S55013-1000-46K | Seal

I.D. stepseal offering a high static and dynamic sealing effect, high extrusion resistance, low friction, high efficiency, high abrasion resistance, and high operational reliability. The sealing performance of the stepseal results from the hydrodynamic properties of the seal. The seal edge creates a steep contact pressure gradient on the high-pressure side and a shallow contact pressure gradient on the low-pressure side. The controlled pressure gradients minimize fluid adherence and enable residual fluid to be returned to the system. The O-Ring relief chamfer reduces pressure loading on the seal, improving contact and sealing performance at high service pressures. The special high-lift rear chamfer combines a smooth downstream sealing face with the ability to meet large radial clearances and hardware tolerances.
