Why Genius™ PosiLok™ Pistons

Genius® PosiLok™ Pistons

1. PosiLok™ industrial thread locks the piston to the drive rod guaranteeing no slippage during dispensing — no pressure loss.

2. Increased interference fit completely seals the chamber — no pressure loss.

3. Thick, maximum-strength wall for high-pressure dispensing — no pressure loss, for safety and consistent repeatability.

4. No interlocking connection between the piston and the drive rod. Piston slips during the dispense, creating pressure loss.

5. Light interference fit does not seal the chamber, thin wall flexes under pressure, allowing fluid to flow by — creating a pressure loss and potentially damaging the dispense gun.

6. Thin wall collapses under pressure, creating pressure loss.

7. Pressure from the lead screw on the center collapse
