The DSP Blank Plug with Chain is a protective fire hose accessory used to seal unused DSP-type couplings, preventing the ingress of dust, dirt, and moisture. It ensures system cleanliness and readiness while providing a quick and secure closure for DSP fire hose outlets and hydrants.
Constructed from durable aluminum alloy or brass, the plug is engineered for corrosion resistance and long-term reliability. The attached retaining chain keeps the plug securely tethered to equipment, reducing the risk of loss during operation or maintenance.
