I understand but I'm not looking to ever go past 5hg. So I don't know why would that be an issue.

I have found some online, ie leluv's but I do not know if the gauge/device matches the hose's end. In other words I do not know if it will connect successfully.

My concern is actually based on threads I've read here from reputable members stating that wr should be extremely careful with pressures while water pumping, where 2hg and 3hg are quite high for the new user and match 5hg+ of air pressure. To put it in less words, I just want to approach this in the safest manner possible, with as little edema as possible and not break my penis.

So, if someone can confirm that the electronic gauges provided by leluv or even Bd's market match the hoses, then I'm set. I don't mind buying it off of you also if you include it in the market. Idk if I am allowed to leave links from other markets tho, so I won't.

Having an electronic/auto vacuum system is truly unpredictable. If you can reliabilty, and hopefully be able to verify that there is a safety system to prevent it goes past a certain vaccum pressure at any given point, then the MityVac cylinder is perfectly fine. This is me bringing my experience of cylinder failures due to abnormal vacuum pressure from automated vacuum systems.

By the way, you definitely want to have a vacuum system goes past 5inHg. 5inHg is just a starting point. Upper safety level is 10inHg. 15inHg is considered as reaching unsafe level, but for some, it's a miracle pressure. Most of us, stay far away from that pressure for now.


Most automated built in cylinders pressure are very low end in terms of perforance. The built in system has a snap-on vacuum valves that is not fully compatible with the MityVac cylinder. However, is see some modified the mini pump systems to match. The cylinder may be too large for the mini pumps to effectively pull all the air out. Most who use the automated system use a mid to high end vacuum pumps, powered by large battery pack or plugged directly into the wall socket. LeLuv is way too underpowered by a 3.7V pump motor.


I'm always placing safety at the forefront of PE. Without safety first, we have broken penises left and right.

To provide clarification, internal pressure for an average erection is between 3.5inHg and 4.5inHg. This is why we want an external vacuum pressure to mirror the internal pressure. When we pump, we need to raise the internal pressure to equalize the vacuum pressure. You can feel where you are during the pumping where your internal pressure is at. Let's say during pumping, your penis is fully erected and your vacuum pressure is around 3inHg, if your glans feels comfortable without any expansion, that is your internal pressure. The moment you start feeling your glans starts to have a dull achy feeling while fully erected under pressure, you are reaching and passing your natural internal pressure. This is where you start logging constantly. Pressure increase should not be done at 0.5inHg every 2 weeks. Sometimes longer. I like to increase 0.5inHg every 3 to 4 weeks, and when I'm dead certain that my glans is ready for the steady increase.


The connected valve that the mini pumps over is a quick disconnection I165T model, where as the one on the MityVac and most manual pumps are standard 1/4in or 6mm threaded quick disconnector system. If you're talking about the LeLuv iPump, then yes, they are using a male-female 1/4in pump system. You can even remove the hose and put the hose over the MityVac cylinder's 1/4in barb as an aftermarket retrofit.

Thank you for the detailed response I really appreciate it. Just curious, you say you increase 0.5hg every 3-4 weeks. How can you successfully increase such a small range with a manual gauge?

kakokako123 said:

I mean, in every video online that I see a manual gauge used, a squeeze shoots up 3-5hg.

Forgive my possible ignorance but can we "lightly squeeze" the handle and get "small" hg increases of 0.5hg? Because if that's the case, screw automatic gauges. But if that's not the case, it will create problems for me as a new user, that's my concern. Trust me, this isn't a money problem, nor am I wasting time. But I hate returns and thus I do want to know "for sure" if the manual gauge can do such small increases in hg with light squeezes.

