Swagelok SS-1210-4 Tube Union Cross Fittings

SS-1210-4 is a stainless steel Swagelok tube fitting that serves as a four-port union cross for 3/4 in. tube OD. This union cross creates a single cross junction by joining four runs of 3/4 in. outer-diameter tubing in a compact, stainless-steel body. Each port uses Swagelok’s standard union nuts and ferrules, delivering consistent, reproducible tube-to-tube connections when assembled per Swagelok practices. The 3/4 in. tube OD specification identifies the compatible tubing size, making this part a common choice for instrumentation and process-piping applications where a space-efficient cross junction is required. The stainless steel construction provides corrosion resistance and durability in demanding environments, including high-pressure or high-purity systems where material compatibility matters. Whether routing four lines through a single point or creating a discrete cross-branch network, the SS-1210-4 offers a robust, reliable solution from a trusted brand in fluid-system fittings.
