DESCRIPTION
The PFS flange seals are designed for use on all hydraulic flanged tube, pipe and hose connections, 4 bolt split flange type, as detailed in SAE Standard J518c.  They provide a direct replacement for the o-rings without any modifications of the existing grooves. 
High pressure and pumping are common problems which prevent reliable sealing in applications where o-rings are fitted.  The PFS seal overcomes this. 
For SAE J518 4-bold Code 61/62 Split Flanges
