Is the STORZ Brass Firefighter Swivel Coupling with BSP Female Thread compatible with standard 1.5" and 2.5" firefighting hoses?

STORZ Brass Firefighter Swivel Coupling with BSP Female Thread is designed as a universal Storz swivel with an internal BSP thread and a symmetrical (Storz) connection. Compatibility with standard firefighting hoses depends on two things: (1) the Storz coupling size (the coupling’s nominal diameter) and (2) whether the hose or adapter uses a matching Storz female/male profile. Common firefighting Storz sizes include DN25 (1"), DN40 (1.5"), DN65 (2.5") etc. If the STORZ Brass Firefighter Swivel Coupling with BSP Female Thread is the DN40 variant it will pair with standard 1.5" Storz hoses; if it is the DN65 variant it will pair with standard 2.5" Storz hoses. The BSP internal thread allows attachment to threaded pipes or fittings of the matching BSP size, not directly to non‑Storz threaded hose ends. Conclusion: The coupling can be compatible with standard 1.5" and 2.5" firefighting hoses only if you select the matching Storz size (DN40 for 1.5", DN65 for 2.5") — otherwise it will not mate. Ensure the coupling’s nominal Storz size and BSP thread size match your hose or adapter specifications.

Can the STORZ Brass Firefighter Swivel Coupling with BSP Female Thread be used with potable water systems and food-grade applications?

The STORZ Brass Firefighter Swivel Coupling with BSP Female Thread can be used in potable water systems and food-grade applications with important reservations. Its high-quality brass body and robust black NBR rubber seal provide durability, tightness and resistance to wear, and the product description explicitly lists food processing among suitable applications, indicating suitability for certain food- and water-related uses. However, suitability for potable water and food-grade certification depends on specific material certifications (e.g., WRAS, ACS, NSF/ANSI 61, or EU food-contact approvals) and absence of lead or other contaminants in the brass alloy. Before using this coupling for drinking water or direct food contact, verify with the manufacturer or supplier that: - The brass alloy meets relevant potable-water and food-contact standards for your region. - The NBR seal is approved for potable water/food use. - Any required certification documentation is provided. If certified, the STORZ Brass Firefighter Swivel Coupling with BSP Female Thread is appropriate; if not, choose a certified alternative.
