Expansion joint profiles 21.50 x 40 mm – 12 m for expansion joints 20–30 mm wide

Expansion joint profiles made of flexible rubber, designed for temporary sealing of expansion joints 20–30 mm wide. The profile is reusable in injection sealing applications using acrylic gels. It is supplied in 12-meter lengths, which can be cut to shorter lengths. Sealing plugs (MG1 200002), which are attached with adhesive, are used to close the end of the profile. Once placed in the expansion joint, the profile expands within the gap to seal it by pumping air into it. Injection needles (MG1 02025) are screwed into the installed, expanded profile, through which acrylic resin is pumped.
