Swagelok SS-1210-6-4 Stainless Steel Reducing Union Fitting

Swagelok SS-1210-6-4 is a stainless steel reducing union tube fitting that connects a 3/4-inch outer-diameter tube on one end to a 1/4-inch outer-diameter tube on the other. The SS prefix denotes stainless construction, and retailers commonly list this model as 316 stainless steel, with Swagelok tube-end connections designed to provide a secure, leak-tight seal in tubing circuits. As a reducing union, SS-1210-6-4 combines two different tube OD sizes in a single body and is identified by its basic ordering number SS-1210-6-4. Use this fitting anywhere a compact, durable, corrosion-resistant transition between 3/4 in. and 1/4 in. tubing is needed within a Swagelok system.
