Male Threads: Types and Uses in Plumbing
What Is a Male Thread? A male thread is an externally threaded component designed to screw into a corresponding female thread (internal thread). Male threads are commonly used in industrial plumbing, gas, oil, and water systems to create NPT, BSP, and metric threads for high-pressure and corrosion-resistant male threaded applications. Key Features: Connect other female thread […]
Material and Thread Standards for Pipe Fittings Explained
When sourcing pipe fittings in international trade, buyers often focus on two critical aspects: material standards and thread standards. Different regions have their own commonly used standards for stainless steel fittings and carbon steel fittings, which ensure compatibility, safety, and durability in industrial piping systems. This guide explains the popular pipe fitting standards in different […]

Pipe Coupling Size Guide: How to Choose the Right Size
Introduction In industrial piping systems, selecting the correct pipe fitting size is critical for ensuring safety, reliability, and long-term performance. Among the most commonly used fittings in threaded piping networks is the pipe coupling. This small but essential pipe fitting connects two pipes or pipe nipples together, allowing pipelines to extend, repair, or adapt to […]
How to Choose Pipe Coupling Size: Engineer’s Guide
Introduction Choosing the correct pipe coupling size is not as straightforward as it looks. Most errors come from confusing the nominal pipe size and the actual size.Most errors come from confusing thenominal pipe sizeand the actual size. Thus, a “3/4-inch pipe” does not have an outside diameter of 3/4 inch. Pipes and fittings supply, sizing disputes, and specification errors are […]
