Brass Three-Way Male Thread Connector

This Brass Three-Way Male Thread Connector is designed for systems requiring three external threaded outlets. It can connect valves, pumps, manifolds, control blocks, pipe assemblies and equipment ports.

The T-shaped structure can divide one supply line into two branches, combine two inlet lines, or provide a compact branch connection on machinery and control equipment. Its forged brass body offers a balance of machinability, mechanical strength and corrosion resistance.

Dimensional Reference

The following dimensions are for preliminary selection. Final dimensions should be confirmed according to the selected thread standard, drawing and tolerance requirements.

A refers to the center-to-end length of the main port, B to the branch port length, C to the approximate width across the two main ports and D to the hexagonal wrenching width. Dimensions may vary according to thread standard, machining tolerance and surface treatment.

Thread Matching and Installation

NINGXING supplies NPT, BSP/G, PT/R and ZG thread options. The selected thread must match the female-threaded component in profile, size and thread direction. Incompatible threads may cause leakage, cross-threading or damage to the mating component. For mixed-origin systems, sample connection or thread-gauge verification is recommended.

Before installation, clean the threads and check compatibility. Apply suitable PTFE tape or thread sealant, start the connection by hand and tighten it with a wrench on the hexagonal section. Avoid excessive torque. After installation, inspect the connection and perform pressure testing when required.

For gas, refrigerant, oxygen, medical gas and other controlled systems, the sealant and installation method must be compatible with the medium and comply with applicable regulations.

Material and Surface Treatment

The Brass Three-Way Male Thread Connector is made from forged brass, providing dimensional stability and reliable threaded connections. Available surface options include polished brass, sandblasted brass and nickel-plated brass.

For seawater, oxygen, refrigerants or medical gases, the material grade, cleaning process, sealant and compliance requirements should be confirmed before production.

Maintenance and Applications

The threaded design allows removal and replacement with standard tools after the system has been isolated and depressurized. Typical uses include plumbing and HVAC water systems, pneumatic control equipment, gas appliances and equipment, industrial oil and fluid lines, equipment manifolds, pump and valve assemblies, machine tool connections, pipeline repair and maintenance, and threaded component replacement.

Compatible media may include water, air, oil, gas, steam, seawater, oxygen, refrigerants and medical gases when the complete system is designed and tested for the selected conditions.

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 cooling-water system. The system passed the water-pressure test without leakage, while 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. The order was supported by available inventory, and the customer later added NINGXING to its global supplier list.

Product Specifications

The final pressure and temperature ratings depend on the selected size, thread configuration, medium and system design.

Quality Control and Documentation

NINGXING operates an ISO9001:2015-certified quality management system. CE and RoHS documentation can be supplied according to the product specification and destination market.

Inspection may include material verification, dimensional inspection, thread-gauge inspection, surface inspection, pressure testing, leakage testing, salt-spray testing when specified, and packaging inspection. Water-pressure testing can be performed at up to four times the maximum working pressure when required.

OEM, Packaging and Delivery

OEM customization may include thread standard, size, port length, port spacing, hex width, thread length, surface treatment, brand marking, labeling and packaging. Drawings or samples are recommended for customized dimensions.

Regular specifications are available from stock where possible. Monthly production exceeding 80,000 pieces supports distributor replenishment, maintenance orders and larger projects. Standard, neutral or customized export packaging can be arranged.

FAQ

What type of connection does this Brass Three-Way Male Thread Connector provide?

It provides three external threaded connections for female-threaded pipes, valves, adapters, manifolds or equipment ports.

Which thread standards are available?

NPT, BSP/G, PT/R and ZG thread standards are available according to the target market and equipment requirements.

What sizes are available?

Standard sizes range from DN15 to DN50. Other sizes may be available for suitable OEM or project orders.

Can the dimensions be customized?

Yes. Port spacing, branch length, overall length, hex width and effective thread length can be discussed according to production feasibility and order quantity.

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 the selected specification and application.

Can it be used in gas equipment?

Yes, when the material, thread standard, sealing method, pressure rating and testing requirements meet the system specifications and local regulations.

How should it be installed?

Clean the threads, confirm compatibility, apply suitable sealant, start tightening by hand and finish with a wrench on the hexagonal section. Avoid excessive torque.

Are regular products available from stock?

Regular specifications are available from stock where possible. Current inventory should be confirmed before urgent purchasing.

Does NINGXING provide OEM packaging?

Yes. Standard, neutral and customized export packaging can be arranged, including labels, carton markings and private-brand packaging.

Buyer Checklist

Before ordering, confirm the nominal size, thread standard, port orientation, port lengths, hex width, installation clearance, operating pressure, temperature, transported medium, surface treatment, marking, inspection requirements, packaging and delivery date.

For replacement projects, provide photos, samples or drawings when possible. Equipment manufacturers should confirm the mating female-threaded port and installation clearance before final approval. For bulk orders, also confirm sample approval, dimensional tolerances, thread-gauge requirements, inspection reports and shipment documentation.
