Generic silicone pump sleeves (caution)

If anyone already has, or wants to buy a silicone pump sleeve (especially a generic one), might want to read this.

So I’m definitely what would qualify as a “fast gainer.” I’ve had large gains in the space of only a few months. No idea why really, other than I suppose my body’s biochemistry allows for faster than normal tissue generation. This explanation would be the most logical I think, because I definitely recover very fast from injuries generally speaking.

Anyway, so I’ve noticed in the past month or so that my gains have slowed down significantly. When I first started pumping earlier this year, I would literally see size increases in length or girth, or sometimes both on a weekly basis. It was insane, and it was like that for about 3 continuous months. But something has changed. My gains have almost completely stalled. So I’ve been wondering what has caused this? Is it just the newbie gains coming to an end as my unit is now so conditioned that it no longer grows? Or maybe I hit my genetic limit? It turns out that it’s neither of those.

On Monday, my first session of the week, I noticed that I had developed a mild rash on the underside of my penis base. I knew what had caused it too. It was my silicone pump sleeve, even though I’m not allergic to silicone. It was the chafing that caused it. I first started using a pump sleeve when I upgrade my cylinder from a 2x9 to a 2.25x10 Vacutech thickwall cylinder with NO FLARED BASE. That’s an important distinction, because even though my BEG was 6.50” when I started using the 2.25 cylinder, I had problems with my nutsack skin getting sucked into the cylinder base. Several experienced pumpers gave me some good advice and I learned that this was happening because I was using a round thickwall cylinder at very high pressures, much higher than they were designed for. Also, the lack of a flared base was not only making it very easy for my nutsack skin to get sucked into the opening, it was also extremely uncomfortable because a rounded cylinder base with no flare digs really deep into the groin. That’s by design, as they are supposed to expedite length gains by increasing the amount of force on the suspensory ligament.

Anyway, so I ended up getting a silicone pump sleeve, and problem was solved….or so I thought. For the first three weeks or so I was still gaining with the silicone pump sleeve. Then all of a sudden my gains slowed down dramatically. Now after thinking about it, I know what happened.

Basically, the silicone pump sleeve I was using is just a generic one size fits all kind of accessory, and while it can fit a cylinder up to 3 inches in diameter, the interior opening is only 1.25”, but very flexible. That’s why I didn’t really consider it a problem, because although my penis is much wider than 1.25” (especially once the pressure increases), the interior opening was so pliant that it couldn’t restrict blood flow…..right?

Wrong. The damn thing was definitely affecting my blood flow. I didn’t know how much until I took it off this Monday, and did a session without it. Not only did I get much better and faster expansion during my session, my penis stretched out a good half an inch more than usual. Also afterwards my unit had LESS fluid buildup, and my flaccid hung longer and thicker.

Now it’s been three days of pumping without the silicone sleeve, and I can finally see the limitations that the pump sleeve was placing on my unit are disappearing. For instance:

1) I had been wandering for a while what was causing the left side of my unit to expand faster than the other, leading to a subtle bulge. It was the fucking pump sleeve. Removing it is correcting that problem.

2) I had been wandering for a while why my glans has dramatically slowed down in growth, as it’s usually the fastest to expand. It was the fucking pump sleeve. Removing it is correcting the problem.

3) I had been wandering for a while why my upper midsection has dramatically slowed down in growth. It was the fucking pump sleeve. Removing it is correcting the problem.

4) I had been wandering for a while why the underside of my penis was itching. It was the fucking pump sleeve. Removing it has corrected the problem.

5) I had been wandering for a while why the base of my penis seems to be uneven in certain spots. It was the fucking pump sleeve. Removing it is correcting the problem.

TLDR version:

Be very careful with generic silicone pump sleeves. They might be fine for a while as you grow into your cylinder, but once you hit a certain point, they will limit your growth by restricting blood flow. Proper silicone sleeves like what Pump Toys puts on their Velseal cylinders are exempt from this, as they don’t decrease the diameter of the opening. I’m talking specifically about the cheap generic ones.

