HuaYou Pressed Sleeve Coupler for EN74 Scaffolding
HuaYou Pressed Sleeve Coupler is designed to join two OD48.3mm scaffolding tubes end to end, providing a secure external connection for tube-and-coupler scaffolding systems. Manufactured from high-strength steel plate, this pressed steel scaffold coupler delivers consistent dimensions and reliable connection performance for standards, ledgers, and braces.
Manufactured to EN74 Class B and BS1139 requirements, the coupler offers up to 9 kN slip resistance and is available with zinc-plated or hot-dip galvanized finishes for enhanced corrosion protection. Unlike an outer joint pin coupler, the sleeve coupler connects tubes externally, making it a practical solution for extending scaffold tube lengths.

Pressed Sleeve Coupler vs. Inner Joint Pin Coupler
Both products can be used to connect scaffold tubes end to end, but their connection methods are different.
| Feature | Pressed Sleeve Coupler | inner Joint Pin Coupler |
| Connection Position | Outside tube | Inside tube |
| Connection Type | External sleeve | Internal joint |
| Common Name | Sleeve Coupler / Joint Box | Inner Joint Pin |
| Tube Size | OD48.3mm commonly | OD48.3mm commonly |
| Installation | Slides over tube ends | Inserted into tube ends |
| Main Advantage | External, visible connection | Compact internal connection |
This distinction is useful when selecting between a Pressed sleeve coupler and an inner joint pin coupler for a tube-and-coupler scaffolding project.

HuaYou Scaffolding Coupler Range
HuaYou provides different scaffold couplers and clamps for tube-and-coupler scaffolding systems. Depending on the connection requirement, contractors can select different fitting types.
Pressed Steel Scaffold Coupler
Pressed steel couplers are formed from steel plate and are available for different scaffold connection applications, including sleeve and swivel configurations.
Swivel Coupler
A swivel coupler is designed to connect two scaffold tubes at adjustable angles and is commonly used for diagonal bracing and irregular scaffold structures.
Girder Coupler (Beam Clamp)
A girder coupler (beam clamp) is used to connect scaffold tubes to steel beams or structural members where a direct tube-to-beam connection is required.
Fence Clamp
A fence clamp is designed for connecting scaffold tubes used in temporary fencing, barriers and protection structures.
Outer Joint Pin Coupler
An outer joint pin coupler can be used as a tube-joining solution where the connection design requires an external or internal jointing arrangement depending on the specific product configuration.
FAQS
1. What is a pressed sleeve coupler?
A pressed sleeve coupler is a type of pressed steel scaffold coupler used to join two scaffold tubes end to end. The sleeve fits around the outside of the tubes to create an external tube connection.
2. What scaffold tube does the HuaYou sleeve coupler fit?
The standard model is designed for OD48.3mm scaffold tubes, which are widely used in British and European tube-and-coupler scaffolding systems.
3. What standards does the sleeve coupler meet?
The standard HuaYou sleeve coupler is designed according to EN74 Class B and BS1139 requirements. The reference model specifies 9 kN slip resistance.
4. Is the sleeve coupler galvanized?
Yes. HuaYou can supply sleeve couplers with zinc-plated or hot-dip galvanized finishes depending on the application and corrosion protection requirements.
5. What is the difference between a sleeve coupler and a swivel coupler?
A sleeve coupler connects two tubes end to end, while a swivel coupler connects two scaffold tubes at an adjustable angle, making it more suitable for diagonal bracing and angled structures.
