1. Description
The B7 profile from Forever Seals is a non-symmetrical, hydraulic cylinder piston seal.
The knife trimmed, beveled lip contacts the bore to provide enhanced
low to high pressure sealing and wiping action. When installed, the
diameter of the B7 profile is stretched slightly to fit the gland. This
ensures a tight static seal with the gland and improves stability in
application. The B7 profile is available in Forever Seals proprietary urethane
compounds providing excellent wear, extrusion and compression set
resistance. The B7 profile is a uni-directional seal. Two seals can
be placed on a piston, back to back, in separate glands offering bidirectional fluid sealing.