And if anyone is wondering, yes my pumping sessions are much more uncomfortable now, and I’ve had to reduce the pressure. I still start at 10Hg an then go to 15Hg, but the increase is now done gradually. My final set is now done at 18Hg, with the last two minutes at 22Hg instead of the whole 10 minutes. However, even though I am using less pressure, I am getting FAR greater expansion and my unit is also being stretched much better as well. I thought about getting a Velseal cylinder, but I think I’m just going to stick with this one. Even though it’s extremely uncomfortable to use a round thickwall cylinder at these pressures, it’s also VERY effective for stimulating growth (especially length) and I can tolerate it now that my base is big enough to prevent my nutsack skin from getting sucked into the opening.

Sorry for the long post, but I had to get this off my chest, and I hope that anyone using these cheap generic pump sleeves will take a second look at them as they can potentially handicap your gains.

That’s good information, as I’ll be ordering the exact same cylinder in the next few days. I was honestly thinking of getting a silicone sleeve because I had one on a previous cylinder a decade or so ago but don’t recall enough to say If it restricted blood flow or not.

I currently use a LA Pump that I’ve had the last 4 years but it’s a regular/flared bottom so I’m excited to see how this thick wall does!!!

There are many sleeves and I’m also pretty sure it affects. I have only two, so can’t judge much about that, but both are quite different. One is more like rubber, it’s quite tight in both inner diameter and stretching. As result it blocks blood outflow much stronger and I can’t use very high pressure, because it becomes painful (usually around 6HG). Another one is extremely soft, it’s very thick, but it just makes tight seal without any restriction at all. With this one I can push up to 12-15HG. I had no very much of practice with both, but so far I see that as two different pumping methods. First one is much closer to clamping with stimulation. It has higher blood income than natural erection, but it blocks outflow as as well. Second one doesn’t have much of outflow restrictions, so it allows huge income and lets it return back. It’s just speculation, but I suppose first one might work good for EQ and second one for expansion. Because it’s much higher pressure I see huge expansion. 1 inch length for me (some of that is just cylinder pressing in pubic fat) and 1/4 girth and I must admit it’s the only exercise which makes my girth bigger. High pressure for sure works good as tissue stretching. At the same time tight sleeve really works with compression. It doesn’t have such expansion, because of lower pressure, but because outflow is blocked it makes dick extremely hard.

At the end I can’t say about results. It’s just speculation and just because it’s very hard in pump, doesn’t mean it can affect EQ in positive way. Maybe that’s just huge stress which leads more to trauma without positive reaction.

The round headed thickwall cylinder with no flare is one of the best cylinders you can get. It really puts some tension on the suspensory ligament. In fact, after removing that damn pump sleeve, my suspensory ligament is now feeling sore after a pumping session, which is a good thing because it means that it’s being broken down and that will lead to growth.

I don’t think you will need a pump sleeve unless you plan on using higher than normal vacuum pressures. And even if you do use high vacuum pressures, a pump sleeve won’t interfere with gains until you get too big. That’s what happened to me. It was fine when I was under 7” in BEG, but once I broke that barrier, it started being a liability and hindered my gains because I was too big.

That sounds similar to the one that I used, which you can see here. These pump sleeves can work well, but once you hit a certain size in thickness, they will start to hinder your gains. For me, that was when I hit 7.00" in BEG. At that thickness, it put a lot of pressure on my base and started preventing blood flow.

It’s always great to have positive feedback from a PE session. In this case; the soreness you get afterwards

What pump are you using? I was thinking of getting the thickwall starter kit. Some said leluv but I don’t trust china materials compared to something more expensive idk.

I have 3 or 4 LeLuv cylinders and have had no problems at all with them. I highly recommend them for their comfort, availability and price point.

I have two LeLuv cylinders and recommend them as a good quality product for the price. However, my LAPump cylinder has a wider base flanged rim which makes it more comfortable than The LeLuv Cylinder; however, it costs $50 or so more. For an additional $10, the VelSeal From PumpToys with the thick silicone gasket is by far the most comfortable.
