7695, a proprietary polyurethane compound, is compatible with mineral oils and
water, solving seal problems associated with water degradation. The compound
is also compatible with vegetable-based hydraulic fluids. It is resistant to
hot water to 250° F, making it a possible alternative to chloroprene and
ethylene propylene rubbers.
