Description
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
- 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}.
