Series 264, DN6.3 Pressure Eliminator
- Flat-Face design
- Connection under pressure
- One-hand operated
CEJN Series 264 is a Flat-Face quick-connect nipple with a built-in pressure eliminator. The nipple is according to and exceeds the demands in the ISO 16028 Standard for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. The pressure eliminator allows for connection with residual/trapped pressure on the nipple side. The nipple Series 264 connects with couplings in Series 265, Series 266 and Series 262.
The pressure eliminator nipples are also available in four other sizes; DN 10 (Series 364), DN 12.5 (Series 564), DN 16 (Series 664), DN 19 (Series 764). For steel couplings in accordance with ISO 16028 see Series 265. Stainless steel versions of the standard are available in Series 266. Series 262 feature an interchangeable steel coupling designed for lower pressures.
