JT3200T EATON Coupler for external

Product  Description：

The EATON Quick Disconnect (QD) Coupler for external applications is a mechanical device designed to rapidly connect and disconnect fluid lines (hydraulic, pneumatic, or fuel) without the need for tools, while minimizing fluid spillage and air inclusion. It consists of two mating halves, the coupler (female) and the nipple (male). When connected, internal valving mechanisms (such as poppet valves or flat-face valves) open to allow fluid flow. When disconnected, these valves automatically close to seal both ends of the line, ensuring a safe and clean operation. These couplers are built with high-strength materials, such as steel, stainless steel, or specialized alloys, to withstand high operating pressures and harsh external environments, providing a highly reliable, leak-free connection point between a fixed system and an external tool or hose assembly.

Product Parameters

The specific parameters depend on the coupler series (e.g., Aeroquip or Hansen brands) and the intended fluid, but key characteristics include:

• Operating Pressure: Often ranges from $50 \text{ psig}$ up to $5,000 \text{ psig}$ ($350 \text{ bar}$), depending on the application requirement.

• Flow Rate: Measured in Gallons Per Minute (GPM) or liters per minute ($L/min$), with values varying from less than $1 \text{ GPM}$ up to $175 \text{ GPM}$ or more.

• Size/Port Size: Available in various sizes, typically $1/4 \text{ inch}$ to $2 \text{ inches}$ or greater, with threads such as NPT, BSPP, or SAE.

• Seal Material: Includes materials like Buna-N (Nitrile), Viton (FKM), or PTFE, selected based on the fluid compatibility and temperature requirements.

• Temperature Range: Standard couplings operate within a range such as $-40^{\circ}\text{C}$ to $+120^{\circ}\text{C}$.

• Coupling Style: Options include Poppet, Ball Latch, Threaded, or Flat Face (for minimal spillage).

Product Advantages

EATON's external couplers offer several distinct advantages in industrial and mobile applications. They provide quick and easy connection and disconnection, significantly reducing maintenance time and improving operational efficiency. The advanced sealing mechanisms ensure minimal fluid spillage (non-spill/flat-face designs), which is critical for environmental protection and worker safety. They are designed for high durability and reliability, built to withstand high cycle rates, pressure spikes, and mechanical abuse typical of external use. Many models also feature safety interlocks or self-locking sleeves to prevent accidental disconnection under pressure, enhancing system security. Furthermore, EATON offers wide fluid compatibility through different seal and material options.

Important Considerations (Precautions)

Proper use and maintenance of the external coupler are essential for safety and longevity. Users must always verify that the coupler's pressure rating meets or exceeds the maximum system operating pressure to prevent catastrophic failure. It is crucial to clean the mating surfaces of both the coupler and the nipple before connection to prevent the ingress of dirt and contaminants into the fluid system. The coupler must be used only with fluids compatible with its internal seal and body materials. Finally, never attempt to connect or disconnect couplers under full system pressure unless the specific model is explicitly designed and rated for 'connect under pressure' capability, as this can cause component damage and pose a serious safety hazard.

Product Applications

EATON Couplers for external use are indispensable in a diverse range of industries where components or fluid lines must be frequently or temporarily connected. These include:

• Construction and Agriculture: Used on heavy equipment (excavators, tractors) for quickly attaching and detaching hydraulic tools and implements.

• Mobile Hydraulics: Employed in municipal vehicles, snow plows, and dump trucks for rapid connection of external auxiliary systems.

• Manufacturing and Industrial Automation: Utilized for temporary connections of cooling lines, testing rigs, or pneumatic tools in a plant environment.

• Aerospace and Ground Fueling: Specialized non-spill couplers are used for transferring aviation fuels or cryogenic cooling fluids in sensitive environments.

• Oil and Gas: Used for connecting high-pressure lines on drilling equipment or subsea tools.
