Stainless Reducing Unions - Imperial

Valco stainless reducing union
  • Easy connection of solvent lines
  • Low dead volume
  • For joining 1/16" OD tubing to 1/8" OD tubing

These reducing unions join 1/16" OD to 1/8" OD tubing. They are precision machined with a focus on the concentricity of the bore (0.75 mm) as well as on the finish of the surfaces to gave an absolute leak-free connection.

The unions have internal threads, which we recommend for most applications. Internal threads make stronger connections and internal fitting details provide the lowest dead volume for high performance instrumentation.
