O-ring seal Advancap™

elastomericpiston

The Advancap™ rod and piston seals are designed to provide a cost-effective cap seal solution that prevents extrusion and eliminates O-ring spiral failure in dynamic applications. Each seal combines a cap made from Avalon®, our PTFE material, with an elastomeric energizer, and is available in configurations for zero, one or two back-up ring glands per AS4716. Custom configurations are also available. The Advancap can replace low-friction, O-ring swivel seals that leak, nibble and/or exhibit excessive friction.
