The type SFA is a medium to heavy duty single acting rod seal which can also be used for piston application. Over the years, it has proven itself to be an effective and robust seal over a wide range of applications. The seal comprises a rubberized fabric which is bonded to a nitrile energizer and needs a split housing.
The seal section is pre-loaded by the housing when installed to ensure effective sealing at low pressure. When the pressure increases, the nitrile energizes the fabric to increase the sealing area and hence improving the efficiency of the seal. The strength and durability of the rubberized fabric combines with its ability to retain lubricant keeping friction and wear to a minimum.
