## Product Summary

PHT pneumatic fittings are elbow throttle valve push-to-connect connectors designed for 90-degree tube-to-thread connection with adjustable airflow control in pneumatic systems.

Unlike standard elbow fittings, PHT integrates a flow control (throttle) mechanism, allowing precise regulation of air flow and actuator speed.

The elbow structure enables compact installation and efficient tube routing, while the built-in adjustment valve provides fine control over airflow.

Push-to-connect technology allows quick installation and easy tube removal without tools, improving system efficiency and maintenance convenience.

PHT fittings are available in multiple material options, enabling flexible selection based on corrosion resistance, strength, and working environments.

OEM and ODM customization services are available for thread types, materials, and branding requirements.

### Key Features

Integrated throttle valve for airflow control90° elbow structure for compact installationPush-to-connect quick connectionAdjustable speed control for pneumatic systemsOptional material: nickel-plated brass or stainless steelStable and leak-resistant sealing performance

### Applications

Pneumatic control systemsUsed for regulating airflow and controlling actuator speed

Industrial automation equipmentEnsures precise motion control in cylinders

Air distribution systemsProvides adjustable airflow control

Machinery and equipment pipingOptimizes system performance and efficiency

Automation motion control systemsIdeal for speed adjustment applications

### Product Function

PHT fittings are designed to connect pneumatic tubing to threaded ports while controlling airflow through an adjustable throttle mechanism.

By regulating the flow rate of compressed air, PHT fittings help control the speed of pneumatic actuators such as cylinders.

Compared with standard elbow fittings (PL / PLT), PHT adds flow control functionality, eliminating the need for separate speed control valves.

This simplifies system design and reduces component count in pneumatic circuits.
