The Burkle StopCock angled is a polypropylene liquid dispensing tap designed for controlled dispensing from canisters, barrels, and other compatible containers with a G 3/4" connection. Its angled, rotatable spout directs liquid toward the receiving container while the reduced nozzle helps dispense into narrow bottle openings.
The 0525-1000 StopCock uses a 3/4" internal-thread cap nut for connection to compatible containers and features a rotatable discharge spout designed to reduce residual dripping. The tapered outlet has a 6 mm outside diameter, making it useful when liquid needs to be directed into smaller openings.
Burkle specifies media-contacting parts made from PP, PE and PTFE. The StopCock is designed for laboratory, production, chemical logistics, food-related, and other compatible liquid-handling applications where convenient container dispensing is required.
The angled outlet can be positioned to direct liquid where it is needed. Burkle specifically describes the rotatable spout as helping prevent unwanted dripping after dispensing, which can make liquid transfer cleaner and more controlled.
The outlet has a 6 mm outside diameter and a reduced nozzle design. This is particularly useful when dispensing into bottles or other receiving containers with small openings, where a larger outlet could make positioning more difficult.
The StopCock connects to compatible containers using a G 3/4" internal-thread cap nut. Burkle states that its StopCock discharge cocks fit containers with G 3/4" connection threads, while thread adapters can be used for connection to a wider range of compatible containers.
Burkle specifies PP, PE and PTFE for the media-contacting components. Material compatibility should still be checked against the specific liquid being dispensed before use.
The StopCock provides a simple way to dispense liquid directly from a storage container without transferring the entire container or using a separate dispensing vessel. This can be useful where containers are repeatedly accessed during laboratory or production workflows.

Burkle's North American catalogue specifies that the StopCock design is pressure-resistant up to 2 bar at 20 °C under the manufacturer's stated test configuration, without the discharge bracket and grommet. This pressure specification should not be interpreted as a universal pressure rating for every installation or application.
| Application | How the StopCock Helps |
|---|---|
| Laboratory liquid dispensing | Allows liquids to be dispensed directly from compatible storage containers without transferring the entire container. |
| Filling narrow-mouth bottles | The reduced 6 mm spout helps direct liquid into smaller openings. |
| Chemical logistics | Provides a convenient dispensing point for compatible liquids stored in containers and barrels. |
| Food and beverage production | Provides manual liquid dispensing from compatible containers in production and handling workflows. |
| Research and production facilities | Provides repeatable access to liquids stored in compatible containers without requiring a separate dispensing assembly. |
Burkle offers several accessories for the StopCock system. These can extend the outlet configuration or allow liquid to be directed through tubing.
| Accessory | Burkle Part Number | Purpose |
|---|---|---|
| Hose nozzle, 4 mm | 0525-1304 | Connects compatible tubing to the StopCock. |
| Hose nozzle, 6 mm | 0525-1306 | Connects compatible tubing to the StopCock. |
| Hose nozzle, 8 mm | 0525-1308 | Connects compatible tubing to the StopCock. |
| Hose nozzle, 10 mm | 0525-1310 | Connects compatible tubing to the StopCock. |
| Hose nozzle, 12 mm | 0525-1312 | Connects compatible tubing to the StopCock. |
| Hose nozzle, 16 mm | 0525-1316 | Connects compatible tubing to the StopCock. |
| Discharge angle | 0525-1400 | Angled adapter for directing the StopCock outlet. |
The StopCock is designed around a G 3/4" container connection. Burkle states that its StopCock discharge cocks fit containers with G 3/4" connection threads, while thread adapters can extend compatibility to additional containers.
Check the container connection before ordering.
The 0525-1000 uses a G 3/4" internal-thread cap nut. Confirm that your container or adapter provides the appropriate mating G 3/4" connection.
Do not select the product based only on the apparent physical size of the fitting. G-thread connections are standardized pipe-thread designations, and the connection type must match the mating component.
Not suitable for crystallizing substances. Burkle specifically identifies this limitation for the StopCock range.
Verify chemical compatibility between the liquid and the media-contacting PP, PE and PTFE materials before use. Burkle provides a chemical-resistance resource for evaluating compatibility with specific substances.
For pressurized systems, remain within the manufacturer's specified operating conditions. Burkle's catalogue states a pressure resistance of up to 2 bar at 20 °C under the stated configuration; this should not be treated as a general pressure rating for every installation.
