Series 764, DN19 Pressure Eliminator
- Flat-Face design
- Connection under pressure
- One-hand operated
CEJN Series 764 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 764 connects with couplings in Series 765 and Series 766.
The pressure eliminator nipples are also available in four smaller sizes; DN 6.3 (Series 264), DN 10 (Series 364), DN 12.5 (Series 564) and DN 16 (Series 664). For steel couplings in accordance with ISO 16028 see Series 765. Stainless steel versions of the standard are available in Series 766.
