Best Source Of Replacement Silicone Sleeves

I’ve started vac extending but anywhere the metal rods touch the silicone sleeve it begins to breakdown and holes are made, even where the bar is smooth.

I’m assuming it’s because the silicone with the suction is under a lot of stress and the friction, even light, against the rods causes it to fail.

I’m curious if anyone knows of a solution so the sleeves can last longer and/or where I could attain them more affordably.

10-15 or even 20 bucks is too much for an item I don’t seem to be getting many uses out of.

I’m assuming if I hang instead the lifespan of the sleeves would be greatly prolonged, and am debating making the switch, but for now the extender has been really awesome since it’s so easy to put it on, pull on some pajama pants and I can more or less do random things at home and am not stuck in the bathroom for hours.

Any help in sourcing sleeves and/or prolonging their life would be greatly appreciated.

I haven’t a clue. They should be easy to find and to buy. I use mine with a home made down the leg type stretcher, and they tend to “give up the ghost” as it were, after a couple weeks. I’m now down to my last one. Been scouring ebay and amazon. I wonder if a person can’t just buy silicone tubing by the foot. You would think they would be manufacturing this stuff for something other than penis enlargement.

No matter how anyone uses them, they wear out - there has to be a cheap application people are using them for to get them at a reasonable replacement price.

I’m also in need of some sleeves. I’ll post here if I find some.

Happy hunting. I ran across a video of someone making their own, and that seemed as viable and economic a way as any I’ve found.
