The Hydrant Valve Disk Washer Rubber (85 mm) is a heavy-duty sealing gasket designed for use in fire hydrant valves to ensure a secure, leak-free connection. It sits between the valve seat and the hydrant mechanism, preventing water leakage when the valve is closed. Made from high-performance rubber, this washer ensures smooth operation and long-term durability in demanding conditions.
Key Specifications:
- Material:
- EPDM (Ethylene Propylene Diene Monomer) – Excellent weather, ozone, and chemical resistance.
- Nitrile (NBR) – Superior oil and fuel resistance.
- SBR (Styrene Butadiene Rubber) – Good abrasion resistance.
- Size:
- Inner Diameter (ID): 85 mm (standard, can vary slightly based on design).
- Outer Diameter (OD): Typically 95-100 mm (depends on valve model).
- Thickness: 5-10 mm (varies by application).
- Temperature Range:
- -30°C to +120°C (EPDM handles extreme temperatures better).
- Pressure Rating:
- Up to 16 bar (232 PSI) – Suitable for high-pressure hydrant systems.
- Color:
- Usually black or red for easy identification.
- Standards & Compliance:
- ISO 9001 (Quality Management)
- NFPA 1963 (Fire Hose Connections)
- AWWA (American Water Works Association) Standards
- BS 750 (British Fire Hydrant Standards)
Applications:
✔ Fire hydrant valves (underground & above-ground)
✔ Water supply systems
✔ Industrial hydrant connections
✔ Municipal firefighting equipment
Advantages:
✅ Excellent Sealing – Prevents leaks in closed valve positions.
✅ Durable & Long-Lasting – Resists wear, cracking, and deformation.
✅ Chemical & UV Resistant – Suitable for outdoor and harsh environments.
✅ Easy to Install – Fits securely into valve assemblies.
Maintenance & Replacement:
- Inspect periodically for cracks, hardening, or deformation.
- Replace if signs of wear or damage are present to ensure proper sealing.
