Stan,
I realize there are options out of the united states but I am seriously tired of getting raked over the coals on prices and shipping and brokerage and duties !
So I have put in an inquiry with regards to the new HydroVac units from fleet products and they will let me know if the piston seal used is a leather material or an updated material.
They also offer a 1 year warranty on the product.
I'll keep you posted
