Butyl tape
Yet another was that it invariably oozed into the screw thread. Another problem was heaps of butyl oozing out the side. One problem was that with so much butyl to compress, it was quite hard to properly tighten the bolts without having to do it repeatedly. I started out applying butyl like a gasket, covering the entire area of the fitting. regards, allan All good advice, and here's one more pointer.
Here's a link to an excellent tutorial on bedding fittings (and lots of other good stuff) - very well worth reading. Also, it's worthwhile to countersink the screws before applying the tape. Preferably, if you have a screw/bolt with a nut, tighten the nut down rather than rotating the screw. One consideration though, where possible, its best to not rotate the fixing screw which tends to break the seal of the bedding compound to the screw shank. On a serious note, is it suitable for say sealing things like staunchen bases where a lot of compression is required? Does it of squeeze out the side of the fitting when the bolts are tightened? Hi Ashley, is it suitable for say sealing things like staunchen bases where a lot of compression is required? Does it of squeeze out the side of the fitting when the bolts are tightened? - yes, it does squeeze out the sides, so when finished you probably want to trim this excess for a neat appearance.
