Series 366, 3/8" / DN10 Stainless Steel

  • Flat-Face design    
  • Stainless steel design
  • One-hand operated

    LEH Series 366 is a Flat-Face quick-connect coupling dimensionally in accordance to ISO 16028 Standard for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. The stainless steel design makes it extra sturdy to fit applications in extreme environments. Series 366 couplings require only one hand for operation, making connection and disconnection fast and easy. Dust caps are available as accessories for both the coupling and nipple to prevent dust and debris from entering the system. Series 366 couplings also feature manual security locking as added protection against involuntary disconnection.

    he couplings and nipples are also available in three other sizes; 1/4" / DN 6.3 (Series 266), 1/2" / DN 12.5 (Series 566), 3/4" / DN 19 (Series 766). For a steel version see Series 365. Nipples with pressure eliminator available under Series 364.
