PUN-12X2-SW

What is this plastic tubing used for?

This tubing is intended for pneumatic installations carrying compressed air. It is a practical choice for routing air between push-in fittings, valves, cylinders and other pneumatic components where a 12 mm outside diameter tube is required.

What are the tube dimensions?

The tubing has an outside diameter of 12 mm and an inside diameter of 8 mm. These dimensions are important when matching the tube to compatible push-in pneumatic connections.

Which fittings is it designed to work with?

It is designed for push-in connectors that accept 12 mm outside diameter tubing. When selecting mating fittings, the outside diameter is the key size to check.

What material is the tubing made from?

The tube is made from TPE-U (PU), an ester-based material. This gives it the flexibility expected from pneumatic tubing while remaining suitable for general industrial compressed air applications.

What colour is the tubing?

This version is black, making it a useful option where a darker tube finish is preferred for machine builds or panel routing.

What pressure range can it handle?

For the complete temperature range, the operating pressure is -0.95 bar to 7 bar. The temperature-dependent operating pressure range is -0.95 bar to 10 bar. As with any pneumatic tube selection, the actual working condition should be checked against the installation temperature.

What temperature range is it suitable for?

The stated ambient temperature range is -35 °C to 60 °C. This makes it suitable for a wide range of industrial pneumatic environments, provided the overall system conditions remain within specification.

Can it be used in energy chains?

Yes. The tubing is stated as suitable for energy chains, which can be useful where repeated movement or guided cable-and-tube routing is part of the application.

What is the minimum bend radius?

The minimum bend radius is 33 mm, while the flow-relevant bend radius is 62 mm. In practice, keeping bends as gentle as possible helps maintain airflow and reduces the chance of restricting the tube.

What operating medium is it intended for?

It is intended for compressed air in accordance with ISO 8573-1:2010 [7:-:-]. That makes it suitable for standard pneumatic compressed air duties where the air quality matches the stated requirement.

Is the tubing RoHS compliant?

Yes. The tubing is listed as RoHS compliant.

Does it have any material or installation notes to consider?

Yes. The tubing is ester-based TPE-U, and it should only be installed in contact with cables whose sheathing is free of phosphoric acid esters. Otherwise, the tubing may become damaged. If you are referencing the exact item, this applies to PUN-12X2-SW.

Does the tubing have any fire classification information?

Yes. The material fire test rating is UL94 HB, which provides a recognised reference point for the tubing material.

Is there any information on surface compatibility for paint shop or sensitive processes?

Yes. The tubing is listed as LABS (PWIS) conforming to VDMA 24364-B2-L, which may be relevant in environments where paint-wetting impairment substances are a concern.

How much does the tubing weigh per metre?

The stated product weight is 0.0767 kg per metre. This can be helpful when estimating total installed weight for longer runs.
