Split-Seam, Butted-Seam Tubular Spacers and Tube Fabrications

Split-Seam, Butted-Seam Tubular Spacers and Tube Fabrications

Since 1989, Cook-Leitch Inc. has specialized in Split-Seam, Butted-Seam Tubular Spacers and Bushings. This high-speed stamping technology transitions coil stock material into a precision Split-Seam Tube. This offers a significant cost-savings opportunity vs. that of cut-off tubing and/or a machined spacer/bushing. In addition, we can produce your production Split-Seam Tube without tooling cost—thus, ease of entry for approval and capitalizing immediately on the cost-savings.
