What material do you use for stuffing boxes?
What material do you use for stuffing boxes?
Fiberglass home insulation products. Comes in yellow to match what's already in most of my JBLs.
". . . as you have no doubt noticed, no one told the 4345 that it can't work correctly so it does anyway."—Greg Timbers
This thread has links for a treated fiberglass insulation that is non shedding and is identical to the vintage JBL material as well as working better than just about everything else I have tried... I do like Sonex foam better, but it is rather costly. I am not sure if you can get the same brand or type of fiberglass in Europe... I believe over there rockwool is more common... and seems to behave very similarly.
