CalExotics Universal Silicone Pump Sleeve - Clear

This is not an exaggeration, this sleeve is very thin and can tear easily. It also states that it can be used up to 3.0 inch diameter,"this is untrue"! 2-1/2" is about the max. At the end of the day its your call. I bought this because of the 4's and 5's, the fact is that is does not fit a 3 inch pump.Will this work on a smaller pump, I do not know. However if you have a 3 inch pump dont waste your time on this one.

I ordered this pump sleeve along with a pump cylinder and also an additional sleeve of a different brand and different design. Why did I order two different pump sleeves? Because everyone has slightly different anatomy, and thus, I knew there would be a certain degree of trial and error when it comes to finding a sleeve which would work. The whole purpose of the cylinder sleeve is to provide a perfect seal around your member once it is inserted into the cylinder, thus is MUST be a perfect fit as well.The other brand that I ordered which is the "Size Matters Comfort Cylinder Seal". That one failed completely but it's a very different design as compared to the California Exotic Universal Sleeve.On the other hand the California Exotic Universal Sleeve worked perfectly! The main difference is that the Universal Sleeve design in my opinion is superior to the Comfort Cylinder Seal due to the fact that the Universal Sleeve has an inner sheath that gradually tapers down in size on the part that actually seals around your member. This gradual tapering is what actually creates an effective seal.The only disadvantage that I could see to this design is that if your member is already close to the same girth as the cylinder itself, the sleeve might rip towards the smallest area of the inner seal. But if you of normal girth, this shouldn't be a problem. If you are of greater than average girth than perhaps the Size Matters Comfort Seal may work better for you because it doesn't have that gradual tapper, rather it's just simple o-ring design.Something you should be aware of is that it seems that this sleeve as well as all other sleeves/seals seem to work best with plenty of lubricant applied both when attaching the sleeve to the cylinder itself as well as to your member when you are ready to insert it in to the sleeve. If you take a break in between pumps, when you go to re-insert your member, it's a good idea to apply more lube again.Also, before you actually use the sleeve, I recommend you soak it for several minutes in warm/hot water. No, not boiling hot, but just water as it comes from a hot water tap. This will allow the silicone to soften up a bit and allow it to stretch more easily and lessen the likelihood of it ripping.Be aware though, that at some point all sleeves/seals will rip, so first experiment a bit and find out which seal works best for you, and then once you find one that does the job, order several of them at a time so you always have a replacement on hand.

The pump sleve is nice and all but it's too thin. This normally wouldn't be a problem but the seller says it's universal but with the sleeve this thin it's simply not true. If your motive was to make a universal sleeve cover than make it thicker because this little thing will rip if you put it on any pump over 2 inches

I purchased these because I have a "Full Range" stereo.Sounds odd huh?The lies about "full range" told to consumers is of course a technical LIE. (no consumer grade stereo sold is "full range")A Full Range stereo reproduce frequencies from 20Hz to 20KHz at an SPL (Sound Pressure Level) equal to or in excess of all other frequencies.The "lie" occurs at frequencies below 80Hz.These bass frequencies when reproduced Factually and Technically as Measured cause a wonderful improvement in sound enjoyment but also cause a technical / physics problem.The problem is... frequencies 60 Hz and lower cause profound physical vibration.These frequencies (when "properly" reproduced) DO CAUSE CD players and DVD players and Blu Ray players so much vibration that the player will skip and or hang up. The player is literally vibrated too much.The solution is vibration isolation.Get the picture? (FYI my stereo weighs 3,000 pounds and it deafens no ears because it was tuned by a professional physicist)So, these silicone donuts work wonderfully as vibration isolation.PROBLEM.... these silicone donuts sold are NOT what is described.These silicone donuts are very thin and not soft silicone.These donuts are thin and leather like and provide ZERO vibration isolation.My previous donuts are roughly a half inch thick and soft squishy silicone that breaks down over the years.I required replacements.These CalExotics Universal Silicone Pump Sleeve items are useless for that purpose.I wager that they are junk for their intended purpose as well. (I wouldn't know)

Got this to replace one original. This works 100% better. It it tight though. Guess one needs to apply more lubricant.

I'm not sure why other reviewers are saying this is expensive. Compared to the advanced silicone sleeve, California Exotic Novelties offers, as a add on, with their California Master Gauge Penis Pump, it's a bargain. You might want to see my 1 star review for this pump, for what I had to do, to get it to work consistently. But, the sleeve worked beyond my expectations. I had to cut a couple of the rings off of it, to fit my member. Two things I've learned about pump sleeves, is that one size does not fit all, and all sleeves don't work for everybody. For some reason I was not able to check out with just the seal, from California Exotic Novelties. I had to buy it from an alternate seller, Green Web.

I purchased the item thinking it would help cushion the tube and make a good seal . The fist time I used it , I put it on the tube . it went on easy . I put some lube on it then insert my self . it must not be very good silicone because it split in half . I wont be buying this item again .

Fits Venus tube perfect. This is the third one I have bought lasted about one year not real durable but the best I have found as yet. The slots tear out after a while.
