Will this tape repair a cracked / separated / broken, metal non-bendable electrical wire conduit?

Will this repair a cracked / broken metal, non-bendable electric conduit?

I live in the northern most border of Minnesota and the conduit break is in an unfinished attack that stays dry but gets really cold in the winter. The metal conduit is completely separated at the break. The break that now separates the conduit is about 1" long, so there is an inch of electrical wire exposed. The electrical wires inside of the conduit are fine, just the metal conduit (AKA wire housing or wire jacket) itself is broken Rather than removing the non-bendable metal conduit from the break to the outlet and restringing the wire inside of a new conduit, I am thinking that this mastic tape [Or perhaps some other product?] may be capable of basically joining the broken metal conduit back together in an improvised sort of repair? . Thank you for any thoughts, advice, etc..

Customer Reviews

Scotch 1 in. x 10 ft. x 0.065 in. 2228 Rubber Mastic Electrical Tape is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from This stuff just plain works! I've used this product to waterproof many coaxial cable connections that were exposed to weather. Even after prolonged outdoor exposure, the seal has remained tight and waterproof. Seems to resist UV exposure well. Cost may be a concern at about $1 per foot, but this stuff works!
