RWI-RJ - Windings with inner and outer (centering) ring
- Spiral winding (sealing element) consists of preformed metal and soft filler material
- Centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter
- Inner ring prevents radial buckling and shields the sealing element from erosion caused by abrasive media
- Ideal replacement for solid metal oval or octagonal API ring joint gaskets
- Saves cost of flange replacement when gasket groove is badly worn
- Fast and easy installation requires only a 3/16" (4.77 mm)flange separation [ring joint gasket may require as much as 3/4" (19.77 mm)]
- Wide variety of metal and filler materials have a full range of temperature and pressure capabilities
