Identifying tube material

[JackBinnie]

Hi Everyone,

Hoping someone can help me out, I’ve just bought some treadmaster mTec for the tubes of my rib and I’m unsure of whether the tubes are hypalon or pvc.
It says that Humber ribs use hypalon online but as mines is quite old I’m unsure.

It’s a Humber 5m but with Alpha 1 (black tubes). But their isn’t a metal identification plate on the transom.

Any help would be appreciated 👍🏼

(Apologies first post here and can’t seem to post a picture from my phone)

If it’s an Humber rib it should be hypalon

[JackBinnie]

Yes , just unsure as it’s been retubed at some point.

Scratch it with your fingernail if it removes small bits it’s hypalon no bits PVC

Tried earlier on underneath the tubes with a bit of sand paper and it seemed to just leave some scratches and dull, no residue.

Must be hypalon just not wanting to order the wrong adhesive

They use the same glue on PU and Hypalon. You can get the glue from an online Chandlers called IBS. There are several good youtube videos showing the process. You will need Acetone too...this not only cleans the surface but creates a molecular reaction that helps bond the glue. The two part glue is not expensive but you will find postage is expensive as both the glue and Acetone are flammable. If in doubt give Humber a call....they are in Hull. All the best.
