✅ Dust Caps & Plugs Included – Protect sealing surfaces when not in use.
Applications
✅ Wet line kits
✅ Dump trailer hydraulic lines
✅ Submersible pumps
✅ Engine test stands
✅ Oil & gas field equipment
✅ Construction and agricultural machinery
Characteristics
This heavy-duty FB wing nut coupling stands up to repeated hammering during assembly and disassembly. Its integrated valve seal enables safe connection and disconnection at full pressure without seal damage. The corrosion-resistant brass body works with various hydraulic media for wide application. Flat-face valves are easy to clean, while the screw design allows pressure-side connection for both male and female ends. The anti-slip flange ensures stable bulkhead mounting to cut downtime. Brass dust caps and plugs are included for extra protection.
