Homemade Penis Cylinder And Seal

I’m sure everyone is familiar with using a fish tank gravel cleaner as a cylinder. I’ve always struggled with how to create a comfortable seal. I’ve just discovered a great solution. I’m new to this forum so forgive me if someone has already shared this. Buy 100% silicone caulking from the hardware store. Put some water mixed with dish washing soap in a bucket. Squirt some caulking into the bucket. Knead the caulking in the water for a few minutes until it starts to get firm. At that point I roll It in your hands and apply to the cylinder. Work it around the inside and out to form a half inch lip around the whole cylinder and hang upside down to cure. The result is super comfortable seal for your homemade cylinder. The entire cylinder and seal ran about $25.

I’ve never heard of this, but now that I look at one on Amazon, they look downright pornographic. I wouldn’t be surprised if someone in one of Amazon’s Q & A’s asks, “Can this be used to make a penis pump?”

You can buy a real cylinder from leluv for around 30 bucks on ebay. I am sure you can afford that.

Selecting Your Cylinder Size

Plus $32 shipping and a cheap little flare instead of a seal. Thanks but no thanks. This homemade seal is a lot more comfortable.

For the tape, try FlexTape.

I bought a roll of extra wide stuff to fix something on my roof. It’s super sticky and I bet it would work well to make the surface mate nicely against your skin.

I’m picturing making a silicone ring for the base using a plastic bottle or something like that as a mold and then putting FlexTape over it to hold the silicone ring in place and make it durable.

Just to set the record straight, the shipping is free, but as long as you are happy, that’s all that counts. :up:

Hey Phil, with this technique you won’t need to make a mold. Once the silicone starts to stiffen just mold it to the cylinder with your fingers. Work it into the shape you want

Hello I’ve been looking for something like this for a while ,I have a 3 inch x 9 inch inch cylinder that really hurts my pelvic area once I hit 10 -15 g I feel like I have more potential to put more pressure on my penis but the tube is against my pelvic bone and it hurts .I will be buying this tomorrow thanks it has to be 100% silicone right?

Hey the types of acrylic are different between a gravel vac and a Penis pump. Plus the thicknesses are about twice as much to take a potential higher pressure. I have seen gravel vacs crack and I can’t imagine the risk of shattered acrylic vs $30.
