Mityvac cylinder small cracks

Seems to be small fissures or crack in my cylinder. Idk how since it’s never been dropped and I keep it in a padded case.

Is it still safe to pump with?

Looks suspicious. Did it came this way?
Are they deep?

I just smashed my 2.5" cylinder into a metal thing in my bathroom. It seams to not have been damaged. It's Acrylic / Plexiglass, so they are really durable. But I do not recommend to smash them into metal things in your bathroom (an accident).
 
Once a small crack is form, the crack continues to grow larger under pressure. I have aquarium tanks and pressurized containers that gone bad during uses. Get it replaced. It will collapsed under pressure enough time and pressure. Splintered plexiglass is not a fun thing to deal with when your penis is inside it.
 
Using alcohol on some clear plastics will cause cracks. My Leluv cylinder got them after cleaning with alcohol.
Yes plastic materials/rubber and alcohol, are not a good combination.

*Edit: I believe some plastic can be resistant, but I will not do the research on that now.

I've been using my pump for over a year (on and off) and I've never had a thing like this. It might have happened due to the influence of something you might have used to clean the pump (I'm just guessing out loud).

I once had a dream that my mityvac cracked while I was pumping. I woke up scared. This happened a few months ago.

Good thing is, MOS will replace the pump for you.
 
How can I tell if my rube is damaged? It won't hold the vacuum. But I'm pumping for length, so I'm not sure if the tube is damaged or because it's so narrow, that the fit isn't right.

If you're using the MityVac, put together the water vacuum system. Fill the entire cylinder full of water. Press the base of the cylinder to your stomach to create a good seal. Pump slowly and observe to see if there's any water seapage anywhere.

If you're using an old pump cylinder set that doesn't have a water trap, this will be very tricky. If you have a blue or red light, go into a dark room, shine the light inside the cylinder and inspect the cylinder wall for any crack. For air pressure leakage test, you will need to submerge the cylinder in the water while you pump. Look for air bubbles escaping the cylinder parts and hose connection.

Thanks man. Do you think it's a good idea to pump for length everyday?
 
Pumping, depending on the cylinder size, tends to max out about 30% efficiency. This is why manual stretches were introduced to the pumping routines, or better yet, the Legth Master as part of the length routines. The amount of tension or traction force that you can put on is ridiculous. If you compare the Length Master to manual pulling by hands and pumping for length, pumping is 30%, manual hand pulling is 50%, where Length Master is 100% plus with only 35% or so energy used. The only key factors is the consistency and the gradual intensity. Pumping will literally takes 3 to 4 times longer than the Length Master force traction. All day stretchers and traction will take 2.5 times longer, and manual hand pulling will take around 2 times longer due to the lack of upper intensity loading. Your arms may have the strength to bench and lift 100lbs easily. But consistent holding with grips on a small flaccid penis in a pattern at 10lbs is not possible. We tried. We failed. This is why the Length Master was born. Those who have 8in and 9in length to start with are blessed since you can wrap and have some good holding length. Those who are less than 7.5 tend to be on the short end of the stick, or dick (pun intended) for proper gripping.

But if you're looking for girth, nothing beats the pumps.
 
I use a baby bottle brush and dishwashing liquid.

It's a good idea to run some hot water through the hose every now and then, too. There's no practical way to brush it out. Lube can work its way along the hose to the pump, and if it dries out, it can gum up the pump.
