FS2700-LN ORFS Bulkhead Union with Locknut | Hydraulic Bulkhead Union Fittings
Collection Description
The FS2700-LN ORFS Bulkhead Union with Locknut collection provides robust hydraulic adapters engineered to pass a single ORFS (O-Ring Face Seal) fluid line through a panel, bulkhead, or structural surface while maintaining a leak-resistant connection.
Unlike standard union couplings, these bulkhead designs integrate a locknut to secure the fitting’s body firmly into a panel or wall, reducing movement due to vibration and mechanical loads.
