Forkin’ seals...

They are for Triumph T120/140/150/160 disc type sliders & may also fit the earlier drum brake aluminium sliders. I have these in my TR7 & recently sold OIF T160. I have also fitted this make to a couple of T160s, Hinckley Triumph, Honda RC30, Ducati 888 to name a few. They are top quality & don't seem to give problems.

Great, any of these to fit Norton tubes?

Not that I am aware of.

I clean my forks after every ride to keep sand or grit off. I have no luck with fork seals. They weep no matter what. Carry a rag. Or make the seals out of wool. I hear the Brits manufacture a damned fine wool.

When new fork seals leak it's usually because they incur micro-tears as they travel down the stanchion tubes on the way to their destination.

Even on new stanchions it is advisable to slide them into place using a bit of plastic wrap or a baggie with a hole in it. A little lube won't hurt. Once the seals get to their destination, gently pull out the prophylactic plastic.

Fork seals give me between 20 and 30,000 miles service when installed this way.

i found this forum, as i was searchin seals to my 76 bonnie. good! so i joined. i'm from Finland, so please be patient my misspellings

I think leaking forks can be more to do with poor quality stanchions than poor quality seals. I bought a new "Made In England" pair of stanchions for a B50, as the original chrome wasn't good. I had to heat the bottom yoke to get the originals out but the new ones slid through without any effort. I measured them both and the new stanchions were .007" smaller than the originals. That extra 7 thou might have been enough to turn a just about OK seal into a good one. I suspect a lot of modern T140 stanchions are also of variable quality. Being made in England is no guarantee of quality.
