Product Details
The Series 320 nipple, featuring a 1/4" male NPT (European interchange), is designed with the original high-flow valve that forms the basis for all other CEJN pneumatic couplings. This series has gained widespread popularity, establishing itself as a European standard. It is designed for easy handling and one-hand operation, ensuring a long service life. Male threads on both the couplings and nipples are equipped with pre-applied thread sealant. Notably, the Series 320 vented safety version offers a two-stage disconnection to vent the coupling, thereby reducing the risk of sudden component separation which could lead to operator injury. The full automatic operation further enhances ease of use. Additionally, the vented safety version meets compliance with ISO standard 4414 and EN 983, while offering extremely high flow capacity, strong durability, and ease of connection.
