Hydromax X40 Xtreme Penis Pump

Bathmate Hydromax X40 Xtreme Penis Pump Review

We were kindly sent the Hydromax X40 Xtreme Penis Pump from Bathmate for an honest review and I am a huge fan of Bathmate. I have previously had the pleasure of testing and reviewing some of their products, including the Hydromax X30, the Hydromax X40 and the newly released Bathmate Hydrodouche and those experiences have all been positive overall. So positive in fact, that I did not believe it could get much better, until I ran into Bathmate at a recent trade show and noticed they had released a new pump, this one with a hand pump attachment. As soon as I saw this in action, I was hooked. I couldn’t wait to give this product a test drive and find out how it compared to previous Bathmate pumps.

Product Information:

The Hydromax X40 Xtreme pump comes as part of a set, containing everything you need to begin (and continue) a penis pumping program. The pump and other contents come in a discreet and very solid carry case, which can be used for long term storage. Included in this set are the following items:

The X40 Xtreme Penis Pump:

The X40 Xtreme contains the largest chamber in the Xtreme collection and is designed for guys who measure approximately 7 inches or more in length or 5 inches or more in girth. If you are smaller than this, you could consider the X30 Xtreme, but you can still effectively use the X40 Xtreme if you are smaller (my partner is) and it is unlikely that you will outgrow it, which means never having to upgrade.

The total length of the X40 Xtreme is 13.5 inches. This includes the uncompressed gaiter and the valve. The chamber and compressed gaiter together, measure 10.5 inches in length, which is the approximate length this pump will allow you to grow to, before you need to upgrade. The chamber varied between 9.25 inches and 8.25 inches in circumference, depending on where I take the measurement, but I believe it will allow you to swell up to roughly 9 inches in girth. The X40 is clearly a large penis pump and unless you are breaking records already, it should benefit the vast majority of men.

The Hand Pump Attachment:

Unlike most other Bathmate pumps, the new Xtreme pumps come with a hand pump attachment. The detachable hand pump offers variety to users and many more benefits, which I will discuss later (see our experiences). The bulb measures 6.75 inches in circumference, 4 inches in length and comes with a 15.5 inch hose. Just like the rest of the set, is high quality and build to last. The bulb comes with a valve attached, but this valve is designed to simply build a vacuum and allow water/air to pass through the bulb during pumping. The valve on the bulb does not release the vacuum. When this is required, you need to push down on the valve situated on the pump chamber instead.

The Comfort Pad:

Like most Bathmate pumps, the X40 Xtreme comes with a comfort pad, made from a softer (compared to the gaiter itself) rubber material. This pad is designed to slot inside the gaiter, creating a wider surface area and a cushioning effect. The pad is designed to help reduce the discomfort felt when pulling the gaiter into your body during use.

Measuring Gauge:

As part of this set, you get a measuring ruler, which allows you to keep track of your progress as you continue with your pumping program. This ruler measures both length and the width of your penis, so it will allow you to document any improvements in both of those measurements.

Shower Strap:

The shower strap attachment is simply a large strap that allows you to use the pump hands free. You simply attach the strap to the chamber, put the other end around your neck and it will hold the pump in place.

Cleaning Instruments:

Also included in this set is a long handled cleaning sponge, for cleaning the inside of the pump chamber and a high quality towel (face towel size) with embroidered Bathmate logo.

Lubricant and user manual:

You will also find a small bottle of water-based lubricant, which comes in handy when using the pump without water (apply some to the comfort pad before use. It helps create a stronger seal) and an instruction manual packed full of tips and instructions for use.

Our Experience using the Hydromax X40 Xtreme:

The Hydromax X40 Xtreme is an incredibly versatile penis pump. Probably the most versatile we have tried to date, up to and including the Penomet Pump, which comes with interchangeable gaiters. The X40 gives you the option to use it as an air pump, as well as a hydro-pump, but in our experience it was easier to use and more effective overall when used with water. Water seems to help create a stronger vacuum and the warmth helped to relax the blood vessels, allowing him to push that bit further. If you do decide to use the Xtreme as an air pump, I recommend applying some water based lubricant to the comfort pad first, as this helps create a stronger vacuum.

As well as the two options above, you also have the choice over how to use the pump generally. You can use it in the same way as the standard Hydromax X40 and create a vacuum by pulling the pump into your body, essentially compressing and releasing the gaiter to create suction. The difference between the standard X40 and the X40 Xtreme though, is that the Xtreme comes with the hand pump attachment, which you can attach to the valve system at the end of the pumps chamber. You can then create the suction by compressing and squeezing the hand bulb instead.

The hand pump may seem like an additional extra for those who prefer variety and it is, but it is a lot more than that too. My partner commented that using the hand pump, rather than compressing the gaiter manually, reduced the discomfort felt around his pubic area. It also took a lot of the physical effort out of penis pumping, allowing him to lay back and relax during the process. I realised that this may be a huge benefit to those suffering weakness or disability in their arms, hands or wrists.

But I haven’t even mentioned the most thrilling benefit of all yet. The Hand pump allowed my partner to pump his penis further than was possible using the compression method alone. See, the compression method will create roughly 95% of the vacuum possible inside the chamber, but the gaiter is designed to spring back where possible. It is impossible to completely compress this gaiter by manually pulling the device into your body, but the hand pump will literally suck every ounce of water/air out of the chamber, making your pumping sessions 100% effective. As a perfectionist, this excites me.

Of course, as a perfectionist, I did find one minor issue with the hand pump attachment. The connection between the hose and the pump chamber can be extremely flaky initially. The slightest knock will disconnect the hose, so you have to hold it on until you have built up a vacuum. Once the vacuum is created, the hose generally stays in place well. It is also worth noting that you don’t need to use the hose section if you don’t want to. You can attach the hand bulb to the Xtreme directly, if you wished to.

The results:

The Hydromax X40 Xtreme is the third Bathmate penis pump to make it into our collection and I have always been incredibly impressed with the results, but I have to say, the X40 Xtreme impressed me the most. The results are beyond good; they are surprisingly good. We noticed a large increase in both length and girth after removing the pump and those results lasted for roughly one hour, before his penis had almost returned to normal. Just like with previous Bathmate pumps, we discovered the results lasted longer if he stuck to a regular pumping schedule. Bathmate liken the pumping process to working out in the gym and this is an accurate portrayal. The more effort put in, the greater the results you will see. When you stop for a while, things tend to return to normal again. I therefore do not believe that pumping can produce dramatic, permanent effects, but it certainly does produce dramatic short term effects. It also heightened his sensitivity for an hour or so after pumping, which is another fantastic benefit, in my opinion.


As previously mentioned, Bathmate continue to impress me with their male enhancement products, but if someone were to ask me, “What is the best penis pump you have experienced” I would answer without hesitation, “The Hydromax X40 Xtreme”. This penis pump is just so versatile, made to the highest standard and produces the results we desired. The fact that it comes as part of a set, with lots of additional extras, is just the icing on the cake and these little extras helped create a full and rounded experience.

I would definitely recommend the X40 Xtreme to the vast majority of males and unless you have an exceptionally large penis to begin with, I can’t see you needing to upgrade this set. It is perfect for beginners because it is simple to use and unintimidating, but it is also ideal for advanced users who demand perfection, quality and noticeable results.  Yes, it is pricier than the standard Hydromax pumps, but in my opinion it is worth every penny. If money is an issue, I recommend taking a look at the standard X40 pump, but if you can afford to splurge and want the best of the best, I highly recommend the Hydromax X40 Xtreme.
