Threaded Elbow

What is a Threaded Elbow?

A Threaded Elbow is a pipe fitting designed to change the direction of flow in a piping system, usually at angles of 90° or 45°. It connects two threaded pipe ends and eliminates the need for welding, making it ideal for quick and easy installations in low to medium-pressure piping systems. These elbows are commonly used in plumbing, oil & gas, chemical processing, marine, and fire protection applications.

Threaded elbows are available in NPT, BSP, BSPT, and ISO metric threads, and are manufactured from materials such as carbon steel, stainless steel, and alloy steel to suit diverse industrial environments.

Key Features

  • Secure Directional Flow – Provides leak-resistant flow changes in piping systems.

  • Tool-Free Installation – No welding needed; easy to screw in or replace.

  • Angle Variants – Available in 45° and 90° configurations to suit layout needs.

  • Threaded for Tight Sealing – Ensures mechanical seal with NPT, BSPT, or BSP threads.

  • Standards-Compliant – Manufactured as per ASME, ASTM, and DIN specifications.

Types of Threaded Elbows

  • 90° Threaded Elbow
  • 45° Threaded Elbow
  • Reducing Threaded Elbow
  • Street Elbow (Male-Female Threaded)

Do you have questions?

It redirects flow at a 45° or 90° angle without welding, allowing for flexibility in piping layouts.
Yes. Reducing threaded elbows are used to connect different pipe sizes while changing direction.
We supply elbows in NPT, BSP, BSPT, and ISO Metric thread types.
Yes. If the threads remain intact and sealing is properly done, they can be reused.
