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)
