Breaking a liquid line should leave nothing dripping and nothing running out. The Nitto Kohki Compact Zero Spill Cupla is designed for spill-free disconnection and has a stainless steel body.

  • Design for spill-free disconnection, the fluid stays in the line when the coupling is broken
  • Stainless steel body on every model in the range
  • EPDM as the sealing material across the whole range
  • Compact build, which keeps the space needed at the coupling point small
  • Two sizes in the CZL model range, each available as a socket marked S and as a plug marked P, both with a male thread

Operating principle

Two-way shut-offTwo-way shut-offshut-off valve in socketshut-off valve in plugSocketPlugFlow direction: socket to plug
Both halves close on disconnection, so the line contents are retained on both sides.
  • Compact size saves space. Outer diameters of 16 mm (CZL-1SM) and 18.5 mm (CZL-2SM).
  • High flow rate for efficient cooling.
  • Easy operation, push-to-connect function.
  • Valve structure reduces air inclusion on connection and liquid spillage when disconnecting.
  • Small, high flow type for coolant piping.

Choose COMPACT ZEROSPILL CUPLA when air inclusion on connection and liquid spillage on disconnection have to be limited: it is two-way shut-off with spill reduction, while the sibling series in this group - HI CUPLA BL, NUT CUPLA, LOCK CUPLA 200, PURGE LINE CUPLA and ROTARY LINE CUPLA - are one-way shut-off. Its socket outer diameter of 16 mm (CZL-1SM) or 18.5 mm (CZL-2SM) in sizes 1/8 inch and 1/4 inch suits coolant piping in tight space. If the line runs up to 1.5 MPa {15 kgf/cm2}, one of the one-way shut-off peers is the better choice, because this series is rated 1.0 MPa {10 kgf/cm2}.
