Overview: The FKM 75 O-Ring (5mm cross-section, 48mm internal diameter) is a precision-molded dynamic sealing component developed for use in the piston head of the Technopack E-FP-300-DXhigh viscosity piston filler. This O-ring plays a critical role in maintaining airtight sealing during the suction and dispensing phases, ensuring consistent volumetric accuracy and preventing product loss, especially in applications handling dense, high-viscosity materials.
Key Features:
Premium FKM (Fluorocarbon Rubber) Material: Composed of high-quality FKM elastomer rated at 75 Shore A hardness, this O-ring is highly resistant to oils, fuels, solvents, and aggressive chemicals. It is ideal for use in sanitary and industrial processes involving complex formulations or reactive compounds.
Dynamic Sealing for Piston Motion: Specifically dimensioned for sealing the interface between the piston and cylinder wall in the E-FP-300-DX, this O-ring ensures smooth piston movement while preventing internal leakage, even under high back pressure conditions.
High Temperature & Chemical Resistance: Offers excellent thermal stability from -20°C to +200°C, making it suitable for processes involving heated materials or steam-assisted cleaning. Maintains sealing integrity when exposed to caustics, acids, or organic formulations.
Low Compression Set: Designed for long-term service under repetitive compressive forces, this O-ring resists deformation and wear, resulting in reduced downtime and fewer seal replacements during equipment maintenance cycles.
Applications:
Filler Compatibility:
Custom-fit for the piston assembly of the E-FP-300-DX High Viscosity Piston Filler
Primary Functions:
Creates a durable, leak-free seal within the piston housing to allow accurate suction and discharge of viscous products.
Prevents bypass or backflow during stroke cycles, preserving batch integrity and dose uniformity.
