Shanghai Quanbao Electronic Materials Technology Co., Ltd., based in Shanghai, China, proudly introduces our premium Stainless Steel Single End Welded Joint Male Threaded Ferrule Fitting. Engineered for pipe systems, this fitting delivers unmatched corrosion resistance and durability in demanding industrial environments. As a trusted manufacturer, we utilize advanced welding techniques to ensure leak-proof connections, enhancing system reliability. Our commitment to quality and innovation makes this product a top choice for global clients seeking robust piping solutions.
This fitting excels in various applications due to its unique design and superior material properties. Key features include:
High corrosion resistance: Made from grade 304 or 316 stainless steel, it withstands harsh chemicals and extreme temperatures, extending the lifespan of your pipe systems.
Easy installation: The male threaded end allows for quick, tool-free connections, while the welded end ensures a permanent, secure bond, reducing maintenance downtime.
Versatile compatibility: Suitable for a wide range of pipe diameters and materials, including metal and plastic, making it ideal for industries like chemical processing, oil and gas, and water treatment.
Although this part has a threaded and hexagonal structure and may be colloquially referred to as a "plug," judging from its deep cylindrical cavity at the top and overall shape, it is actually a single-ended welding adapter (often called a plain shank union or cup union within the industry).
This type of adapter is typically used at the end of piping systems. Its internal cylindrical cavity is designed for manual welding (socket weld) directly to a tube, or to serve as a connection port for instrument impulse lines or precision equipment.
To help you fully understand and provide accurate selection criteria, I have listed the core parameters for this welding adapter and for the conventional ferrule cap you mentioned.
I. Core Parameters of This Part (Single-Ended Welding Adapter)
If you are looking for the part shown in the image, you typically need to pay attention to the following key dimensions:
Thread Specification: The external thread at the bottom determines which equipment or flange it can be screwed into. Common specifications include metric M14, M20 or imperial G1/2, R1/4, etc.
Plain Shank/Cup Inner Diameter: The diameter of the hollow interior at the top determines the outer diameter of the tube it can accommodate. Common examples include Φ6mm, Φ8mm, Φ10mm, etc.
Hexagon Across Flats Dimension: The width of the hexagon on the side (often called the S value) determines the size of wrench you need to tighten it.
Material and Temperature/Pressure Resistance: Common materials include 304/316 stainless steel, brass, etc. The maximum working pressure for this type of adapter is typically between 1.0 MPa and 40 MPa, depending on the specific structure and material.
II. Core Parameters of a Conventional "Ferrule Cap"
If you subsequently need to purchase a ferrule-type cap for sealing a pipeline, its parameter logic is completely different from that of the welding adapter:
Tube Outer Diameter Specification: The ferrule cap fits over the outside of the tube. Its core parameter is the tube outer diameter (OD) it accommodates, e.g., Φ6mm, Φ10mm, etc.
Thread Type: The tail thread used for tightening and securing. Common types include ZG, G (BSPP), NPT, etc.
Sealing Method:
Cone Seal: Relies on the cone surface at the front of the cap compressing against the ferrule to create a seal.
O-Ring Seal: Relies on a rubber O-ring for a face seal, allowing for easier assembly and disassembly.
Manufacturing Standards: Common national standards (e.g., GB/T 3760) or international standards (e.g., ISO 8434-1). These standards specify mechanical dimensions such as the total length (L) of the cap and the hexagon across flats (S) for different tube diameters.
💡 Suggestion:
If you plan to purchase this part shown in the image to replace an interface on your equipment, it is recommended that you use a caliper to measure the external thread diameter at the bottom (to determine the thread specification) and the inner diameter of the hollow cavity at the top (to determine the tube size). This will help you find an exact matching model.
Advantages for your operations include reduced leakage risks, lower replacement costs, and enhanced safety. The ferrule design provides a tight seal, minimizing fluid loss and improving efficiency. Clients report up to 30% longer service life compared to standard fittings, translating to cost savings and fewer disruptions.
