Durlon® SWG Style DR
Durlon® Spiral Wound Gaskets are made with an alternating combination of a preformed engineered metal strip and a more compressible filler material which creates an excellent seal when compressed. The engineered shape of the metal strip acts as a spring under load, resulting in a very resilient seal under varying conditions. The strip metallurgy and filler material can be selected to seal a wide range of applications. All Class 150 & 300 Durlon® SWG styles have been engineered to precise manufacturing tolerances and utilize optimal winding density that allow for lower stress (bolt load) sealing compared to conventional spiral wound gaskets thus eliminating the need to stock both standard and low stress SWG’s.
Style DR
Sealing element (D) combined with a centering ring (R) which reinforces the gasket and acts as a compression stop
Commonly used with standard raised face and full face type flanges
Centering ring is epoxied which provides superior corrosion resistance compared to powder or liquid coating
