Foster FST Series Couplers (Straight-Thru)
Foster FST Series full-flow straight-through hydraulic couplers and plugs — no valve in either half, so the inside diameter matches the nominal pipe for maximum flow. Standard Industrial Interchange with manual sleeve connection, body sizes 1/8" to 1-1/2". Brass, steel, and 303 stainless; ball-lock option available. Note: lines do not self-seal on disconnect.
