Description
When you’re building custom hydraulic lines or need to connect hydraulic systems through a panel or firewall, this bulkhead union does exactly what you need – it creates a secure, leak-free connection that passes through a barrier while giving you reliable hydraulic flow on both sides. Perfect for those times when you need to route hydraulics cleanly through cab walls, equipment panels, or anywhere you need a professional-looking connection that won’t leak.
What You’re Getting
- Dual male OFS (O-ring Face Seal) connections with 1-7/16″-12 threads on both sides
- Includes locknut for secure mounting through panels or firewalls
- Steel construction handles high hydraulic pressures and daily use
- O-ring face seal design ensures reliable, leak-free connections
- Direct replacement fitting – no adapters or modifications needed
Built for Real Hydraulic Work
O-rings appear everywhere on modern equipment – hydraulic fittings, fuel system connections, oil filter housings, coolant joints, and air system fittings all depend on these simple but crucial seals. This fitting is designed for hydraulic systems on tractors, implements, and equipment where you need to pass hydraulic lines through walls or panels while maintaining system integrity. The OFS design is what you’ll find on quality hydraulic equipment because it seals better than pipe threads.
Made to Last
Steel construction means this fitting won’t crack or fail under pressure like cheaper alternatives might. Despite their simplicity, O-rings face harsh conditions. Heat cycles cause them to harden and lose elasticity. Chemical exposure from fuels and fluids degrades rubber compounds. The O-ring face seal design protects the sealing surfaces and gives you years of reliable service in tough farm conditions.
Installation Notes
The locknut lets you mount this union securely through any panel thickness you’re working with. Clean sealing surfaces thoroughly; scratches or debris prevent proper sealing. Lubricate O-rings with compatible fluid before installation to prevent rolling or tearing. Make sure your hydraulic lines have the matching 1-7/16″-12 OFS fittings – this creates the sealed connection your system needs.
