Wyes and Siamese

Precision Fireground Water Flow Control

Darley’s Wyes & Siamese line keeps your crew’s water supply adaptable under pressure. Whether you need a lightweight leader-line gated wye or a rugged clappered Siamese, these adapters let you split a single supply or merge multiple lines with confidence. Options include quarter-turn models with long, easy-grip handles for fingertip flow control, ideal when precise, second-by-second adjustments are required. Choose from 2-way and 3-way Siamese or gated wyes in Storz, NH, or NST sizes to match your LDH or attack-line setup. Built by trusted manufacturers, Akron Brass, Harrington, Kochek Company, and C & S Supply, each valve combines corrosion-resistant alloys, smooth-acting gates or clappers, and NFPA-ready durability, allowing you to move, split, or supplement water flow without hesitation.
