● What are brass fitting and valves?
Brass fittings and valves are made from an alloy of copper and zinc. Brass is a strong, durable material that resists corrosion. This makes brass fittings and valves ideal for a variety of applications, including plumbing, heating and air conditioning systems.
Brass fittings and valves are a good choice for a variety of applications because they:
- Durable: Brass is a strong and durable material that can withstand high pressure and high temperatures.
- Corrosion Resistant: Brass resists corrosion, making it ideal for applications exposed to moisture or other corrosive elements.
- Versatility: Brass fittings and valves come in a variety of shapes, sizes and finishes, making them suitable for a wide range of applications.

● Connection standards for Brass fitting and valves
- ASME B1.20.1 is a standard published by the American Society of Mechanical Engineers (ASME) that specifies dimensions, tolerances, and methods of measurement for pipe threads. This standard mainly applies to threaded piping systems, including fittings, valves and pipes.
- ISO 7/1 is a standard published by the International Organization for Standardization (ISO) that specifies dimensions, tolerances and methods of measurement for threaded connections. This standard mainly applies to threaded piping systems, including fittings, valves and pipes.
- Both ASME B1.20.1 and ISO 7/1 specify dimensions, tolerances, and methods of measurement for threaded connections, but there are some differences between the two. For example, ASME B1.20.1 specifies thread diameter, pitch, and thread form, while ISO 7/1 specifies thread diameter, pitch, thread form, and thread length.
- The joining standards for copper fittings and valves comply with ASME B1.20.1 and ISO 7/1, meaning these fittings and valves can be joined according to both standards. This ensures that the fittings and valves are properly connected to avoid leaks and other problems.
