Available in various reducing sizes (e.g., 1" x 3/4")
Product Introduction
A stainless steel bushing, also known as a male/female bushing, is a cleverly designed pipe fitting. It features both male and female threads and is designed to reduce the diameter of a pipe within an existing female-threaded port. For example, it can convert a DN50 port to a DN25 port.
Compared to using a "reducing coupling + union" combination, a single bushing can achieve a diameter reduction, providing an ideal solution for saving installation space, reducing costs, and minimizing leaks in pipeline connections.
Material Properties
The 316/CF8M stainless steel material provides the bushing with enhanced corrosion resistance. The addition of molybdenum enhances its resistance to chlorides and various chemical media compared to 304 stainless steel.
It is suitable for applications requiring more stringent conditions than standard, such as mild chemical processes, humid coastal air, or water treatment systems, ensuring the long-term integrity and reliability of threaded connections.
Application Scenarios
Connecting small-diameter instrument or sampling branches from main pipe headers
Matching outlet port size of valves and pumps to smaller downstream pipes
Adjusting and adapting to different threaded port sizes during equipment assembly and maintenance
Note on Materials & Standards
According to ASTM A351, the official designation for cast 316 stainless steel is CF8M. While the chemical compositions of the two differ slightly, the industry generally accepts that materials designated "316" meet the performance requirements of CF8M. Similarly, while SMLSCO product dimensions reference standards such as MSS-SP-114, they are primarily manufactured to widely accepted industry specifications to ensure market compatibility and practicality.
Frequently Asked Questions
Q1: What is the difference between this NPT-threaded 316 reducer bushing and a reducer coupling?
A1: A reducer coupling has female threads on both ends, whereas this reducer bushing features a compact hex head design with male threads on the outside and female threads on the inside. It can be screwed directly into a female threaded port to achieve a size transition, saving more space than a coupling in pipeline installations with limited space and effectively reducing potential leak points.
Q2: The product description mentions compliance with the MSS-SP-114 standard. How does SMLSCO ensure the dimensions and quality of this reducer sleeve?
A2: MSS-SP-114 is a specialized dimensional and quality standard for stainless steel cast threaded pipe fittings. All our relevant manufacturing facilities are ISO and PED certified, and we conduct 100% rigorous quality inspections prior to shipment to ensure that product dimensional accuracy and pressure-bearing capacity fully meet the standards.
Q3: What are the advantages of 316/CF8M reducer sleeves when used in marine or chemical processing systems?
A3: They offer superior resistance to chloride ion and chemical medium corrosion, providing a longer service life and significantly reducing maintenance costs.
Q4: If we urgently need this batch of 316 reducer sleeves for equipment assembly or on-site maintenance, can you guarantee fast delivery?
A4: SMLSCO specializes in rapid delivery for industrial piping systems. We maintain a 10,000-square-meter indoor warehouse with ample stock of standard specifications year-round, enabling us to shorten lead times to within 2 weeks. Our professional team responds to your purchase orders within 15 hours.
