Product Description

BSP & NPT Brass Threaded Couplings

Threaded couplings are commonly used in industrial applications. They serve as cost-efficient solutions for effective connection between components. Threaded couplings consist of two areas with threading that allow two different parts to be joined together.

Norwood Screw Machine manufacturers precision couplings to ensure that the union is seamless. We pride ourselves on manufacturing products that are reliable and durable. Several variations in size, threading, material, length, etc. are available when manufacturing custom brass threaded couplings.

Types of Threaded Couplings

Brass threaded couplings are divided into three main categories viz.:

  1. Half Threaded Couplings
  2. Full Threaded Couplings
  3. Threaded Reducing Couplings

Thread Types

Couplings are threaded according to two standards. The specifications of both standards are unique and specifically tolerance. This eliminates any possibility of incorrect assembly. Brass threaded couplings are manufactured in the following thread types:

  1. BSP
  2. NPT
