How can I apply base silicone sleeve into my cylinder?

Hello to everyone.

I have a 2 inch thick leluv cylinder, and a few days ago I ordered a Leluv base silicone cushion sleeve. According to the chart I ordered the right size for this cylinder.

The thing is that this sleeve has like an opening hole in the center, and my penis doesn’t fit into, and if I force my penis in, it starts to strangle.

I’m adding photos, I don’t know if it’s like that or I’m doing sonething wrong.

Thanks!

No, that’s how they work. They’re more like very tight cock rings that help seal the tube than ‘seals’. Unless you have a very small girth or are using a ridiculously oversize tube, the LeLuv seals are useless. I got suckered into buying a set as well.

LeLuv generally has good quality stuff, but those seals are worthless trash.

Worse: I haven’t found anyone else who makes a decent seal, either.

I have found that the Pumptoys Velseal is about as good as it gets….

Yeah, those look nice. I get a stabbing pain in the wallet when I look at the order page, though.

When I finally move up to higher vacuum I may have to bite the bullet, though.

That’s a shame. It was my self christmas present. It takes me some ammount of time to order products from USA to my country, not considering the shipping costs.
Now I have a 3 pack of useless seal sleeves. My first thought was that seal would just fit perfect because they were from the same brand.
Thanks for answering

My experience of silicone sleeves is with cheaper eBay versions. Pretty decent quality though. The opening has to be narrower to create the necessary seal. I had to use a fair bit of lube on my dick to ease it through the opening, more than I would normally use when pumping. The problem then is keeping the lube away from the scrotum to avoid it getting sucked into the sleeve and thus defeating the purpose of having the sleeve in the first place. Not easy to achieve.
