Does the STORZ Firefighter Union Wrench, Size BC, Durable Malleable Cast Iron fit both B (75) and C (52) STORZ hose couplings?

Yes. The STORZ Firefighter Union Wrench, Size BC, Durable Malleable Cast Iron is designed specifically for STORZ hose couplings in both sizes B (75) and C (52), providing a precise fit and secure connection for each. Its durable ductile iron construction and ergonomic design ensure reliable performance and firm grip across both coupling sizes, making it suitable for professional firefighting and rescue operations.

Is the STORZ Firefighter Union Wrench, Size BC, Durable Malleable Cast Iron compatible with other common fire coupling standards or adapters?

STORZ Firefighter Union Wrench, Size BC, Durable Malleable Cast Iron Format is specifically designed for STORZ fire hose couplings in sizes B (75) and C (52). It provides a precise fit and secure engagement with those STORZ standards, so compatibility with other coupling systems is not inherent. STORZ couplings are a genderless, quarter‑turn standard; adapters exist to mate STORZ to other common fire coupling types (e.g., NH/ NHT, BSP, or other threaded/flanged connectors). The wrench itself will work reliably on STORZ couplings and on any adapter or fitting that preserves the STORZ lug profile and dimensions. It will not properly engage non‑STORZ couplings unless an appropriate adapter converts them to the STORZ lug geometry and size.
