Multi lip rod seal, for medium to heavy duty applications, composed of a header ring, 2 vee rings and a female adapter.
The header ring is the primary seal. It is a bonded construction of rubberised fabric vee ring and rubber. When installed the section is pre-loaded to seal at low pressure but has the strength and durability of the fabric to operate at higher pressures. Rubberised fabric is also used for the vee rings. These provide secondary sealing as pressure acting on the header ring spreads the vee rings increasing the sealing area. The female adapter provides the support and protection from extrusion damage. It is manufactured in either polyacetal or hard rubberiesed fabric. The assembly is a pressure activated packing that does not require any axial pre-load.
