The BS336 Blank Cap / Plug with Chain is designed to protect British Standard Instantaneous (BS336) fire hose couplings when not in use. This durable cap securely seals the coupling to prevent dust, debris, water ingress, and mechanical damage, helping to maintain equipment readiness in fire protection systems.
Equipped with a retaining chain, it ensures the cap stays attached to the outlet or fitting, reducing the risk of loss during operation or maintenance. Constructed from corrosion-resistant aluminum or brass, it is ideal for both indoor and outdoor use in harsh environments.
