Hydraulic Products, X64 Range - ISO 16028 Flat-Face Pressure Eliminator Nipples

Series 364, DN10 Pressure Eliminator

  • Flat-Face design
  • Connection under pressure
  • One-hand operation


CEJN Series 364 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 364 connects with couplings in Series 365, Series 366 and Series 362.


The pressure eliminator nipples are also available in four other sizes; DN 6.3 (Series 264), DN 12.5 (Series 564), DN 16 (Series 664), DN 19 (Series 764). For steel couplings in accordance with ISO 16028 see Series 365. Stainless steel versions of the standard are available in Series 366. Series 362 features an interchangeable steel coupling designed for lower pressures.
