SafeWay's S70 Series offers unique internal valving, combined with SafeWay's two-way sleeve feature, allowing one-hand connection under full system pressure. The body (coupling) half can be mated to either a ball valve or poppet valve ISO male tip (nipple). The S70 Series is used primarily with agricultural equipment. It is original equipment on full size tractors and front-end loaders. Use when connection and disconnection under pressure, without the use of tools, is desirable.
