You asked for it!.... Introducing the NEW

BullMaster Magnum

Contoured Acrylic Multi-stage Shaping Cylinder

The famous BullMaster now has an even bigger brother!

It's not for everyone. We had many Bull pumpers who were filling the standard cylinder, and asking for even more space. We created new tooling, and now it's here, in stock, ready today. If you have the package that needs it, your cylinder is here! How big a package do you need- or should we ask- how big a package do you want??

In the picture below, you can compare the sizes of the pocket extrusions of the Magnum to the standard BullMaster.

HERE'S SOME FEEDBACK FROM NEW MAGNUM USERS:

DZ: "Just know that I truly regret not having made this purchase long-ago! I've been pumping off/on over the past 18 years and am so impressed with the design of the BullMaster Magnum. The results in one hour are similar to 2-3 hrs prior in flared cylinder and/or Monster Tube."

GA: "To Dan & the crew from pumptoys: my Bull Magnum with silicon seal arrived on the 8th of August. What a GREAT unit! The soft silicon seal makes for great comfort. I love the way the pockets pull the balls down & wide apart while the penis is kept round! Take a look at the attached pictures from my first Magnum pump session!"

Features of the BullMaster Magnum:

  • Formed from premium Cast Acrylic tube by our own custom process!
  • Clear domed cap made from cast 3/8" thermal-formed acrylic!
  • Laser engraved BullMaster Magnum Logo!
  • Multi-stage, smooth transitions throughout.
  • Much larger tear-drop testicle pockets pull you down, fill you up!
  • Longer Tapered penis pocket keeps you round.
  • Comes with industry-standard quick disconnect coupler body installed.
  • Coupler is offset to the top edge for easy access and wet pumping!
  • Includes PumpToys extra-soft STJS Silicone Precision Seal! (highly recommended for extra seal stretch range).
  • PumpToys standard STJ Precision Seal (Vinyl) is available optionally at lower cost.
  • BullMaster Magnums are finished in custom lengths to fit you personally! NO extra cost!

Dimensions:

  • Primary tube nominal is 4" ID
  • Contour area increases dimensions to 6-1/2" wide X 5" high at contour maximums.
  • Exit/entry diameter is nominal 4", which reduces to a 2-3/4" working diameter neck at the seal.
  • Maximum internal length total: 11-1/4" cap to hard rim, not including seal.
  • Maximum internal length to end of penis contour: 9-1/2" not including seal.
  • Maximum internal length to end of ball contour: 9" not including seal.

The seal adds about 1/2" to the length. This is an Even bigger cylinder- designed for advanced pumpers. The internal perimeter dimension in the contours is about 18"!


The Magnum is available in 5 lengths: 7.5", 8", 8.5", 9" and 9.5". Order sizes shown are based on the internal "Length from hard rim to end of penis contour".
Ideal length range is 1" to 1-1/2" over your erect length. You should also look at the relationship for the scrotum bulge: The center of Ball Pocket bulge will be 2-1/2" less than the tube's order size. If you order a 7-1/2" tube, the center of the ball pockets will be 5" from the hard rim of the cylinder. If you order a 9" tube, the center will be at 6-1/2". We recommend you look at the BMC Fitting Guide to help you select a size and compare with the standard version.

5 Best cylinders in the market

I’m one of the lucky souls that possesses one of this bad boys. It’ll have you feeling huge in no time. While it can be a little tricky to get on the first couple of times, you learn how to use it pretty easily. Once these are back in stock, invest in one! You won’t regret it! The one thing I would warn about is getting the first measurement correct. I had to send my back to have it cut down just slightly to have a better pumping experience. ... read more.
