Ø28 mm Tube Connector for Structural Aluminium Profiles – for Series 30, 40 and 45 Profiles

The Ø28 mm tube connector for structural aluminium profiles is a practical fitting designed to connect a round aluminium tube with an external diameter of 28 mm to a structure made from aluminium T-slot profiles. It allows the modular Leanpipe tube system to be integrated with Series 30, 40 or 45 profiles, creating structures that combine lightweight tubular components with a stable profile frame.

The connector is particularly suitable for constructing roller guides, roller tracks, roller conveyors, flow racks, transport trolleys, assembly workstations and material-transport systems. It allows the end of an Ø28 mm tube to be mounted directly in the slot of a structural aluminium profile, creating a transition between two different modular systems.

The connector can be used with both a silver Ø28 mm round aluminium profile and a black Ø28 mm round aluminium profile. This makes it possible to match the appearance of the structure to the remaining components of the workstation, rack, trolley or production line.

The components required to attach the Ø28 mm tube to the connector are included with the product. The screws and T-slot nuts required to mount the connector to a structural aluminium profile are not included and must be purchased separately. Select the appropriate set for the chosen profile series.

Connecting an Ø28 mm Tube to an Aluminium T-Slot Profile

The 28 mm tube-to-T-slot profile connector allows the end of a round aluminium profile to be attached to the side of a slotted structural profile. The tube is inserted into the connector socket and secured using the mounting components supplied with the product.

The connector base is then mounted in the profile slot using two M6 screws and two compatible T-slot nuts. This mounting method allows the component to be positioned at the required height or location in the structure without drilling additional holes in the profile.

Before the screws are fully tightened, the connector position can be adjusted by moving it along the slot. This makes it easier to align the tube with a roller track, another structural component, the height of a rack or the layout of the complete workstation.

The connector can be used for:

• mounting the end of an Ø28 mm tube to a T-slot profile,
• connecting a Leanpipe structure to a frame made from aluminium profiles,
• mounting a roller guide or roller track,
• supporting a lightweight material-transport system,
• connecting a tube frame to an assembly workstation,
• creating a transition between a round tube and a slotted profile.

Tube Mounting Components Are Included

The connector is supplied with the components required to secure the Ø28 mm aluminium tube in the connector socket. There is therefore no need to purchase the basic parts required to secure the tube inside the connector separately.

During installation, place the tube in the dedicated socket, position it according to the planned structure and secure it using the included components. Tighten the mounting gradually while checking the position and stability of the tube.

Before installation, check that:

• the tube has an external diameter of Ø28 mm,
• the end of the profile has been cut square,
• the tube edges are free from burrs,
• the tube surface is clean at the mounting point,
• the tube is correctly aligned with the structure.

Profile Mounting Components Must Be Purchased Separately

The screws and T-slot nuts used to mount the connector to the structural aluminium profile are not included with the product. Select them according to the profile series and slot width.

The connector has two mounting points for attachment to the profile. Correct installation requires:

• 2 ISO 7380 screws with an M6 thread, with a length suitable for the selected profile series,
• 2 M6 T-slot nuts with geometry suitable for the selected profile series.

T-slot nuts for Series 30, 40 and 45 profiles have different geometries and should not be used interchangeably without first checking compatibility.

Mounting to Series 30 Aluminium Profiles

For structural aluminium profiles from Series 30 with an 8 mm T-slot, mount the connector using two silver M6×10 screws and two T-slot nuts designed for this series.

Components that must be purchased separately:

• 2× ISO 7380-M6x10
• 2× 8-4-M6.30

The 8-4-M6.30 T-slot nuts are matched to the slot geometry of Series 30 profiles. ISO 7380 M6×10 screws provide stable attachment of the connector base without requiring additional profile machining.

Mounting to Series 40 Aluminium Profiles

To install the connector on structural aluminium profiles from Series 40 with an 8 mm T-slot, use two black M6×12 screws and two T-slot nuts intended for this profile series.

Components that must be purchased separately:

• 2× ISO 7380-M6x12 BLACK
• 2× 8-4-M6.40

The 8-4-M6.40 T-slot nuts are designed for the slots of Series 40 aluminium profiles. The black ISO 7380 M6×12 screws provide a neat finish to the visible mounting points and complement black structural components.

Mounting to Series 45 Aluminium Profiles

For aluminium profiles from Series 45 with a 10 mm T-slot, use two black M6×16 screws and two T-slot nuts suitable for a 10 mm slot.

Components that must be purchased separately:

• 2× ISO 7380-M6x16 BLACK
• 2× 10-4-M6.45

The 10-4-M6.45 T-slot nuts are intended for Series 45 profiles with a 10 mm T-slot. The longer ISO 7380 M6×16 screws allow the connector to be pressed correctly against the profile surface.

Installing the Tube Connector on an Aluminium Profile

Installation involves placing the Ø28 mm tube in the connector, securing it with the included components and mounting the connector base in the slot of the structural aluminium profile.

1. Prepare the tube: check its external diameter, cut quality and the condition of the edges.

2. Insert the tube into the connector: slide the end of the Ø28 mm round profile into the dedicated socket.

3. Secure the tube: use the mounting components supplied with the connector and pre-tighten them.

4. Place the T-slot nuts in the profile: insert two M6 T-slot nuts suitable for the selected profile series into the T-slot.

5. Position the connector: align the two holes in the connector base with the threads in the T-slot nuts.

6. Install the correct screws: use M6×10 for Series 30, M6×12 BLACK for Series 40 or M6×16 BLACK for Series 45.

7. Adjust the position: before fully tightening, check the height, direction and position of the tube in relation to the complete structure.

8. Tighten the connection: tighten both screws securing the connector to the profile gradually and evenly, then check the tube mounting inside the connector.

9. Check stability: before use, ensure that the tube and connector do not move in relation to the profile.

Tighten the screws carefully and in accordance with the requirements of the complete structure. The modular mounting method allows the connection to be loosened later, the connector position to be changed or the components to be used in another configuration.
