The BWU, BWD and BWUS Series are high pressure cooling system fittings designed for straight connections in demanding tubing applications. Manufactured with brass or nickel-plated brass bodies, these fittings provide a durable connection solution where mechanical strength, pressure resistance and stable sealing are important.
Available with NPT, BSPT, BSP and Metric threads, the fittings can be matched with PA11, PA12, PA6, PE and PU tubing. Their compact straight configuration helps create clean and efficient tubing layouts in cooling equipment, pneumatic machinery and industrial fluid or air circuits.
The BWU, BWD and BWUS Series are developed for applications that require a dependable straight connection between tubing and equipment ports. As cooling system fittings, they provide a practical way to organize tubing routes while maintaining a compact installation footprint. The push-in connection structure also helps simplify assembly and routine replacement compared with more complicated tubing connection methods.
All three series are available in a High Pressure Straight configuration, making them suitable for systems where tubing needs to pass directly between connection points without additional bends or branches.
The fittings use a brass or nickel-plated brass body, combining structural strength with improved surface protection. They are designed for compressed air, gas and vacuum service and operate within a temperature range of -20°C to +80°C.
Common specifications include:
● BWU Series: High Pressure Straight design for direct tubing connections.
● BWD Series: High Pressure Straight configuration for compact system layouts.
● BWUS Series: High Pressure Straight design for reliable high-pressure tubing connections.
● Working pressure: 0–20 bar
● Thread options: NPT, BSPT (PT/R), BSP and Metric
● Compatible tubing: PA11, PA12, PA6, PE and PU (98 Shore A)
● Recommended tubing tolerance: ±0.1 mm
These specifications allow the three series to cover different connection requirements while maintaining a consistent fitting platform.
These high pressure fittings can be used in cooling equipment, industrial automation, pneumatic machinery, air circuits and equipment requiring organized tubing connections. Their straight form is especially useful when the tubing route is already aligned with the threaded port.
For compact machinery, the BWU Series can provide a straightforward connection solution. The BWD and BWUS Series can be selected according to the equipment structure, tubing arrangement and fitting configuration required by the specific installation.
Installation requires the tubing to be cut cleanly and inserted fully into the fitting's push-in port. The threaded end should be matched with the equipment port before tightening to establish a secure connection.
Recommended installation practices include:
● Select the correct tubing outside diameter.
● Keep the tube end clean and square after cutting.
● Insert the tube fully into the fitting.
● Avoid excessive side loads or sharp bending near the connection.
● Verify pressure and temperature conditions before operation.
With a durable brass or nickel-plated body and multiple thread standards, the BWU, BWD and BWUS Series provide a practical range of straight connection options for cooling and industrial tubing systems.
