> Steve, Is the butyl rubber vapor wrap the same as Scotch rubber mastic
tape
(2228), which is available at the big box stores? I have been wrapping
joints
in two layers of reversed Scotch 88/33 (sticky side up), then overlapping
with
the rubber mastic tape, protected with another double layer of 88 or 33. I
only have about 5 years experience with the mastic, but connectors that I
recently exposed looked like new.
That's a James Dandy way to do it and highly recommended.
As far as the mastic tape, there are many varieties of butyl rubber
and other materials such as mastic. There's also a product for plumbers and
one for florist shops. 3M probably makes a dozen or more rubber products with
different voltage and temp ratings, etc. so it probably doesn't make much
difference which one you use. Just make sure you use your tape-vapor wrap-tape
scenario and you're good to go.
Cheers,
