Over the weekend, I was finally able to complete a project that was on my list for over a year.
I have the original woven hose for my 1980 Electrolux Olympia One and it was so leaky that I had stopped using the machine altogether several years ago. Even though I did find a newer replacement hose with an on/off switch that is better in every way (longer, more airflow, etc.), I always felt sad that the original was kaput.
So I ordered a 22 oz can of Plasti Dip clear rubber coating from eBay and took the plunge. The hose was so bare and dry that even after I poured 2/3 of the can down one end, it didn't flow through to the other side. And no, no clogs as I had made sure the inside was completely clear, dry and as clean as possible before starting the restoration process.
After much hose rolling (think play-dough snakes), swinging, and high speed twirling, I hung it up to let it dry and several hour later, a few ounces of dip finally oozed out. I let it dry overnight and checked for obstructions with a long metal pole.
Being the testing nutjob, I grabbed a Baird meter and suction guage.
New replacement hose: 93 CFM and 78" of lift
Plasti Dipped woven hose: 77 CFM and 80" of lift
You read that correctly, the old woven hose now has slightly better suction than the replacement hose I bought two years ago. As you can see from the pictures, the woven hose has a kink in it and probably has a generally smaller air passage than the newer one, hence the 16 CFM airflow loss. While I expected maybe a 5-7 CFM loss, the original is now completely useful whereas before, it would barely pick up lint.
