FKM 75 - O-Ring 5mm CS x 48mm ID

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-DX high 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.

• Ideal Product Types:

  • Food applications: Thick sauces, syrups, fillings

  • Cosmetics: Creams, butters, balms

  • Industrial: Greases, silicone compounds, epoxy bases
