Is the Brass Hydrant Valve with STORZ Connection (Aluminium or Brass) compatible with standard 1"–2.5" fire hoses and able to withstand 16 bar working pressure?

Yes. The Brass Hydrant Valve with STORZ Connection (Aluminium or Brass) is compatible with standard fire hoses using STORZ couplings in sizes from 1" to 2.1/2" (1"–2.5"), and its external thread connection allows versatile installation with common systems. It is designed to withstand a working pressure of up to 16 bar, providing a secure, leak-free connection via its robust aluminum or brass coupling and white NBR seal, making it suitable for residential, industrial, and other professional fire protection applications.

Can the Brass Hydrant Valve with STORZ Connection (Aluminium or Brass) be used in both indoor hydrant cabinets and outdoor riser systems without additional protective fittings?

Yes. The Brass Hydrant Valve with STORZ Connection (Aluminium or Brass) is specified for use in fire hydrant cabinets and compatible systems; its durable aluminium or brass coupling, NBR seal and external thread sizes (1"–2.5") support typical indoor hydrant cabinet installations. For outdoor riser systems the valve’s materials and 16 bar working pressure indicate it can perform reliably; however, outdoor exposure to weather, UV, freezing temperatures, corrosive environments or mechanical impact can shorten service life if the valve is left unprotected. Practical guidance: - Indoor hydrant cabinets: can be used without additional protective fittings. - Outdoor risers: can be used but it is recommended to protect against weather and mechanical damage (enclosures, frost protection, corrosion-resistant coatings or covers) where environmental conditions are harsh or frost is possible. If installation must meet specific local codes or warranty terms, verify manufacturer recommendations and applicable standards before final installation.
