Spiral Wound Gaskets (SPW)

The metal strip provides the basic structural element, while the filler material provides an excellent seal. This combination of materials means that spiral-wound gaskets may be used under fluctuating temperature and pressure conditions. Depending on the intended application, spiral-wound gaskets may be specified with or without an outer and inner ring.

• Graphite is usually used as a filler material. 
• Other materials are only used if graphite contaminates
• the media or is not chemically resistant.
