Description
A reducing coupling joins two pipes of different sizes in a straight line. It has a larger socket or thread at one end and a smaller one at the other. Therefore, the line can step down without a separate reducer. We stock reducing couplings at our showroom in Nad Al Hamar, Dubai, for same-day collection across the UAE.
First, note both pipe sizes, for example 1″ x 3/4″. Next, choose the end type: threaded for quick fitting, or socket weld for high pressure. Finally, choose carbon steel A105 for oil and steam, or stainless steel 316L for chemicals and seawater. In addition, we can supply matching nipples and bushings for the same line.
Why Choose Our Reducing Coupling
- Compact joint: One fitting does the job of a coupling and a bushing.
- High pressure: Forged couplings come in Class 3000 and Class 6000.
- Two end styles: Threaded NPT or BSPT, or socket weld for welded lines.
- Traceable steel: In addition, EN 10204 Type 3.1 certificates are available on request.
