Can Sleeve Couplers be used for horizontal connections?

Sleeve couplers are optimized for vertical, end-to-end connections. For horizontal or angled joints, right-angle or swivel couplers are more appropriate.

What is the difference between a Sleeve Coupler and a Prop Sleeve?

A sleeve coupler connects two tubes externally in scaffolding. A prop sleeve is a welded component within an MS prop for adjusting height.

Are these couplers compatible with galvanized tubes?

Yes. Our sleeve couplers are compatible with both black and galvanized 48.3 mm OD tubes.

Are Avanza sleeve couplers certified?

Yes, our products meet Indian and international quality standards for scaffolding safety.

Sleeve Couplers: Reliable and Strong Connectors for Scaffolding Systems

Sleeve couplers are essential components in steel scaffolding systems, specifically used to connect two scaffold tubes end-to-end in a straight line. At Avanza Steel, our sleeve couplers are engineered to meet stringent quality standards, ensuring reliable jointing for vertical connections and extended tube lengths. These couplers are designed to securely grip 48.3 mm OD scaffolding pipes, maintaining structural integrity during heavy-duty construction or industrial work.

Unlike prop sleeves, which are fabricated as part of an MS Prop assembly and serve height adjustment purposes, sleeve couplers are independent accessories primarily used for tube connection. Understanding this distinction is key when specifying the right component for your scaffolding system.

Use Case: How Sleeve Couplers Work in Scaffolding

Sleeve couplers are ideal for vertical tube connections where extended height is required. They:

Serve as connectors between two upright tubes aligned vertically
Reinforce structural rigidity without displacing alignment
Are frequently used in tower scaffolding or tall formwork systems

To install, the coupler is inserted halfway into each pipe end and tightened using scaffold bolts to ensure a non-slip connection.

Handling & Storage

Stored in covered warehouses to avoid exposure to moisture
Packed in uniform bundles for easy transportation
Regular inspection for coating quality and bolt grip strength
