Learn how to fit and align the left hexagonal piston on your Sizegenetics traction device. Follow these steps to avoid misalignment and keep traction smooth.

Quick answer

To fit the left hexagonal piston correctly, remove the old part, clean the threads, and hand-thread the new piston until snug. Then check that the hex sits flush and the rod moves without binding before you apply tension.

Why the left side needs its own approach

The left piston is a dedicated spare part shaped to fit the left side of the device. It is not a universal piston, so using it on the right side or forcing it into a different housing can damage the threads or cause uneven traction.

Because the hexagonal shape locks into a matching recess, alignment matters more than torque. If the hex does not seat cleanly, stop and recheck the seating rather than tightening further.

When replacement is the right call

Replace the left piston if you notice a worn hex, stripped threads, or a piston that no longer holds adjustment. A loose or damaged piston can make tension inconsistent and affect comfort during use.

If the rest of the device is in good condition, a single spare part is usually enough. Inspect the opposite side and the rods at the same time so you do not overlook a related wear point.

Step-by-step fitting and alignment

  1. Remove the old left piston: Unscrew the old piston fully and set it aside. Do not pry it out, as that can damage the housing. Check the old piston for stripped threads; if present, inspect the housing before installing the new part.
  2. Clean the threads and recess: Wipe the threads and the hexagonal recess with a dry cloth to remove debris or old lubricant. A clean recess lets you feel whether the new piston seats properly.
  3. Hand-thread the new piston: Start threading the hexagonal piston left by hand, turning it counterclockwise until it catches. Do not use tools at this stage. If it does not catch easily, back it out and restart to avoid cross-threading.
  4. Seat the hex flush: Turn the piston until the hexagonal head sits flush against the housing. Stop when it is snug; do not overtighten. A visible gap means the hex is not seated; recheck alignment before applying tension.
  5. Test movement and alignment: Move the rod through its range and confirm the piston stays aligned without wobble or binding. Any binding or uneven resistance is a sign to loosen and reseat the piston.

Product facts

  • Hexagonal piston left: This is a single spare hexagonal piston designed for the left side of Sizegenetics penile traction devices. Buying the correct side-specific part avoids fit issues and keeps the device functioning as intended.
