Electroplated Brass 90-Degree Elbow Fitting

The NINGXING Electroplated Brass 90-Degree Elbow Fitting is designed for 90° cable routing and protected conduit connections in electrical and industrial equipment. Made from brass with a nickel-plated surface, it provides good mechanical strength, corrosion resistance and wear resistance in demanding environments. M, PG, G and NPT thread options are available, with customized sizes supported. Selected configurations can achieve IP68 protection when correctly assembled with compatible sealing components. NINGXING manufactures under an ISO 9001:2015 quality management system, with CE and RoHS compliance available for applicable configurations.

Construction and Processing

The Electroplated Brass 90-Degree Elbow Fitting uses a brass body with nickel plating, NBR sealing components and a metal clamping structure. Forging and CNC machining help maintain dimensional consistency around the threaded and sealing areas, while automated electroplating provides a more uniform protective surface.

The standard temperature range is approximately -40℃ to +100℃, with short-term exposure up to +120℃ depending on the specific configuration. Actual performance depends on the sealing material, installation method and surrounding environment.

Thread and Protection Options

The fitting can be supplied with M, PG, G and NPT threads to match different equipment and conduit systems. Custom thread combinations and dimensions can also be produced from drawings or samples.

IP68 protection is configuration-dependent. The complete assembly, including the conduit, cable diameter, sealing ring and installation torque, must meet the relevant requirements. An IP68-rated fitting should not be assumed to provide IP68 protection when used with incompatible components.

Application Boundaries

This Electroplated Brass 90-Degree Elbow Fitting is primarily intended for electrical cable protection, control cabinets, automation equipment, machinery and other compatible installations. It should not be selected solely according to thread size.

For outdoor, high-humidity or salt-spray environments, the nickel-plated surface can improve corrosion resistance, but prolonged exposure to concentrated chemicals, strong acids, strong alkalis or highly corrosive media requires material compatibility verification.

The stated temperature range applies to the specified product configuration. NBR sealing components may have different temperature and chemical resistance limits from the brass body, so the lowest-rated component determines the practical operating range.

For hazardous areas, explosion-proof equipment or railway applications, additional application-specific certification may be required. CE and RoHS compliance do not automatically indicate explosion-proof, railway or other industry-specific approval.

Project Applications

1. Industrial Automation

A large automotive component factory needed cable conduits to turn through narrow gaps between densely arranged automation equipment. Straight fittings created excessive cable bending. After installing the Electroplated Brass 90-Degree Elbow Fitting, the cables could follow a more compact 90° route, improving installation efficiency and maintaining the required cable bending radius. The specified IP68 configuration also helped protect connections in an environment containing oil and dust.

2. Outdoor Control Cabinets

A municipal lighting control cabinet in a coastal city was exposed to humidity and salt spray. Conventional fittings developed corrosion after several months, affecting sealing performance. The customer changed to nickel-plated brass fittings, and after more than two years of operation, the connections remained functional and sealed under the reported operating conditions.

3. Rail Transit

For a metro tunnel signal-cable project, the cable conduits required multiple 90° changes before entering equipment cabinets. NINGXING supplied customized NPT-thread fittings for the project. The source material states that the supplied configuration passed EN 45545-2 requirements; project-specific certification should be confirmed for the exact model and batch before use.

Specifications

Installation Notes

Before installation, confirm the thread standard, conduit or cable diameter, sealing requirements and environmental conditions. The fitting should be correctly aligned and tightened according to the applicable installation requirements.

Do not use excessive tightening to compensate for damaged threads, incorrect component dimensions or poor alignment. Over-tightening may damage the thread, sealing ring or housing and can reduce the actual protection level.

Where IP68 protection is required, the complete connection should be checked after installation rather than assuming the fitting's nominal rating applies automatically to the finished assembly.

FAQ

What thread standards are available?

NINGXING supports M, PG, G and NPT thread standards, with customized specifications available for OEM projects.

Can the fitting achieve IP68?

Selected configurations can achieve IP68 when used with compatible cables or conduits, sealing components and correct installation. The protection level applies to the complete assembly rather than the metal body alone.

What is the operating temperature?

The standard reference range is -40℃ to +100℃, with short-term exposure up to +120℃ for applicable configurations. The actual limit should be confirmed according to the sealing material and product specification.

Is it suitable for outdoor installations?

It can be used in compatible outdoor electrical installations, including humid and salt-spray environments. For continuous exposure to strong chemicals or highly corrosive conditions, material and coating compatibility should be verified.

Does RoHS mean it is suitable for all electrical applications?

No. RoHS controls certain restricted substances but does not replace application-specific approvals. Hazardous-area, explosion-proof, railway or other regulated applications may require additional certification.

Can NINGXING provide customized fittings?

Yes. NINGXING supports customized thread standards, dimensions, angles and structural configurations based on drawings, samples or project requirements.
