FS2650 ORFS Union Cross | Hydraulic Cross Fittings with O-Ring Face Seal
Collection Description
The FS2650 ORFS Union Cross collection consists of forged steel four-way hydraulic cross fittings designed for SAE O-Ring Face Seal (ORFS) connections. These union crosses enable four fluid lines to intersect at a single point while maintaining a leak-resistant seal using flat-face O-ring geometry.
A union cross is often utilized in complex hydraulic manifolds and distribution networks where multiple branch lines must be arranged compactly with consistent sealing and minimal pressure loss.
Pressure Ratings
