The Hydrant Valve Coupling Rubber Washer (63 mm) is a critical sealing component used in fire hydrant systems to ensure a watertight connection between hydrant valves and hoses or couplings. Made from high-quality rubber, this washer prevents leaks, maintains pressure, and ensures efficient water flow during firefighting operations.

Key Features:

• Material: Durable, high-grade rubber (EPDM/Nitrile/SBR) for excellent water resistance and longevity.
• Size: 63 mm (inner diameter) – designed to fit standard hydrant couplings.
• Thickness: Typically 5-8 mm (varies based on design requirements).
• Color: Usually red or black for easy identification.
• Temperature Resistance: -30°C to +120°C (varies by material).
• Pressure Rating: Withstands high water pressure (up to 16 bar or as per standards).
• Compliance: Meets ISO, NFPA, BS, or other relevant fire safety standards.

Applications:

• Fire hydrant systems
• Fire hose couplings
• Standpipe connections
• Industrial water supply systems

Advantages:

✔ Leak-proof seal – Ensures tight connection.
✔ Chemical & Weather Resistant – Suitable for harsh environments.
✔ Long Service Life – Resistant to wear and deformation.
✔ Easy to Install – Fits securely into coupling grooves.

Standards & Certifications:

• ISO 9001 (Quality Assurance)
• NFPA 1963 (Fire Hose Connections)
• BS 750 (UK Fire Hydrant Standards)
