Dry Ryser Inlet
The Dry Riser Inlet (Breeching Inlet) is a vital component of fire protection systems used in multi-storey buildings to supply water to the dry riser pipeline during firefighting operations. It allows firefighters to connect hoses from fire engines and pump water into the building’s fire safety system. Manufactured from high-quality ductile iron, gun metal, or stainless steel, the dry riser inlet is designed for durability, corrosion resistance, and reliable performance. Available in 2-way, 3-way, and 4-way inlet configurations, it complies with IS:904 standards and is ideal for commercial, industrial, and residential fire safety installations.
