Pipe couplings RK31 black

Unsure about the dimension? Measure the wall thickness of the tube and get in touch, we will double check against the data sheet.

The T shape is used in the middle of a tube length, where a crossing tube connects to a continuous beam or a leg. Shelves, intermediate braces and dividers in racks are typical cases; the beam runs unbroken through the connector and keeps its stiffness.

RK31 is a T-shaped three way connector for square tube, made in nylon PA6. The series covers square tube 20x20 and 25x25 mm with a wall thickness of 1.5 mm, and you pick the dimension as a variant here on the product page. The connector is pressed into the tube ends and builds the structure together without welding; cut the tubes, fit the connector and tap the parts together with a rubber mallet. This product, Tube Connectors RK31 black, has the format 25x25 mm, which makes it easy to place into an existing structure.
