These manifolds, which go from one or two pipe fittings to three Valco zero dead volume fittings, minimize the number of connections between a regulator and the various carrier gas lines in a chromatographic system. The models with two pipe fittings go a step further, allowing the support of a gauge, a second regulator, or a valve leading to a separate system.

Standard material is 300 series stainless. Versions in Hastelloy C and titanium, or with additional Valco zero dead volume fittings, are available on a special order basis.
