The FSA seal type (SAE Flange) has recently known a significant development in all static applications where a normal NBR O-ring would not resist to pressure and high coupling clearance.
The specific profile and the high modulus of elasticity, together with an excellent compressionset, avoid extrusion and leakage problems in the tube flanging.
The proposed material is a “C0” type polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance.
Compound reference: C0
Excellent abrasion and extrusion resistance.
It is important to remove flashes or cutting edges in the housing to avoid damages.
It’s also recommended to make a lead-in chamfer for easier assembling.
The installation in open housing is extremely simple
