Most Demanded Brass Compression Fittings Manufacturers in India
Precious Metal Industries are a long established manufacturer and exporter of compression fittings from India precision machined for a wide variety of plumbing, hydraulic, pneumatic, instrumentation, automotive and industrial applications. Brass compression fittings are used to join pipes and tubes in a secure manner without the need for welding or sophisticated joining techniques. They are mechanically strong, corrosion resistant, easily machined and have accurate threading, making them ideal for applications where reliable and repeatable connections are needed.
Precious Metal Industries is a well established company in Jamnagar, Gujarat which specializes in the manufacture of brass components with emphasis on compression fittings. They have a reputation for making custom brass compression fittings from customer drawings, samples and technical specifications. The company provides a variety of materials, thread specifications, sizes and finishes that can be used depending on the application specifications.
What Are Brass Compression Fittings?
Brass compression fittings are mechanical fittings to join pipes or tubes tightly. A standard compression connection contains a fitting body, compression nut and ferrule or compression ring. The nut is tightened to form a mechanically tight connection with the tube by the ferrule.
These types of fittings can also be advantageous for a piping system where easy installation, maintenance or disassembly is desired. Permanently joined connections require welding equipment to make the connection, where as compression fittings do not require any welding equipment to make the connection, which is convenient for many plumbing, pneumatic, hydraulic and instrumentation applications.
The type of compression fitting is selected based on tube material, tube size, operating pressure, temperature, thread configuration and the fluid/gas to be used.
Precision Brass Compression Fittings Manufacturer
High tolerances in the manufacturing of precision compression fittings ensure that dimensional deviations do not have a negative impact on the engagement of the tubes, their compatibility with threads and on the performance of the assembly. Precious Metal Industries produces brass parts that are created from appropriate brass materials that can be Brass 319 or BS 249, depending on the customer’s needs, and the composition of the parts can be customized.
Automatic turning, CNC machining, drilling, tapping, threading, grooving, profiling and deburring are processes that can be employed in the manufacturing process. Dimensional inspection is done to ensure uniformity of production runs.
The fittings can be manufactured according to specific customer requirements for:
- Fitting dimensions
- Tube connection sizes
- Thread specifications
- Overall length
- Hex dimensions
- Internal and external profiles.
- Material composition
- Surface finish
- Packaging requirements
Determine Thread Size of Brass Compression Fittings
One of the key factors to keep in mind when choosing brass compression fittings is their compatibility with the threads. Based on the product design and customer specification, Precious Metal Industries can produce brass parts based on different thread specifications.
| Thread Standard | Application |
| ISO Metric | Industrial and international equipment |
| MM | Metric piping and mechanical assemblies |
| BSP | Plumbing and fluid connections |
| NPT | Industrial and North American applications |
| NPTF | Dry-seal threaded connections |
| BSW | British mechanical applications |
| BSF | Fine British threads |
| BA | Precision mechanical applications |
| UNC | Unified coarse threads |
| UNF | Unified fine threads |
| UNEF | Unified extra-fine threads |
| PG | Electrical and cable applications |
Brass Grades and Surface Finishes
The choice of material may affect the compressibility of the parts, their mechanical properties and resistance to corrosion for the compression fitting. Precious Metal Industries has Brass 319, BS 249 and special brass alloys based upon customer requirements.
Surface finishing can be done as follows:
- Natural brass finish
Nickel plating
Tin coating
Customized surface coatings
The type of finish depends on the level of environmental exposure, how the component is intended to be used, requirements for corrosion resistance and technical specification requirements quoted by the customer.
Manufacturing Process
Maintaining dimensional control and batch-to-batch consistency is facilitated by controlling the manufacturing process. The overall production process consists of:
Raw Material Selection → Cutting → CNC/Automatic Turning → Drilling → Threading → Profiling → Deburring → Surface Finishing → Inspection → Packing
1. Raw Material Selection
Appropriate brass is picked based on the design and use of components.
2. Precision Machining
Brass rods are cut and are machined for external and internal profiles by automatic or CNC machines.
3. Threading and Tapping
Internal and external threads manufactured to the given international standard.
4. Deburring
Sharp edges and machining burrs are eliminated for better assembly quality and handling of the components.
5. Surface Finishing
Depending on the application, natural finishes, nickel or tin or other specified finishes may be applied.
6. Quality Inspection
Prior to dispatch critical dimensions and threads are checked.
Applications of Brass Compression Fittings
Brass compression fittings are employed in a wide variety of industries and equipment where the brass tube and pipe systems are compatible.
Common applications include:
- Plumbing systems
- Water distribution equipment
- Hydraulic systems
- Pneumatic equipment
- Instrumentation
- HVAC systems
- Industrial machinery
- Automotive assemblies
- Gas and fluid-handling systems.
- Process equipment
- Control panels and equipment
- OEM machinery
In the case of high pressure and other special uses, the design, material, sealing process and applicable standards of the fittings should be determined according to the operating conditions of the equipment.
Advantages of Brass Compression Fittings
- Strong Mechanical Connection
Compression fittings are made to give a safe mechanical joint between compatible tubes and parts when they are properly designed.
- Good Machinability
Brass is a material that is suitable for precision turning, drilling, tapping and threading, and can be used to manufacture complex fitting geometries efficiently.
- Corrosion Resistance
Brass offers useful corrosion resistance in many plumbing and industrial applications, but the ability of a particular brass alloy to resist corrosion will depend on the service conditions.
- Easy Installation
Typically, standard mechanical tools can be used to install compression fittings without welding.
- Reusable Connection
Depending on the design and application, compression connections can be disassembled for maintenance or replacement.
- Custom Manufacturing
Application specific components can be indicated by OEM customers in terms of dimensions, type of threads, material and finish
Brass Compression Fittings Customized
While standard fittings generally comply with dimensional and connection specifications for a specific piece of equipment, this may not always be the case. So customized compression fittings made of brass can be produced based on engineering drawings, samples or Cad.
The fitting profile, tube size, thread configuration, hex dimensions, overall length, internal geometry, the grade and treatment of the material may be customized. This is where custom manufacturing can be beneficial for OEMs, equipment manufacturers, distributors and industrial buyers that need repeat manufacturing.
Based on the customer’s technical requirement, the brass part can be developed by Precious Metal Industries and manufactured for its consistent production requirement.
