AN Bulkhead Union RUBA

AN Bulkhead Union RUBA

↪ The Male AN Adapter, often referred to as RMAA, is a fitting commonly used in fluid transfer systems to connect AN fittings to components or ports with different threading standards.
↪ The AN Bulkhead Union, or RUBA, is a specialized fitting designed to pass an AN line through a panel, firewall, or any other barrier while maintaining a sealed connection on both sides.
↪ These adapters typically feature male AN threads on one end and a different type of thread on the other end, allowing for compatibility between AN fittings and other kinds of fittings or components.

➢Male AN Threads: One end of the adapter is equipped with male AN threads, which adhere to the Army-Navy sizing system. These threads ensure compatibility with other AN fittings that have corresponding female AN threads.
➢Applications: These adapters are commonly used in automotive, aerospace, marine, and industrial applications where AN fittings are prevalent. They allow for seamless integration of AN fittings into existing systems or components with different thread types.
➢Materials and Sizes: Male AN Adapters are available in various materials, including aluminium, steel, and stainless steel, to suit different applications and requirements. They also come in different sizes to accommodate the diverse needs of fluid transfer systems.
➢Alternate Thread Type: The other end of the adapter features a different type of thread, such as NPT (National Pipe Thread), BSPT (British Standard Pipe Thread), or metric threads. This allows the adapter to connect to components or ports with varying threading standards.
➢Versatility: Male AN Adapters provide versatility in fluid transfer systems, allowing AN fittings to be connected to a wide range of components or ports with different thread types. This versatility simplifies the assembly of liquid systems and facilitates compatibility between various parts.
Commonly used sizes for Male AN Adapters (RMAA) in fluid transfer systems, starting from the smaller sizes up to larger ones.
