Overview:
The FKM 75 O-Ring (cross-section 3.5mm, internal diameter 60mm) is a heavy-duty, precision-engineered sealing ring tailored for the large rotary valve system of Technopack's E-FP-500-DX and E-FP-1000-DX piston fillers. Built to maintain a tight, chemically resistant seal in high-viscosity product environments, this O-ring ensures reliable, long-term performance in demanding production applications.

Key Features:

• Durable Fluorocarbon (FKM) Elastomer:
  Crafted from high-grade FKM rubber with a 75 Shore A hardness rating, this O-ring exhibits excellent resistance to high temperatures, aggressive media, and chemical degradation. Ideal for high-viscosity product transfer systems where aggressive formulations are common.

• Precision Fit for Rotary Motion:
  Designed to seal the rotating surfaces of the large valve mechanism, the 3.5mm CS and 60mm ID dimensions provide a snug fit that prevents product leakage while allowing for consistent rotary motion and pressure regulation.

• High Temperature & Chemical Resistance:
  Operates effectively in temperature ranges from -20°C to +200°C and withstands exposure to oils, solvents, and chemical agents—making it suitable for a wide range of viscous materials including pastes, gels, and semi-solids.

• Enhanced Compression Set Resistance:
  The O-ring maintains its integrity and elasticity under repeated compression cycles, reducing the frequency of seal replacement and improving uptime during high-volume production.

Applications:

• Filler Compatibility:

  • E-FP-500-DX High Viscosity Piston Filler

  • E-FP-1000-DX High Viscosity Piston Filler

• Rotary Valve Use Case:

  • Serves as the primary seal for the large rotary valve chamber, regulating the flow direction of thick fluids during the intake and discharge phases of the filling process.

  • Ensures a leak-free seal even under dynamic mechanical movement and high back-pressure conditions typical in piston-based systems.

• Industries Served:

  • Food and beverage (e.g., sauces, nut butters)

  • Cosmetic and personal care (e.g., creams, pastes)

  • Chemical and industrial (e.g., adhesives, sealants)