1. Controllable pressure that you can start and stop immediately.
2. Pressure release within a second to prevent sudden damages. It only takes a few seconds to destroy your penis. Some experienced this. Brothers reported in about how fast damages can occur within 10 seconds. A built in safety measure is critical.
3. Pressure upper limit to prevent the penis from suffering accidental pressure overload. Safety growth starts at 5inHg. Safety upper bound is 10inHg. Manual pumps cannot reach 10inHg without your work. Automated pump can go past 10inHg in 10 seconds. Most cheaper models don't have emergency pressure release valve.
4. High pressure cylinder rated. Most cheap acrylic cylinders are rated at 20inHg and less. MityVac cylinder rated at 50inHg before failure. This is based on 5 years old data. @DLD may have newer data based on the latest manufacturer's specs. When pumping, you always want your penis to be in a cylinder tha is rated at least 5 times the pressure of where you want to be. If you are uncertain, don't go there. I have a Bathmate HydroXtreme, and those of us who have them, we tested and noted they started to fail at 25inHg. I left mine in the closet until I need to use the 2.65in girth expansion. Otherwise, I use the MityVac system only.
5. Valve security is required. The quick connectors for the valve needed to be a high quality, even if it's made in China. Most cheap automated pump, or even manual pumps, use cheap silicone and rubber parts. A little heat and chemicals in the water will ruin the parts. Good rubber and plastic costs a bit more upfront, but last much longer with a bit of love and care.

This is all depending on the pump system you have. I have a manual pump system for just that reason. MityVac trigger pump doesn't make the air pressure goes up by 2 to 3 inHg per pump. I switch out all my pump to have 1.5inHg large display, where the vacuum pressure ranges from 0 to -20inHg max. Most guages goes into the -30 and -50. There's no reason to go that high. -15 is more than sufficient. The MityVac trigger pump has a rating of 0.7inHg per full trigger pull when all air volume is empty at static pressure at 0inHg. So, half to 3/4 pull of the trigger will bring the static air pressure to negative air pressure at 0.5inHg. With the larger gauges, I can literally see a 0.15inHg increase of vacuum pressure tick marks. At worst, you see 0.5inHg tick marks. Or, you can always measure based on the rise where the indicator stem is through visual measurement.


When you have 3 to 5inHg rise like that, the trigger pump/power pump is designed for something else and not the penis. They probably use a high air bleed system meant for pneumatic testing, such as gas vacating for large systems and engines. MoS Shop selected the MityVac trigger system to minimize the explosive negative pressure.


Automatic gauges are under monitored. If you look at the built in gauges error rates, be digitial or manual, you'll see an +/- 2 to 5%. In an automated system, when the built in gauge flags a leak, the pump continues to turn on. In most scenario, the leak may just be around the gauge and not in the sealed area of the penis. Because of this, the pressure shot straight up in the penis cylinder while there's a false measurement at the gauge end. As PE-ers, we stick with manual because we can control the needed air vacuum needs. Quite a few hate the ideas of having to constantly pump using their hands as they would like to free their hands up for other things. In reality, a good sealed system doesn't requite you to have your hands on the pump. It should maintain the pressure at all time. If there's a leak, something is not set up correctly.

Your penis is important as a man. Trust not the automated system unless you are dead sure there are at least 3 layers of protection built in. Bathmate and MityVac systems have at least 3 and at the highest 5. Always look for:

1. Controllable pressure that you can start and stop immediately.
2. Pressure release within a second to prevent sudden damages. It only takes a few seconds to destroy your penis. Some experienced this. Brothers reported in about how fast damages can occur within 10 seconds. A built in safety measure is critical.
3. Pressure upper limit to prevent the penis from suffering accidental pressure overload. Safety growth starts at 5inHg. Safety upper bound is 10inHg. Manual pumps cannot reach 10inHg without your work. Automated pump can go past 10inHg in 10 seconds. Most cheaper models don't have emergency pressure release valve.
4. High pressure cylinder rated. Most cheap acrylic cylinders are rated at 20inHg and less. MityVac cylinder rated at 50inHg before failure. This is based on 5 years old data. @DLD may have newer data based on the latest manufacturer's specs.

Hope this helps.
