Techcon’s 700 Series air-powered pistons are designed to sit directly on the material to distribute pressure evenly, ensuring consistent dispensing even with high-viscosity fluids. These precision components are manufactured from durable polyethylene (PE) and are engineered to eliminate air entrapment and material waste.

Piston Selection by Application

• Easy Flow (Blue): Designed to require less pressure for dispensing while actively preventing air from becoming entrapped during the process.
• Wiper (White): Features a tight-fit design that provides a complete seal, ideal for low-viscosity fluids to ensure a clean wipe of the syringe walls.
• Straight Wall (Red): A loose-fit design specifically for high-viscosity materials, effectively preventing “stringing” and “bouncing” (pressure kickback).
• High Interference (Green): Provides an extra-tight fit for specialized applications (available for 30-55 cc barrels) to ensure maximum sealing integrity under specific industrial conditions.
