Description: Extruded Neoprene EPDM 60 Durometer Profile
Uses: Williams Everlastic 2nd Seal is placed prior to the primary seal assuring a watertight seal should the primary seal fail. The 2nd Seal can be used in verticle and horizontal applications or as a primary seal when appearance is not an issue.
Features: Excellent movement capability in extension 250% and compression 50%. No stress on bond line unless exceeding 250% in extension. Excellent adhesion when butting together using 2nd Seal adhesive. Easy to install. A must to assure leak free performance for the long run.
Available sizes: For joints 1" to 4"	Tech Data? Click Here
