Brass Reducing Coupling

A brass reducing coupling is a type of pipe fitting used to connect two pipes of different diameters in a plumbing or hydraulic system. It ensures a secure, leak-proof connection while transitioning between pipe sizes.

Key Features of Brass Reducing Coupling:

✔ Material: Made from high-quality brass (often DZR - Dezincification Resistant) for corrosion resistance and durability.

✔ Thread Type: Typically features male (MPT) or female (NPT/BSP) threads for a tight seal.

✔ Pressure & Temperature Rating: Suitable for moderate to high-pressure applications (varies by size and design).

✔ Applications: Used in water supply, gas lines, HVAC, and industrial piping systems.

Common Sizes Available:

Brass reducing couplings come in various combinations, such as:

1/2" x 3/8"

3/4" x 1/2"

1" x 3/4"

1-1/4" x 1"

Other custom sizes available

Types of Brass Reducing Couplings:

Hex Head Reducing Coupling – Has a hexagonal middle for easy wrench tightening.

Straight Reducing Coupling – Smooth body, used where space is limited.

Female x Female (FxF) or Male x Female (MxF) – Different thread configurations.

Installation Tips:

Use Teflon tape or pipe thread sealant for a leak-proof seal.

Tighten with a wrench, but avoid over-tightening to prevent damage.
