Description
Rolled Edge to Slip Adapter – Galvanised Steel | 80mm to 500mm
The rolled edge to slip adapter is a precision-engineered galvanised steel transition fitting that connects spiral pipe or flexible ducting to a rolled edge duct system. It bridges the two most common industrial ventilation standards, allowing contractors and engineers to integrate different duct types within the same system without fabricating custom joints on site.
Available in 14 diameters from 80mm to 500mm to suit standard HVAC, ventilation, and extraction installations. Manufactured from high-quality galvanised steel for long-term corrosion resistance in commercial and industrial environments.
Technical Specifications
| Property | Value |
|---|---|
| Material | Galvanised steel |
| Connection Type A | Rolled edge (female socket) |
| Connection Type B | Slip end (male spigot for spiral pipe or flex) |
| Available Diameters | 80, 100, 125, 150, 180, 200, 224, 250, 300, 315, 350, 400, 450, 500mm |
| Finish | Galvanised (zinc-coated for corrosion resistance) |
| Standard | Compatible with DW/144 and standard rolled edge systems |
| Installation | Push-fit slip end; rolled edge secured with matching collar |
Key Features
- Bridges Two Duct Systems — Eliminates the need for site-fabricated transitions between spiral pipe/flex and rolled edge systems
- High-Quality Galvanised Steel — Resists corrosion in damp, high-humidity, and outdoor-adjacent ventilation environments
- Easy Fit Design — Slip end pushes directly onto spiral pipe or flex duct; rolled edge end connects into standard rolled edge fittings
- Fast Installation — No special tools required; significantly reduces installation time on site
- Full Diameter Range — 80mm to 500mm covers the majority of commercial and industrial HVAC applications
- Air-Tight Fit — Precision-formed ends minimise air leakage at the transition point
Installation Notes
The slip end connects to spiral pipe or flexible duct — secure with a self-tapping screw and seal with duct tape or mastic sealant for airtight joints. The rolled edge end connects into standard rolled edge duct sections or fittings. Ensure the adapter diameter matches both the spiral pipe and rolled edge system diameter.
Applications
- Commercial HVAC and air handling systems
- Industrial extraction and ventilation installations
- Retrofitting spiral duct systems into rolled edge networks
- Kitchen extraction and canopy ducting
- Clean room and controlled environment ventilation
- Agricultural and process ventilation
