Low pressure, clean break coupling

The CT Series clean break couplings are Walther Precision's latest design in "push to connect" couplings for use in low pressure applications, up to 928psi. Using AISI 304 stainless steel in conjunction with AISI 316 hose fittings, the affordable CT Series is suitable for applications which demand minimal leakage during connection or disconnection while offering fool-proof handling and high flow rate. Finding a coupling system to fit your requirements is made possible with the availability of small bore sizes of 5mm, 7mm, 9mm and 12mm and large bore size of 19mm. Within each size, a choice of NPT, BSPP, Metric and Hose-barb connections are available.

Of special note, the CT-019 (19mm bore) is available with optional ring-grips to aid in connection/disconnection as well as a "Break-away" feature.


  • Clean break/squirt free during connection/disconnection with minimal spillage
  • Automatic locking with simple "push to connect" operation
  • Compatible with both non-lubricating and lubricating fluids
  • Easy cleanable surfaces
  • Can be connected at residual pressures (see technical data)
  • High flow rate
  • Available in an ATEX conforming version
  • "Break-away" feature available in 19mm nom. bore version
