Product List

A hydraulic tee is a T-shaped fitting, which can connect three components to allow the fluid to pass freely within it. Hydraulic tee fitting is made of metal, which can be used in high-pressure environments to connect different hydraulic pipelines and allow the fluid to pass through in a relatively smooth manner. There are several types of hydraulic tee: equal tee, branch tee, run tee, and reducing tee. These types of tee fitting all have JIC, BSP, metric, ORFS, and NPT threads. Some tee has the same threads for all three, while some have different threads. Contact Topa to select the most suitable hydraulic tee fitting!

Female ports can be fixed or swivel-type to suit installation requirements

Sealing Methods

Depends on thread type; supports O-ring, metal-to-metal cone seal (JIC 37°), or flat-face O-ring seal (ORFS)

Materials

🔩 Carbon Steel (Zinc-Plated)

This is the most widely used material in industrial hydraulic systems. Carbon steel offers high strength, impact resistance, and cost-efficiency. The surface is zinc-plated to improve corrosion resistance.

Silver zinc plating – General protection for indoor or low-exposure systems

Yellow trivalent zinc plating – Enhanced protection with aesthetic visibility

🛡️ Stainless Steel (304 / 316 Grades)

304 Stainless Steel – Good corrosion resistance and cost-effective for general corrosive applications

316 Stainless Steel – Superior protection, especially in saltwater, acidic, or chlorinated environments

🟡 Brass

Brass offers excellent machinability, is naturally corrosion-resistant in fresh water, and is ideal for applications where frequent disassembly or field replacement is required.

Working Principle – How a Hydraulic Tee Adapter Functions

A hydraulic tee adapter serves as a critical junction point in fluid power systems. It features a T-shaped design with three openings: two aligned on a straight axis (run ports) and one branch port that intersects perpendicularly. Here’s how it works:

When hydraulic fluid enters the adapter from one run port, the internal passage directs the fluid in two possible directions—continuing through the second run port or diverting it through the branch port.

In practical systems, the tee fitting makes it possible to:

Share a main hydraulic line between two downstream components
Monitor pressure by connecting a sensor to the branch
Supply fluid to auxiliary tools or actuators from a single feed line

🔄 Flow Division

Tee adapters are commonly used to split hydraulic flow into two separate lines. For example, from one pump output, you can supply two hydraulic cylinders operating in tandem or independently. This ensures simultaneous operation or provides redundancy in system design.

🔁 Flow Collection

In reverse applications, tee adapters combine flows from two separate sources into one line. This can be useful for systems with dual pumps feeding a common return line or for synchronized hydraulic movements.

🔧 Adaptation

Tee fittings are not limited to fluid routing. They also serve as transition points between different thread types or sizes. For example, a branch port may have a smaller thread size for pressure gauges or different sealing type (e.g., JIC to NPT), allowing system customization without compromising flow integrity.

Working Pressure: Up to 6000 PSI (414 bar)

Topa tee adapters are rated for high-pressure hydraulic systems, with most standard carbon steel models supporting working pressures up to 6000 PSI, depending on size, thread type, and configuration.

Temperature Range: -40°C to +120°C

Minimum: -40°C (-40°F) – Suitable for outdoor, winter, or refrigeration-related environments

Maximum: +120°C (248°F) – Compatible with high-temperature fluid circuits, such as engine-driven hydraulic pumps or brake systems

Corrosion Resistance: 96+ Hours Salt Spray Tested

All Topa tee fittings undergo surface treatment to resist corrosion in harsh or humid environments. We conduct neutral salt spray tests (NSS) in accordance with ASTM B117 or ISO 9227, with results exceeding 96 hours of protection on.

Hydraulic Tee Adapter Types

Fixed Tee Adapter VS Swivel Tee Adapter

What Is a Fixed Tee Adapter?

Fixed Tee Adapters feature female ends that do not rotate. Once installed, the fitting stays in a fixed position. These are typically used where:

The hose or tube does not need to move after the connection

The operator has sufficient room for wrench access

The hydraulic circuit is stationary and stable

What Is a Swivel Tee Adapter?

Swivel Tee Adapters include at least one female swivel port, which allows the hose to rotate independently of the body during installation. This makes alignment much easier and helps reduce hose wear caused by torque or movement.

Branch Tee VS Run Tee

What Is a Branch Tee?

A Branch Tee (“Side Outlet Tee”) has:

Two run ports (the straight-through ports) of the same thread/gender

One branch port (the perpendicular side port) with a different thread/gender

Usage:

When you need to tap into an existing line with a sensor, valve, or smaller hose

For pressure gauge ports or signal line takeoffs

What Is a Run Tee?

A Run Tee (sometimes referred to as an Equal Tee) has:

One run port and the branch port share the same thread/gender

The remaining run port is different

Usage:

Used when connecting two different components inline and feeding a third from the branch

Helps in adapting systems with mixed thread sizes or orientations
