Leather seals, such as cups, flanges and u-packings take on the shape they need in order to seal. It may sound strange, but if you’ve got a little bit of wear, or you’re a bit out of true, leather is going to fill the voids whereas the rubber or plastic cannot. They just are not flexible enough.
We are proud of our strong relationship with one of the nation’s largest manufacturer of paint spraying equipment. Our leather seals are used in their fluid handing systems and components from small paint spray pumps to large automotive electrostatic painting equipment, lubrication and sealing applications, as well as power applications for the contractor industry.
They have found that leather impregnated with synthetic rubber, used in conjunction with plastic seals, is a combination that just cannot be beat. Their engineers say, “Leather is more that a good seal, it is an excellent bearing. When pumping abrasive materials, leather absorbs abrasive particles without seal damage, and these impregnated leather seals can be used with both water and solvent based paints.”
All from leather.
