The Series 320 is a universal, pneumatic coupling suitable for a variety of applications. It features the original high-flow valve design that all other CEJN pneumatic couplings are based upon. Their popularity has made Series 320 a European standard. The series is easy-to-handle, one-hand operated and offers long service life. Male threads on the couplings and nipples feature pre-applied thread sealant.

Series 320 is also available in Vented Safety, Lightweight, Soft-Line and Multi-Link versions. Please refer to the CEJN Fluid range for specialized versions of Series 320 with two-way shutoff (Series 324) and stainless steel construction (Series 326).
