To ensure performance in high - pressure emergency scenarios, the breeching inlet is constructed with durable materials. Its body is made of ductile iron, the inlet adaptor is crafted from copper alloy, the chains are stainless steel, and the cap is ABS plastic—all chosen for their strength and resistance to wear. Additionally, the inlet undergoes regular testing to confirm its functionality, guaranteeing it works reliably when emergencies occur. Without this component, firefighters would face significant challenges in accessing the necessary water supply, delaying fire - fighting efforts. Thus, it acts as a stable and consistent connection point, enabling firefighters to start extinguishing fires promptly and efficiently.
