PTFE Flat Washer Gasket – ID 6mm × OD 100mm, 2mm Thick | High Temp, Chemical Resistant for Flange Sealing

PTFE Flat Washer – High-Temperature, Corrosion-Resistant Gasket for Flange Sealing

Exceptional Performance for Demanding Industrial Applications

Discover the ultimate sealing solution with our precision-engineered PTFE flat washer. Designed for use in high-pressure, corrosive, and temperature-sensitive environments, this gasket combines strength, chemical resistance, and electrical insulation. Whether you work in chemical processing, aerospace, electronics, or food machinery, this PTFE gasket offers reliability that outlasts the toughest conditions.

Key Features That Set Us Apart

• High Temperature Resistance
  Withstands extreme temperatures from -200°C to +250°C (-328°F to 482°F) without deformation or breakdown—ideal for fluctuating industrial environments.

• Superior Corrosion Protection
  Constructed from virgin PTFE (Teflon), this washer resists strong acids, alkalis, solvents, and moisture, making it perfect for chemical systems and outdoor use.

• Reliable Electrical Insulation
  Non-conductive material ensures safety and performance in electronics and power distribution systems.

• Anti-Aging and Weatherproof
  Excellent dimensional stability, even under UV, ozone, or long-term pressure, minimizing replacement cycles.

• Consistent Precision Machining
  Each washer is CNC cut with exact specifications to ensure a perfect fit and tight seal for flange joints and machine parts.

Available Sizes – Metric & Inch Friendly

Choose from over 100+ size combinations, each with a consistent 2mm thickness. All washers are labeled with inner diameter (ID) × outer diameter (OD), available in:

• 🔩 Metric Sizes: From 6mm ID × 12mm OD to 90mm ID × 115mm OD

• 📏 Imperial Reference: Example – 6mm ID × 12mm OD ≈ 0.24″ × 0.47″
