A multi-layered lip seal comprising a dynamic layer optionally having a filler incorporated therein and a static layer optionally having a filler incorporated therein is described. The lip seal has an annular ring shape, wherein an inner diameter of the ring shape is curved in an axial direction so as to give the lip seal a J-shape when viewed from a cross-sectional perspective. Fillers that can be included in static layer include stiffening filler, reinforcement fillers, conductive fillers and/or abrasion resistance fillers. Fillers that can be included in the dynamic layer include wear resistance fillers. The use of specific fillers in specific layers of the multi-layered lip seal allows for certain segments of the lip seal to be imparted with the benefits of the filler without negatively impacting other segments of the lip seal.

Multi-layered PTFE radial lip seal

A spiral wound header ring is provided. The spiral wound header ring comprises at least one outer fabric layer and at least one spiral of inner fabric and rubber. The spiral wound header ring further may have a sealing surface that extends from a rearward facing surface to the forward facing annular, radially extending, surface.

A method for making high-pressure sheet gasketing material is provided that employs an elastomer, such as natural rubber and/or acylonitrile-butadiene rubber. Tert-butyl acetate is added to dissolve the elastomer. Other components may then be mixed with the dissolved elastomer and may include, for example, antioxidants, colorants, curing agents, curing accelerators, reinforcing fillers, and fibers such as organic and/or mineral fibers. The resulting dough may be formed into a high-pressure sheets, for use as gasketing material, using a two-roll sheeter machine, or the like.
