Connecting Sleeve / Coupler Ergom E12KA-01070100700 — Aluminum, 120 mm

Aluminum connecting sleeve Ergom E12KA-01070100700, 120 mm, is a lightweight, corrosion-resistant coupler designed to join or extend compatible pipes, rods or profiles. Manufactured from aluminum, this 120 mm sleeve provides a simple mechanical connection for assembly, repair or structural joining tasks where material weight and resistance to corrosion are important factors. The part is intended for use in applications such as construction framing, HVAC duct supports, furniture assembly and light industrial frameworks that accept an insert-style aluminum connector of this length.

Advantages

The aluminium construction gives a favorable strength-to-weight ratio and natural resistance to rust, reducing the need for additional coatings in many environments. At 120 mm length the sleeve offers sufficient overlap for secure connections while remaining compact for confined spaces. The product is compatible with systems that accept an insert-type coupler and facilitates fast mechanical joining without specialized adhesives. Its simple geometry supports repeatable alignment and straightforward installation.

Suitable for

• Joining or extending aluminum, steel or composite rods and profiles where inner diameter and tolerances match
• Light structural connections in construction framing and partition systems
• HVAC or ductwork support where a corrosion-resistant connector is required
• Furniture assembly and modular fixtures that use insert-style sleeves
• Repair and retrofitting tasks that require a compact, lightweight coupler

When it may not be suitable

This aluminum sleeve is not intended for high-load structural applications where engineered steel connectors or welded joints are required; its strength is limited compared with heavy-duty steel couplers. It may also be unsuitable when electrical conductivity or galvanic compatibility must be avoided without additional insulating measures.

Key specifications

• Material: Aluminum
• Length: 120 mm
• Function: Insert-style connecting sleeve / coupler for joining or extending profiles
• Typical uses: assembly, repair, structural joining in light industrial, furniture, HVAC and construction
• Surface: natural aluminum finish (uncoated)

How to use

Measure and confirm the inner diameter and tolerances of the pipes, rods or profiles to ensure compatibility with the insert sleeve. Slide the sleeve into or over the mating parts to achieve the required overlap, then secure the connection using the appropriate fastening method for the application — for example set screws, rivets, clamps or adhesive systems where recommended. Ensure alignment and check for play before finalizing the fix. For best results, prepare mating surfaces by cleaning away debris and corrosion to guarantee full contact.

What to consider before purchase

• Verify inner and outer diameters and tolerance compatibility with the parts to be joined
• Confirm that aluminum mechanical properties meet load and safety requirements for your application
• Consider whether surface treatment or insulation is needed to prevent galvanic corrosion with dissimilar metals
• Decide on the appropriate securing method (set screws, rivets, adhesive, clamps) for the intended use

Usage recommendations

Use this Ergom 120 mm aluminium sleeve for light to moderate joining tasks where corrosion resistance and low weight are priorities. For load-bearing or safety-critical connections, consult an engineer and select couplers rated for the expected loads or use mechanical fastening methods appropriate to the installation.
