Hydraulic Products, ISO B Steel Couplings & Nipples

Series 775, DN25

  • ISO B Standard
  • Sturdy design
  • Working pressure up to 2610 PSI (180 bar)

CEJN Series 775 features quick-connect couplings and nipples are manufactured according to ISO Standard 7241-1 B. The solid design makes them particularly suitable for strenuous applications in the iron, steel, oil, food and automobile industry.

The couplings and nipples are also available in four smaller sizes; DN 6.3 (Series 375), DN 10 (Series 475), DN 12.5 (Series 575), DN 20 (Series 675). For a stainless steel version see Series 776.
