Series 064, 1" / DN25 Pressure Eliminator

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

    LEH Series 064 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 064 connects with couplings in Series 065.

    T
    he pressure eliminator nipples are also available in five smaller sizes; 1/4 " / DN 6.3 (Series 264), 3/8" / DN 10 (Series 364), 1/2" / DN 12.5 (Series 564), 5/8" / DN 16 (Series 664) and DN19 (764).
