The PAE seal type is specially designed for heavy duty applications.
When the coupling clearance between bore and piston cannot be reduced and the pressure is very
high - above 250 bar - the PAE seal type, thanks to a strong anti-extrusion ring, is among the most
appropriate of seal types.
The material used for the seal is polyurethane C0- type at 93 Shore A with high elasticity module. The
anti-extrusion ring is made of acetylic resin R0-type reinforced with fibreglass and with high tensile
strength.
Compound reference: CR
The assembling of this seal is done in semi-open groove.
The anti-extrusion ring should be installed after theseal.
It is important to remove any flash or cutting edge on the piston not to damage the seal during the
overlapping.
