In firefighting equipment, a delivery hose coupling is a specialized connector designed for seamless water transfer within firefighting systems. These couplings serve to join sections of delivery hose or connect hoses to other essential firefighting equipment such as pumps, hydrants, or nozzles. They play a pivotal role in ensuring the efficient flow of water or firefighting agents from the water source to the point of use. Delivery hose couplings typically feature two main components: Male Coupling: This component boasts external threads, facilitating its insertion into the female coupling or other firefighting apparatus. Female Coupling: The female coupling is equipped with internal threads that align with the external threads of the male coupling. When connected, the male coupling is screwed into the female coupling, creating a secure and watertight seal. Crafted from durable stainless steel, these couplings ensure longevity and reliability in demanding firefighting environments. With a size of 63 MM and adherence to the IS 903 standard, they meet industry specifications for compatibility and performance. Employing an instantaneous type connection, they enable swift and hassle-free assembly, crucial for rapid deployment during firefighting emergencies. Additionally, these couplings undergo rigorous testing, withstanding pressures of up to 21 kgf/cm2 to ensure robustness and effectiveness in firefighting operations. Duly ISI marked, they guarantee compliance with stringent quality and safety standards, instilling confidence in firefighters when combating fires and safeguarding lives and property.
