Application Fit & Sizing Matrix

Operational Limits
pressure: Up to 150 psi (static), 100 psi (dynamic)
temperature: -60°C to +230°C
compression set: ≤25% after 22 hours at 175°C
chemical resistance: Resistant to most oils, fuels, and mild chemicals
Media Compatibility
✓ Hydraulic fluids and oils ✓ Potable water systems ✓ Food-grade applications (FDA compliant grades)
Unsuitable: Concentrated acids/bases or strong oxidizing agents
Sizing Data Required
  • Gland dimensions (depth, width, clearance)
  • Application temperature profile (min/max/continuous)
  • Media type and concentration

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Compression set
Cause: Prolonged exposure to high temperatures or pressures beyond material specifications, leading to permanent deformation and loss of sealing elasticity.
Chemical degradation
Cause: Incompatibility with process fluids, cleaning agents, or environmental contaminants, causing swelling, hardening, or surface cracking of the silicone polymer.
Maintenance Indicators
  • Visible extrusion or 'blow-out' of gasket material beyond flange edges during operation
  • Audible hissing or detection of process fluid leaks at flange connections during pressure testing
Engineering Tips
  • Implement controlled torque procedures during installation using calibrated tools to ensure uniform compression without exceeding material limits
  • Establish regular inspection intervals using borescopes or flange gap measurements to monitor compression set before catastrophic failure occurs

Compliance & Manufacturing Standards

Reference Standards
ISO 3601-1:2012 (Fluid power systems - O-rings) ASTM D2000 (Standard Classification System for Rubber Products) CE Marking (EU Regulation 2017/745 for Medical Devices if applicable)
Manufacturing Precision
  • Thickness: +/-0.05mm
  • Surface Flatness: 0.1mm over 100mm length
Quality Inspection
