SMC Series Subminiature Couplings

The SMC subminiature fittings are CPC™'s smallest couplings. These twist-to-connect couplings provide a reliable and more secure alternative to luer-type connections, which allow the tubing to rotate when it is connected. This functionality prevents both kinked tubing and accidental disconnection during use. The fittings are available in three sizes with either straight thru or shutoff flow. Note: Bodies and inserts are separately sold unless marked as "Coupling Set." The tubing ID determines the size of the Hose barb fittings. ABS coupling bodies are disposable.

  • ABS, acetal & polypropylene main components
  • Acetal locking sleeves & valves
  • 316 SS valve spring
  • Buna-N O-rings on ABS & acetal connectors
  • EPDM O-rings on polypropylene connectors
  • Free coupling rotation eliminates kinked tubing
  • Pressure rating: vacuum to 100 psi, 6.9 bar except 65246 & 65247 (120 psi, 8.3 bar)
  • Acetal temperature range: -40°F to 180°F (-40°C to 82°C)
  • Polypropylene temperature range: 32°F to 180°F (0°C to 82°C)
  • ABS temperature range: -40°F to 160°F (-40°C to 71°C)
