Resizing the tube

Hey guys,

I own a Bathmate Goliath which has a diameter of 2.59" and I probably need a tube of 1.75" to 2.00" (my size is in signature and am using this as a guide Selecting Your Cylinder Size). I was stupid and got sucked into buying that specific one because it cost less at the time and had extra goodies which came with it.

Is it possibly by any means to somehow reduce the diameter of the tube. I am not sure if anyone has been successful in doing this, rather than buying a new one would be a waste of money IMO. I mean it does give me temporary girth expansion but I would like to use it for length as well.

Not sure if you can get a mold to fit inside with a hole in the top or if there is an easier alternative.

Help would be appreciated,

Thanks :D

That’s a ton of work bud. Better off just buying a new cylinder and pump.

Just out of curiosity, if you use this size selector, what do you get?

You can buy a pump sleeve. works with the BM too . It narrows the diameter a bit and gives a better seal.

In the end if you want to do PE the long run nothing beats a real pump with gauge etc.

How I forgot about a pump sleeve is beyond me. I used one when I was using my bathmate. It was cheap on ABSilicone

It seems to be mainly based on length, while girth should be more important.
The bathmate is in theory an advanced tool only. You can do too much wrong too fast.

That’s not much of a size selector. It will not seem to accept any longer than 7.0" or thicker than 6.7"
It sure wants to sell me a $300 Goliath pump with express shipping at the checkout though!

lol. And please add some penis pills for 59.99

Gprent. It recommended the Goliath which I have. Seems to be only taking the Hercules or Goliath model into consideration.

How does the sleeve work? It just looks like a rubber ring. Can that make it focus length more?

I have often wondered about that too. Also how are you supposed to lube it? I have tried to water pump with a similarly sized cylinder (try saying that three times real fast) but it was not very easy or pleasant to penetrate through the seal with just water for lube. I tried soaping my meat up real good too but the water just rinses it away before I can slide in.

Man obviously your girth is one in a 100 000 .

You wont fit into products made for the other 99 999.

The large pump accepts a 2.59” (60.0 mm) max.diameter and 9.84” (250.0 mm) max. length.
Their medium one is 8.46” x 2.20” .Their online sizer only seems to accept dimensions for their smallest x30 hercules models.

The large one will fit me but their medium one 8.46” x 2.20” is too short and I would be packing too much because the pump I currently use is 2.25” and the middle to end of my shaft and my head is already squishing against the cylinder wall.

I was just wondering how to lube their seal when it is a water pump. Water is not a good enough lube. It will hurt my head and shaft skin sliding against rubber with no lubricant.

If the seal is too big, it can be dangerous because it may suck in too much around my base and even my balls!
Their gaiters are black so you cant see what is happening. I like to see what my base is doing inside the cylinder so I know how much it is packing because I don’t want to gain any more useless base girth. I like my club shaped profile. What does the cross section of their gaiter look like? Does it have an inner wall? How do you lubricate it?

It has horizontal intendations wall as the gaiter is compressed. If you are too big at the base it sucks skin in which results in “gaitor” bite.
Thats why many use a sleeve that is also used for pumps.

Its not such a great tool as a normal pump with gauge which can be fitted with water add on too.
