Double-Shut Off Hydraulic Couplings - Zero-Leak Quick-Disconnect Fittings for Heavy-Duty Construction Machinery

CB-SPL-1FG and CB-SPM-1FG hydraulic double shut-off couplings are engineered for reliable fluid transfer in demanding construction and hydraulic systems. Designed to prevent fluid leakage during line connection/disconnection, these couplings ensure minimal spillage during equipment operation, maintenance, or component replacement, reducing environmental risks and operational downtime.

Standard Materials

• Brass, zinc-plated steel, stainless steel
• Seals: NBR, Viton, EPDM

Features

1. Poppet valves available to prevent uncoupled leakage . Poppet valves open automatically when coupled within rated working pressure to keep the flow expeditely.
2. Critical parts are hardened for durability.
3. Compatible with PARKER 60 Series, FASTER HNV Series AEROQUIP FD45 Series and HANSEN HK Series.
