Re: Tef-Gel excellent price from National Supply

Duralac is special stuff, but has a shelf life, and it shortens above 20°C.

Hi ,

Did you ever try Duralac?

I have built 2 boats using this stuff. It is amazing and I believe it is better than Tef Gel.

In addition it is a cream and when it dries it is somewhat like locktite.  For example, I use it on my spurs line cutter and the

set screws (grub) on my propeller. After 2 years it is still there and is a bit stubborn to remove—not like epoxy but you know that he screw is not going to loosen.


One tube will last many years.

Hi All,
   My  boat-local West Marine ran out of Tef-Gel so I went online to order some and found a supplier that is much less costly than WestMarine...well that isn't saying anything novel is it?  It is cheaper than Amazon too!  By a lot.     Tef-Gel is the goop that you use when connecting two dissimilar metals, like bolting the furling gears to the boom or mast, solar panels to the SS arch, and for external electrical connections.   

I have no connections to National Supply ...except being the guy who just bought five tubes.
