Overview:
The FKM 75 O-Ring (3.1mm cross-section, 45mm internal diameter) is a precision-engineered elastomeric seal, purpose-built for the small rotary valve assemblies found in Technopack’s range of high-viscosity piston fillers—including the E-FP-100-DX, E-FP-300-DX, E-FP-500-DX, and E-FP-1000-DX models. This robust seal ensures optimal valve function, maintaining directional flow control and leak prevention during the fill cycle of viscous and semi-viscous products.

Key Features:

• Premium Fluorocarbon (FKM) Construction:
  Manufactured using high-performance FKM rubber with a 75 Shore A hardness rating, this O-ring provides exceptional resistance to chemicals, oils, fuels, and high temperatures. Suitable for use in processing complex or reactive formulations.

• Tailored for Rotary Sealing Applications:
  Specifically dimensioned to fit the small rotary valve component, the 3.1mm CS x 45mm ID profile ensures a secure, dynamic seal during valve rotation, preventing cross-contamination and ensuring accurate product flow regulation.

• High-Temperature & Chemical Resilience:
  Operates reliably in demanding conditions, with a working temperature range from -20°C to +200°C. Compatible with a wide spectrum of product chemistries including food-grade pastes, cosmetic gels, industrial greases, and more.

• Long Service Life:
  Excellent resistance to compression set and mechanical wear enhances performance longevity and minimizes the frequency of seal replacement, making it a cost-effective solution for continuous production environments.

Applications:

• Filling Equipment Compatibility:

  • E-FP-100-DX High Viscosity Piston Filler

  • E-FP-300-DX High Viscosity Piston Filler

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

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

• Rotary Valve Functionality:

  • Installed within the small rotary valve assembly, this O-ring ensures precise flow redirection during suction and discharge phases of the filling cycle.

  • Maintains a consistent seal under variable pressure conditions and dynamic rotary motion, critical for high-viscosity product handling.

• Ideal for Use In:

  • Food processing (e.g., thick sauces, nut spreads)

  • Personal care and cosmetics (e.g., heavy creams, pastes)

  • Chemical and industrial products (e.g., adhesives, lubricants)
