Brass Three-Way Female Thread Connector

The Brass Three-WayFemale Thread Connector has three female-threaded ports for dividing, combining or redirecting pipelines. It can connect with male-threaded pipes, valves, adapters and other components, while allowing removal for inspection or replacement.

The forged brass body provides mechanical strength, corrosion resistance and dimensional stability. Under suitable conditions, the fitting supports pressures up to 1.6 MPa and temperatures from -20℃ to +150℃.

Product Comparison

Selecting the correct fitting configuration helps avoid unnecessary adapters, installation space and potential leakage points. The following comparison can help buyers choose between a three-way fitting, elbow, cross and straight connector.

For a system that needs one inlet and two outlets, the T-shaped three-way configuration is generally more suitable than combining an elbow with additional connectors. An elbow is preferable when the only requirement is to change direction. A four-way fitting should be selected when the system requires four connection directions or a cross-shaped distribution point.

Thread Compatibility

Available thread standards include NPT, BSP/G, PT/R and ZG. Buyers should confirm the required thread type, nominal size and whether the existing system uses tapered or parallel threads before ordering. Correct thread matching helps prevent leakage, thread damage and installation problems.

When replacing an existing fitting, buyers should check the actual thread standard, port orientation, nominal size and available installation space. Nominal pipe sizes from different standards may not provide interchangeable connections.

Sealing and Installation

Clean the male thread before installation and apply suitable PTFE tape or thread sealant according to the medium and system requirements. Tighten the fitting by hand first, then use a wrench for final tightening. Avoid excessive force, which may damage the threads or deform the fitting.

Gas, oil and other critical systems should be inspected and pressure-tested after installation. The sealing method should be compatible with the transported medium, operating temperature and pressure.

Material and Surface Options

The Brass Three-Way Female Thread Connector is made from brass for reliable strength, machinability and corrosion resistance. Surface options include polishing, sandblasting and nickel plating. A wrenching area on the body helps installers tighten the fitting safely.

The brass body is suitable for many water, air, oil and industrial fluid applications. For seawater, oxygen, refrigerants, medical gases or other specialized media, the complete material, sealant and system specification should be reviewed before use.

Applications

The Brass Three-Way Female Thread Connector is suitable for plumbing distribution, HVAC water circuits, pneumatic equipment, gas equipment and industrial fluid systems. Compatible media may include water, air, oil, gas, steam, seawater, oxygen, refrigerants and medical gases, subject to the required material, sealing method, pressure rating and local regulations.

The three-way configuration is especially useful where a main line must supply two branches, where two lines must converge, or where a compact connection point is needed inside equipment.

Project Applications and Cases

1. Commercial HVAC Project

A commercial complex covering approximately 80,000 square meters used more than 860 DN25 and DN32 fittings in its central air-conditioning cooling-water system. The system passed the water-pressure test without leakage, and accurate threads improved installation efficiency by more than 30%.

2. Gas Equipment Production

A gas equipment manufacturer producing approximately 500,000 units annually used 1/4" and 3/8" fittings for pipeline connections and airtightness testing. Customized packaging and stable supply helped reduce downtime caused by thread slipping by approximately 70%.

3. Overseas Water Project

A Middle Eastern water engineering company used the fittings in seawater desalination and water-supply projects requiring corrosion resistance and reliable sealing. Supported by available inventory, the order was delivered efficiently, and the customer later added NINGXING to its global supplier list.

Specifications and Ordering

Regular sizes range from DN15 to DN50, with other dimensions available for suitable orders. Thread options include NPT, BSP/G, PT/R and ZG. The stated working pressure is up to 1.6 MPa, and the temperature range is -20℃ to +150℃.

When requesting a quotation, buyers should provide the size, thread standard, quantity, surface treatment, packaging requirements and intended application. Buyers should also indicate whether they require a three-way configuration, elbow, cross, straight connector or reducer so that the correct fitting can be supplied.

Applicable standards may include GB/T 11618 and ASME B16.11, depending on the product configuration.

Quality and Certifications

NINGXING follows an ISO9001:2015-certified quality management system. Products are available with CE and RoHS compliance. Inspection may include dimensional checks, thread gauge verification, pressure testing, leakage testing, surface inspection and packaging inspection.

Water-pressure testing can be performed at up to four times the maximum working pressure, while corrosion resistance can be evaluated through salt-spray testing.

Stock and OEM Supply

Regular specifications are maintained in stock where possible to support distributors, maintenance companies and project buyers. NINGXING has production capacity exceeding 80,000 pieces per month.

OEM customization is available for suitable quantities, including thread standards, dimensions, surface treatment, brand marking and packaging. Buyers can also request support in selecting the appropriate fitting configuration for a specific pipeline layout.

FAQ

What is this Brass Three-Way Female Thread Connector used for?

It is used to divide, combine or redirect three threaded pipelines in plumbing, HVAC, pneumatic, gas and industrial systems.

How is a three-way fitting different from an elbow?

A three-way fitting has three ports and is used for branching or combining pipelines. An elbow has two ports and is mainly used to change the direction of a pipeline.

When should I choose a four-way fitting?

Choose a four-way fitting when the system requires four connection directions or a cross-shaped distribution point. For a single inlet with two branch outlets, a three-way fitting is usually more suitable.

Which thread standards are available?

NPT, BSP/G, PT/R and ZG thread options are available.

What sizes are available?

Common sizes range from DN15 to DN50. Custom sizes can be discussed according to production requirements.

What pressure and temperature can it handle?

The stated working pressure is up to 1.6 MPa, with a temperature range of -20℃ to +150℃. Actual limits depend on size, thread type, medium and operating conditions.

Can it be used for gas?

Yes, provided that the material, thread configuration, sealing method and pressure rating meet the requirements of the gas system. Installation and testing should follow local regulations.

How should it be sealed?

Clean the male thread and apply suitable PTFE tape or thread sealant. Tighten carefully and check for leakage after installation.

Is OEM customization available?

Yes. Customization can include dimensions, thread standards, surface treatment, brand marking and packaging.

Are regular specifications in stock?

Regular specifications are available from stock where possible. Buyers should confirm availability before placing urgent orders.

Buyer Checklist

Before purchasing, confirm the connection size, thread standard, pressure, temperature, medium and installation requirements. For replacement projects, check the existing fitting dimensions and thread type rather than relying only on nominal pipe size.

Also confirm the required fitting configuration. Select a three-way fitting for branching or combining three pipelines, an elbow for a directional change, a four-way fitting for four-direction distribution, a straight connector for inline joining and a reducer for connecting different pipe sizes.

For bulk orders, also confirm inspection requirements, packaging, labeling and delivery schedules. Buyers can provide the required size, thread standard, fitting type and quantity to receive a specification and quotation.
