Overview:
The FKM 75 O-Ring (3.5mm cross-section, 45mm internal diameter) is a high-performance sealing component specifically engineered for the rotary valve assemblies of Technopack’s E-FP-100-DX and E-FP-300-DX high viscosity piston fillers. Designed for dynamic sealing applications, this O-ring ensures leak-proof, smooth rotary valve operation under demanding production conditions involving thick, semi-solid, and chemically aggressive materials.

Key Features:

• Premium-Grade FKM Material:
  Constructed from durable fluorocarbon rubber (FKM) with a 75 Shore A hardness, this O-ring delivers exceptional resistance to oils, fuels, chemicals, and elevated temperatures. It is ideal for filling applications involving aggressive formulations or sanitary processing.

• Engineered for Rotary Motion Sealing:
  Designed for rotating valve components, the 3.5mm CS x 45mm ID dimensions provide a precision fit within the valve housing—ensuring a dependable seal that accommodates movement while preventing leakage and cross-contamination.

• Temperature & Pressure Resilience:
  Operates within a wide temperature range of -20°C to +200°C, maintaining sealing integrity under dynamic mechanical loads and varying thermal conditions common in piston-filler operations.

• Excellent Compression Set Resistance:
  With low permanent deformation under repeated compression, this O-ring supports longer service life and minimal maintenance requirements—critical in high-throughput filling environments.

Applications:

• Equipment Compatibility:

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

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

• Functional Use:

  • Positioned within the rotary valve mechanism, this O-ring enables smooth directional flow switching during the suction and discharge cycles.

  • Ensures accurate and leak-free operation in handling high-viscosity products such as creams, gels, pastes, sauces, or adhesives.

• Ideal for Use In:

  • Food processing: Thick condiments, syrups, and fillings

  • Cosmetic production: Lotions, balms, and emulsions

  • Industrial applications: Greases, sealants, and silicone-based compounds
