.
  • Fluid can flow from both socket and plug.

Caution:

  • Do not connect or disconnect couplings under pressure.
  • Fluid in pipe will be discharged on disconnection. Be careful when dangerous fluids are to be used. (Such as chemicals or hot fluids)
  • Different sizes are not interchangeable.
  • Scraps of the seal tape and dust causes fluid leakage. Be careful not to stick them to the couplings.
  • Do not impact, hit, pull or bent. Don't dismantle. It causes damage to the coupling.
