500 Pack Sprinkler Valve Tamper Seals 20" - Red - Sequentially Numbered

Keep fire sprinkler control valves secured with our heavy-duty sequentially numbered sprinkler valve tamper seals. These pull-tight plastic seals are designed to help maintain valves in the required open position while providing clear visual evidence of unauthorized operation or tampering.

Each seal is marked with a unique 7-digit sequential serial number for easy identification, inspection tracking, and accountability. Once installed, the seal must be broken to remove it or operate the valve, making it a simple and effective tamper-evident solution for fire protection systems.

Ideal for OS&Y valves, butterfly valves, risers, and sectional control valves, these single-use tamper seals are made from durable heavy-duty nylon/plastic for dependable performance in commercial, industrial, and institutional environments.
