Fluid Products, Full-Flow Brass Couplings & Nipples

DN38 (Series 851)

  • Valveless design
  • Unrestricted flow
  • Tarnish-resistant finish

CEJN Series 701, 851, and 921 brass couplings feature an economical valveless design that permits unrestricted, high flow and accommodates high viscosity fluids. The straightforward design reduces pressure drop. The couplings offer long service life in low-pressure applications, such as fluid transfer, mold coolant/heating, chemical processing, and vacuum service. Optional color-coded rings and a safety-locking device are available for added safety protection.

CEJN full-flow couplings are also available in stainless steel. See Series 702, 852, & 922.
