Cylinder Sizing

Hey guys. I am fairly new to PE, especially to pumping, so I need some help. I’m going to purchase a pump at Welcome to lapdist.com. My current sizes is approx. 6x5 inches. What proper size of cylinder that I should order. Thanks in advance.

9”x1.75” :up:

I’ll second that.

I am approximately 6.6 x 5.5 based on last measurements and I have recently ordered the 10”x1.75

You would be better off with a 10X2 or a 9X2. With your 5.5 girth, that 1.75 tube will be too small. If you can, send them an email or call and ask them to change it for you. I myself would prefer the 9X2, just so you don’t have that extra cylinder length to mess with.

Thanks for the replies guys. I just don’t seem to understand, why can’t I use a 10x2 cylinder? Why should I use a smaller one? Will I get any best results with the smaller cylinder?

With your girth of 5 inches, you will have trouble keeping your balls from being sucked into the 2” dia cylinder. The 1.75 cylinder will be a more comfortable fit and will take you up to at least a 5.5 girth. Once you are at 5.5 girth, the 2” dia tube will be next.

As far as length goes, I think the 9” tube is plenty for you current length.

I haven’t thought about that. So you guess there’s no way for me to use a 2” cylinder as my balls will be sucked into it or I can give it a try holding my balls when pumping or something else?

Of course you can give it a try.

If money is not a problem, the best solution would be to order both the 1.75 and 2 inch tubes. That way you can start your routine with the 1.75 and once you pack that, you will be ready to transfer over to the 2.0 and continue pumping.

Gprent thank you for your advice; call it ignorance if you may however for some strange reason I went onto lapdist site and checked their recommendations based girth measurement and it for the 5.5” girth a 1.75 was recommended. Gprent wish i had spoken to you earlier….I order it 2 weeks ago and it should be here in the UK by Monday.I guess will have to order a new cylinder. Gprent; if length is currently my main goal at this stage would you recommend that I still use or try to use the 1.75 cylinder until the 9”x2” arrives?Do you have any idea if their their pumps compatible with other cylinder? Any input would be appreciated.

Thanks a lot for your help. I guess I’ll order both.

Phenyo,

Why don’t you make Mad Dog a nice offer for your 1.75 cylinder? :)

You can use the 1.75 cylinder, but once your shaft fully packs the tube, then all of the vacuum pressure is acting on just the surface of your head and you have to be careful to avoid getting water blisters. So you should then keep the pressure below 5”hg and limit your time to 10 minutes.

I would say that just about all major pumping systems use the same quick disconnect male/female connectors, so the cylinders are interchangeable.

Phenyo,
Why don’t you call the place you ordered it from and ask them to change the order? Tell them that you will gladly refuse the shipment when it arrives to ensure that it has not been opened and also pay the shipping cost for the new cylinder. I would think that would be an acceptable solution for you and them.

Good luck and good gains!

They won’t replace the cylinder.

@Phenyo

I just wondered if they confirm the order before shipping? A guy have ordered a pump at Welcome to lapdist.com on Friday, received the ‘invoice’, and pure silence then.. Would you please tell more in detail about the order.

It’s a bad idea, I think. Have a look where I’m from.. :)
