Brass Ferrule Compression Male Thread Connector

Made from high-strength brass, Brass Ferrule Compression Male Thread Connector uses a ferrule compression structure to grip the tube and create a reliable metal-to-metal seal. NINGXING provides direct factory supply, OEM customization, bulk pricing, and technical support. Products are manufactured under an ISO 9001:2015 quality management system, with CE and RoHS compliance available.

Tube Connection Structure

The fitting consists of a body, ferrule, and compression nut. When the nut is tightened, the ferrule is pressed against the internal cone of the body, gripping the tube and forming a secure mechanical seal.

This design does not require welding or tube threading, making it suitable for systems exposed to vibration, pressure fluctuations, and temperature changes. It also allows the tube to be disconnected during maintenance.

Pressure and Temperature Range

The Brass Ferrule Compression Male Thread Connector can support pressures up to 550 bar under suitable conditions. The actual rating depends on tube outside diameter, wall thickness, material, fitting size, and operating temperature.

The recommended temperature range is approximately -40°C to +250°C. For high-pressure applications, customers should confirm the tube specification, thread type, operating medium, and system conditions before ordering.

Thread Matching

Available thread standards include:

BSPP: Parallel thread for straight-thread equipment ports.

BSPT: Tapered BSP thread for compatible tapered interfaces.

NPT: American tapered pipe thread for North American equipment and fluid systems.

Customers should confirm both the thread standard and nominal size. Drawings, samples, or interface dimensions can be provided for technical verification.

Material Compatibility

High-quality brass provides mechanical strength, corrosion resistance, and accurate thread machining. The fitting is suitable for compatible copper tubing, nylon tubing, and selected semi-rigid plastic tubing.

Tube material, hardness, and wall thickness must be checked before selection. Very soft plastic tubing may require an internal tube insert. For aggressive chemicals, customers should provide the fluid composition, concentration, temperature, and pressure for compatibility evaluation.

Installation and Reassembly

Cut the tube square, remove burrs, clean the surface, and check for damage. Insert the tube fully into the fitting body, then tighten the compression nut according to the recommended installation procedure.

Avoid excessive tightening, which may deform the tube or fitting components. The connection can be disassembled for maintenance. Before reuse, inspect the ferrule, tube end, and sealing surfaces. For critical applications, replacing the ferrule during reassembly is recommended.

Application Cases

Automotive Automation

A Chinese automotive component manufacturer experienced compressed-air leakage from pneumatic fittings on an automated welding robot production line. Repeated robot movement and vibration caused conventional fittings to loosen.

The customer replaced the original connections with the Brass Ferrule Compression Male Thread Connector during scheduled maintenance. After replacement, air leakage was reduced by more than 90%, system pressure became more stable, and unplanned downtime decreased.

Mold Cooling

A precision injection molding factory used copper tubing in mold cooling circuits. Welded connections made mold replacement and piping modifications time-consuming.

After switching to compression fittings, the customer no longer needed welding or tube expansion. Modification time was reduced from approximately 2 days to 4 hours, and the tubes could be disconnected and reinstalled when required. The equipment manager commented: "This fitting solved a major problem for us. Installation is very convenient, and workers can learn how to use it in about 10 minutes."

Instrumentation Systems

Petrochemical instrumentation systems often contain many small-diameter tube connections in limited spaces. Welding can make installation and maintenance more difficult.

The Brass Ferrule Compression Male Thread Connector provides a compact, welding-free connection for instrument valves, control components, and analytical equipment. BSPP, BSPT, and NPT options support different equipment interfaces.

Standard Dimensions

The following dimensions represent common BSPP straight male thread specifications. Non-standard dimensions and other thread configurations are available according to customer drawings.

Note: These are standard references for BSPP straight male-thread fittings. Other thread standards and dimensions can be manufactured according to application requirements.

Quality Control

NINGXING controls brass material selection, CNC machining, thread production, assembly, and inspection. Key checks include thread accuracy, concentricity, sealing surfaces, internal cone quality, and ferrule dimensions.

Products are manufactured under an ISO 9001:2015 quality management system. CE and RoHS documentation is available for applicable products and configurations.

OEM and Bulk Supply

NINGXING supplies fittings directly to distributors, equipment manufacturers, hydraulic suppliers, and industrial system integrators.

Customers can request quotations by providing the tube size, thread standard, quantity, and application medium. OEM projects can include custom dimensions, thread combinations, tube specifications, packaging, labeling, and documentation requirements.

FAQ

What tubes can be used?

Compatible copper tubes, nylon tubes, and selected semi-rigid plastic tubes can be used. Tube outside diameter, wall thickness, hardness, and material must be confirmed before selection.

Does installation require welding?

No. The fitting is assembled mechanically with the body, ferrule, and compression nut.

Can the fitting be reused?

It can be disassembled and reused if all components remain undamaged. For critical applications, a new ferrule is recommended during reassembly.

What is the maximum pressure?

The maximum working pressure can reach 550 bar under suitable conditions. The actual rating depends on fitting size, tube specifications, temperature, and system conditions.

Which thread should I choose?

Choose BSPP for parallel-thread interfaces, BSPT for tapered BSP interfaces, and NPT for American tapered pipe-thread interfaces. NINGXING can help identify unclear threads from drawings, samples, or dimensions.

Is customization available?

Yes. NINGXING supports non-standard dimensions, special thread combinations, tube configurations, and OEM production based on drawings or samples.

Can I buy directly from the factory?

Yes. Direct factory supply, samples, technical confirmation, and volume quotations are available for distributors, equipment manufacturers, engineering companies, and bulk buyers.
