2-1/2" Plastic Cap with Chain For ABS NST FDC Connection

The Viking 2-1/2" Plastic Cap with Chain secures ABS NST fire hose and Fire Department Connection (FDC) assemblies across municipal, industrial, and commercial fire suppression systems. This component installs directly onto 2-1/2" National Standard Thread connections to maintain tight seal integrity, preventing moisture and debris ingress that can compromise operational readiness. The bright red finish ensures rapid visual identification during routine inspections or emergency deployments.

This accessory fulfills code-mandated system maintenance requirements outlined in applicable NFPA standards, supporting regulatory compliance and inspection readiness for facility managers and trade contractors. The integrated metal chain permanently anchors the cap to the connection point to eliminate misplacement during high-pressure response operations.
