Reducer Coupling Threaded
A reducer coupling threaded is a specialized mechanical splice used in the construction industry to join two reinforcement bars of different diameters. Leo Industries manufactures these high-precision threaded couplings to ensure a seamless load transfer between varied rebar sizes, eliminating the need for complex welding or space-consuming lap splices. By utilizing precision-cut internal threads, these couplings provide a rock-solid connection that maintains structural integrity across the transition zone.
Working Principle & Process Flow
The working principle of a reducer coupling threaded involves the use of high-grade steel sleeves with two different internal thread sizes. The process begins by preparing the ends of the rebars using a threading machine to match the specific pitch and depth of the coupler. The larger bar is typically screwed into the wider end of the coupling, followed by the smaller bar into the narrower end. This mechanical interlocking ensures that the bars are perfectly aligned, allowing the joint to handle the same tensile and compressive forces as a continuous piece of steel reinforcement.

ChecklistLeoindustries
Pre-Installation
Ensure rebar threads are cleaned of concrete slurry and dirt
Verify the thread pitch on the bar matches the internal coupler thread

Verify that both bars are fully engaged within the coupling body
Mark installed joints to indicate that torque has been applied
FAQs — Reducer Coupling Threaded
Q1
What is a reducer coupling threaded?
It is a mechanical connector used to join two rebars of different diameters by means of internal threads, ensuring a strong transition between bar sizes.
Q2
Can these be used for any TMT bar?
Yes, as long as the bar ends are properly threaded to match the coupler's internal threading, they can be used with all standard grade TMT bars.
Q3
What is the advantage over lap splicing?
Unlike lap splicing, which requires long bar overlaps and can lead to concrete congestion, threaded couplings provide a direct mechanical connection that is more space-efficient and reliable.
Q4
Do I need special equipment to install them?
You will need a rebar threading machine to prepare the bar ends and a torque wrench to ensure the coupling is tightened to the required structural specifications.
Q5
Are they suitable for seismic zones?
Yes, our high-strength threaded couplers are designed to meet performance requirements that make them suitable for use in earthquake-resistant structures.
