X4 Labs Closed, Where To Buy Replacement Parts?

The strap from LeLuv is slightly narrower, which may fit with their headpiece, but it leaves some extra room with an X4 headpiece and making it less secure. The strap material is also more pliable than an X4 strap, which may cause them to have a shorter lifespan. X4 straps are firm, then slowly soften with use, so a strap that starts out really soft seems like it won’t last as long.

You could try shimming the straps using the penny trick.

I coincidentally stockpiled the X4 straps before they went out of business. I believe I’m snapping a strap every 200 or so hours. Another trick I learned to lengthen the lifespan of a strap is to leave one side locked in place and only enter and exit from one side. As soon as I see a “nick” on the edge of that strap, I then anchor it down and begin to enter and exit from the other side. Eventually a “nick” will develop on that side too and the strap will snap. However, this technique has doubled the life of my straps. One challenge with this approach was developing my entry method using both the left and right side of the strap, calling for a bit of ambidexterity, but I have been successful to that end.

Can you take a photo of the X4 strap laying flat and provide some size numbers? Length, width and thickness?
I can make a mold and duplicate them.

I can work on getting you some dimensions.

Hi there Baba.. I use the x4 labs as well and used only the comfort strap and foam as well. Once I ran out tho I opted to try a silicone tube and Velcro strap.. And for me it works way better.. I can really get a good stretch.
I started at ab 6.5 in BPEL now I’m at 7 1/8 BPEL..
Seems to work 💪. Good luck.

What silicone tube did you use to replace the X4 memory foam with, and where did you purchase it? I also have the same problem that I’m down to one memory foam thingy from X4. In order to make the memory foam last as long as possible, I substituted it with simple cloth that I cut and wound any my penis several times to act as a cushion. It works, however with cloth, I have way more slippage using the X4 than with memory foam.

Would love to know where other people find good replacements.

This thread seems to have died out but hoping to bring it back.

I’m new here and have been using the X4 Labs extender off and on for several years. Modest gains but that’s my fault for my lack of dedication. I’ve been much more diligent lately but broke my second to last strap.

I’m wondering if anyone has found a comfort strap replacement? I can’t get the Velcro strap to work effectively and I’m now on my last comfort strap.

Thanks for any help
