This item is a 304 stainless steel female to female thread reducer pipe fitting connector adpater. It provides two female threaded ends and is offered in multiple size configurations, with DN15 and DN20 options. The design is intended to join male threaded pipes or fittings of different sizes in stainless steel piping systems. Key benefits Corrosion resistant stainless steel construction for durability in a variety of environments. Two female threaded ends allow easy connection between mating malethreaded components. Available in multiple size configurations to accommodate a range of piping needs from small to large diameter runs. Reliable, solid performance for everyday piping applications in water, air, and light chemical service when paired with appropriate seals and fittings. Key attributes Material: 304 stainless steel for strength and corrosion resistance. Ends: female to female threaded ends (reducer style) for connecting differing pipe sizes. Size options: 1/4', 1/2', 3/4', 1', 11/4', 11/2', 2' with corresponding DN values DN15 and DN20. Functionality: pipe fitting connector adpater designed to reduce from a larger to a smaller threaded connection in a single component. Compatibility: designed to mate with standard malethreaded fittings in the listed size range (verify thread standards and mating components for your application). Size options and DN values 1/4' (DN15) 1/2' (DN15 or DN20 variants) 3/4' (DN20) 1' (DN20) 11/4' (DN20) 11/2' (DN20) 2' (DN20) Applications and use cases Plumbing and refrigeration systems where a larger pipe must be connected to a smaller, femalethreaded segment without changing the overall layout. Industrial piping setups that require a durable, corrosionresistant reducer to connect two different sized threaded sections. Marine or outdoor installations where stainless steel fittings provide longterm resistance to the elements while maintaining reliable connections. Installation considerations Confirm the correct two mating malethreaded components match the ends of the reducer and are within the listed size range. Use appropriate thread sealing methods per local codes and the specific fluid being conveyed. Tighten to the recommended torque for the specific thread type being used, and inspect connections after installation for leaks. Notes The product is marketed as a female to female thread reducer pipe fitting connector adpater in 304 stainless steel, available in the size options listed above with DN15 and DN20 configurations. No additional components are included; ensure you select the exact size configuration to match your system requirements. This description reflects the original product specifications and feature set, emphasizing the material, dual femalethreaded reducer design, the range of sizes, and practical applications for reliable stainless steel piping connections.
