Connection piece with joint SPC D200–D180 (male/male) for duct transition

SPC connection piece with joint D200–D180 (male/male) is a metal duct fitting engineered to connect circular ventilation ducts with diameters of 200 mm and 180 mm while providing an articulated joint. The fitting enables a stepped reduction between two duct sizes and a secure mechanical connection to maintain airflow continuity. It is intended for use in ventilation and air distribution systems where a compact transition and flexible alignment are required.

Advantages

The connection piece combines a reliable stepped reduction with an integrated joint that assists in alignment during installation. Constructed to provide a tight mechanical fit, it reduces the risk of air leakage at the transition point and preserves duct geometry for consistent airflow. The male/male ends simplify coupling with standard female fittings and clamps, and the compact design supports installations in confined spaces.

Suitable for

• Transitioning between circular ducts of 200 mm and 180 mm diameter
• Ventilation systems in residential and commercial buildings
• Situations requiring an articulated or adjustable connection for alignment
• Retrofit or new ductwork installations where space is limited

Key specifications

• Connection type: male/male articulated joint for circular ducts
• Input diameter: 200 mm
• Output diameter: 180 mm
• Function: stepped reduction with mechanical joint for alignment
• Material: metal suitable for standard ventilation ductwork
• Application: air distribution and ventilation systems

How to use

Position the SPC D200–D180 male/male connection piece between the corresponding female duct ends, ensuring the 200 mm end aligns with the larger duct and the 180 mm end with the smaller duct. Use appropriate clamps or fasteners to secure both male ends into the mating female fittings, and tighten evenly to maintain alignment. Adjust the articulated joint as needed to correct angular misalignment before final tightening. After installation, inspect joints and seals visually and, if applicable, apply duct sealant or tape to improve airtightness following local standards.

Usage recommendations

When installing the connection piece, verify compatibility with existing duct material and fastening methods. Select corrosion-resistant fasteners in humid environments and follow ventilation system design guidelines to minimize pressure loss across the reduction. Routine inspection of the joint and any applied sealant is recommended during system maintenance.
