China Da17 P8 Double Acting Wiper Seal Scrapers Dust Seal

Description
The P8 profile is a stepped double acting wiper seal composed of two rubber wiping lips. This Double Wiper exerts inwards the wiping function of a U-ring, and a wiping action outwards against soiling.

Design standard
Busak+Shamban DA17 series and Merkel P8 series may be referenced for design.
Advantages
Low friction
Wear-resistant
Easy assembly by deformation
Good wiping effect, both internally and externally
Very good sealing effect against residual film of oil on the extending rod

FKM 90 Shore ANBRNitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.

Chemical resistanceAliphatic hydrocarbons (propane, butane, petroleum, diesel fuel)
Mineral oils and greases
Fire-resistant fluids (HFA, HFB and HFC)
Diluted acids, low-temperature alkaline and saline solutions
Water (up to +100°C max)Compatibility issueFuels with high aromatic content
Aromatic hydrocarbons (benzene)
Chlorinated hydrocarbons (trichlorethylene)
Polar solvents (ketone, acetone, acetic acid, ethylene-ester)
Strong acids
Glycol-based brake fluids
Atmospheric and ozone agentsTemperature range-30°C / +100°C in dynamic applications (+120°C in static applications)

FKMDepending on their structure and fluorine content, the chemical resistance and resistance to the cold in fluororubbers can vary. This FKM-based rubber is very often used for high-temperature hydraulics and pneumatics, for industrial valves, injection/fuel systems, motor seals and high-vacuum systems.
