Brass Male-Female 90-Degree Elbow Fitting

NINGXING Brass Male-Female 90-Degree Elbow Fitting is designed to create a 90-degree change in pipe direction while connecting male and female threaded interfaces. The compact elbow structure helps simplify piping layouts in confined spaces and can be used with compatible valves, pipes, pumps, and equipment.

Made from brass, the fitting offers good mechanical strength, corrosion resistance, and machining performance. BSPT, BSPP/G, NPT, and UNF thread options are available, with nickel-plated finishes provided for applications requiring additional surface protection.

Thread Configuration

The male-to-female threaded structure allows the fitting to connect components with different connection directions without additional pipe bending. This is useful for equipment installations where the pipe needs to turn immediately after leaving a valve, wall outlet, or machine port.

NINGXING can supply different thread sizes and combinations according to the equipment interface. Buyers should confirm both the nominal size and thread standard because BSPT, BSPP/G, and NPT threads are not interchangeable even when their nominal dimensions are similar.

Flow Direction

The 90-degree geometry changes the pipeline direction within a compact space and can help reduce unnecessary pipe bends. The internal passage is machined to maintain a relatively smooth flow path, while the brass body provides the mechanical strength required for routine water, air, and oil service.

For systems involving higher pressure, elevated temperature, aggressive chemicals, refrigerants, steam, or other special media, the actual pressure-temperature rating and material compatibility should be confirmed for the selected specification.

Installation Requirements

Before installation, inspect the mating threads and make sure they are clean and undamaged. Apply an appropriate thread sealant or PTFE tape when required by the thread type and application. Start threading by hand to prevent cross-threading, then complete the connection with a suitable wrench.

Do not use excessive tightening force to compensate for damaged or mismatched threads. Over-tightening may deform the fitting or damage the sealing area. After installation, perform a leakage or pressure test before the system is placed into service.

Field Applications

1. Automation Equipment

A large automotive component factory used these elbows on a production line where pneumatic tubing had to turn within a limited installation space. The 90-degree connection reduced the need for additional straight fittings and tubing bends, helping simplify the layout and reduce potential leakage points.

2. HVAC Systems

In a central air-conditioning installation, the piping needed to change from vertical to horizontal direction inside a narrow ceiling space. Using a threaded elbow avoided additional pipe-bending work and allowed the installer to complete the connection without hot work.

3. Household Plumbing

A homeowner used a 1/2-inch brass elbow when modifying a kitchen water line to connect the wall outlet to a water purification system. The threaded connection allowed the pipe direction to be changed without rebuilding the original pipeline.

Technical Data

Size Reference

Dimensions are for reference. Customized sizes and thread combinations are available.

Service Conditions

A Brass Male-Female 90-Degree Elbow Fitting should be selected according to the actual service conditions rather than size alone. Pressure, temperature, fluid type, thread standard, seal material, and installation method can all affect connection performance.

The stated pressure range of approximately 1.0-6.9 MPa is a reference range and is not applicable to every size or configuration. Allowable pressure generally decreases as operating temperature increases. Customers requiring a specific pressure-temperature rating should confirm the exact model before ordering.

For drinking-water systems, RoHS compliance does not mean drinking-water certification. If the fitting will contact potable water, the required lead-free brass grade and local drinking-water certification should be specified separately.

For natural gas or fuel systems, a general-purpose brass fitting should not automatically be considered suitable for every gas installation. The applicable gas standard, certification, sealing method, pressure rating, and local installation code must be confirmed before use.

Quality Control

NINGXING manages production under an ISO 9001:2015 quality management system. Brass material preparation, forging, CNC machining, thread processing, surface treatment, and final inspection are controlled throughout production.

Dimensional inspection, thread gauges, leakage testing, and pressure testing can be arranged according to product specification and customer requirements. CE and RoHS compliance is available for applicable product configurations.

Custom Supply

NINGXING supports OEM and ODM orders for distributors, plumbing suppliers, equipment manufacturers, and engineering projects. Customization can include thread standards, male/female thread combinations, dimensions, nickel plating, logos, and packaging.

Standard sizes are available for bulk purchasing, while drawings or physical samples can be provided for non-standard development. This allows customers to match the fitting to existing equipment interfaces without redesigning the entire piping system.

FAQ

How do I choose the correct model?

Confirm the connection size, male/female orientation, thread standard, pipe type, working pressure, temperature, and fluid. If the existing interface is unclear, provide a drawing or product photo for technical confirmation.

Can BSP and NPT threads be connected together?

They should not be treated as directly interchangeable. BSPT/BSPP and NPT have different thread profiles and specifications. A compatible adapter or correctly specified fitting should be used.

What sealant should be used?

The choice depends on the thread type and application. PTFE tape or a suitable thread sealant can be used where required. The sealing method should also be compatible with the transported medium and operating temperature.

Is it suitable for gas applications?

Not automatically. Gas service requires confirmation of the fitting's material, pressure rating, sealing method, certification, and compliance with the local gas installation requirements.

Can NINGXING provide custom sizes?

Yes. Custom thread combinations, dimensions, surface finishes, logos, and packaging are available for OEM and ODM projects.

What certifications are available?

NINGXING operates under ISO 9001:2015 quality management requirements, with applicable products available with CE and RoHS compliance documentation.
