Reducer Coupler Fittings Manufacturers | Leo Industries
Reducer Coupler Fittings
Reducer coupler fittings are essential mechanical splicing components used in reinforced concrete structures to join two rebars of different diameters. At Leo Industries, we manufacture precision-engineered reducer couplers that ensure a seamless transition of load between varying bar sizes. These fittings are critical for high-rise buildings, bridges, and infrastructure projects where the reinforcement design requires a change in rebar thickness across different levels or sections.
Working Principle & Process Flow
The working principle of reducer coupler fittings involves internal threading that corresponds to two different rebar sizes. One end of the coupler is bored and threaded to match a larger diameter bar, while the opposite end is designed for a smaller bar. The process flow begins with threading the rebar ends using a specialized threading machine. Once threaded, the reducer coupler is screwed onto the bars, creating a continuous reinforcement path that maintains the structural capacity of the joint without the need for overlapping or welding.

Ensure both rebars are screwed into the coupler until they meet the center
Conduct a visual inspection for any exposed threads after tightening
FAQs — Reducer Coupler Fittings
Q1
What are reducer coupler fittings used for?
They are used to join two rebars of different diameters, allowing for a smooth transition in reinforcement size while maintaining the structural strength of the joint.
Q2
Can I use these couplers for all types of rebars?
Yes, they are compatible with most high-strength TMT bars, provided the bar ends are properly threaded to match the coupler specifications.
Q3
Are they better than lap splicing?
Yes, reducer couplers offer a more reliable mechanical connection, reduce steel congestion, and eliminate the potential weaknesses associated with long lap lengths.
Q4
Do they require special inspection?
Standard quality checks, such as visual thread inspection and torque verification, are usually sufficient to ensure a safe and effective splice.
Q5
What size combinations are available?
We manufacture a wide range of combinations, including 16mm-20mm, 20mm-25mm, 25mm-32mm, and many others to suit your specific project requirements.
