What Are Swage Nipples & Reducing Nipples?

Swage Nipples, also known as Reducing Nipples, are short fittings used to connect pipes of different diameters. They are forged or machined to ensure high pressure strength and reliability.

• Concentric Swage Nipples: Aligned centerlines, used in vertical pipelines.

• Eccentric Swage Nipples: Offset design, prevents air pockets and cavitation in horizontal pipelines.

These fittings are available with threaded, socket weld, and butt-weld ends, making them versatile for various piping systems.
