Cap and Chain 2.5" Brass Cap for Fire Protection System

The Viking Cap and Chain 2.5" Brass Cap is a heavy-duty closure component designed to protect fire hydrants, hose valves, and standpipe connections within commercial fire protection systems. It installs directly onto 2.5-inch threaded outlets, establishing a tight, leak-resistant seal that safeguards vital infrastructure against internal debris intrusion, foreign object damage, and environmental corrosion.

This component satisfies stringent commercial life safety mandates and is manufactured in accordance with National Fire Protection Association (NFPA) standards. Utilizing this certified hardware ensures compliance during AHJ inspections and supports operational reliability across wet, dry, and standpipe fire suppression networks.

• Material Construction: Forged from premium B124 brass alloy, delivering high tensile strength and superior corrosion resistance in harsh indoor or outdoor environments.
• Sizing: Engineered precisely for standard 2.5-inch fire hydrant and valve connections, ensuring a secure, tight fit that preserves system integrity.
• Integrated Retention Chain: Features a securely attached brass chain to prevent loss or misplacement of the cap during system operations, routine maintenance, or fire flow testing.
• System Protection: Blocks dirt, insects, and moisture from entering idle lines, eliminating common causes of valve failure and reducing long-term maintenance downtime.

Contractors and facility managers must verify all local Authority Having Jurisdiction (AHJ) requirements and cross-reference system design criteria before final installation. Documentation: Download Manufacturer Technical Data & Cut Sheet (PDF)
