PACKAGING / PRODUCTION MACHINERY
Tubing for packaging and production machinery
Specify tubing for packaging and production machinery by machine zone: valve-to-cylinder lines, pneumatic gripper connections and service replacement routes. Keep compressed-air circuits separate from any product-contact requirement.
Scope note: Compressed-air circuits are kept separate from any product-contact requirement.
QUICK SELECTION
Four details to prepare before comparing models
Gather these from the machine drawing and zone tube list. They narrow the candidate families; the final model is confirmed against the listed specifications.
1. Medium
Compressed air only, or any contact with the packaged medium or cleaning agents.
2. Tube OD × ID
Both dimensions, in mm, with tolerance if specified.
3. Pressure and temperature
Working pressure at the stated operating temperature.
4. Fixed or moving
Fixed route, or a moving gripper or actuator connection that needs bend space.
Start with the installation
Identify the pneumatic circuits
For each valve, actuator or pneumatic gripper connection, record the machine zone, circuit reference, OD × ID, fitting interface, cut length and quantity. Link the tube list to the current machine drawing.
Plan maintenance access
Mark tube routes around moving guards and service points. Record color identification, access for replacement and the installed length, then separate fixed cuts from connections whose reach changes during operation.
Define the working environment
List air pressure and quality, temperature, cleaning agents and exposure duration. If washdown or product contact is involved, state the exact requirement so the proposed grade and documents can be reviewed.
From layout to a confirmed specification
01
Define the route
Send a sketch, drawing or tubing list with inner and outer diameters.
02
Review candidate materials
Compare product data for the actual equipment conditions.
03
Confirm a sample
Agree dimensions, fittings and acceptance criteria before the order.
CANDIDATE PRODUCT FAMILIES
Compare product information
PU Tubing
PU candidate for specified air circuits: compare listed sizes with valve and actuator fittings, installed routes and the required cut list.

PA6 Nylon Tubing
PA6 candidate for the machine tube list: compare OD × ID and model data, and agree acceptance before substituting for the installed material.
View specifications →
PA12 Nylon Tubing
PA12 candidate: review its own model data rather than transferring a PA6 or PU specification to the same nominal size, and agree acceptance before substituting.

How should I specify pneumatic tubing for packaging machinery?
Use a zone-based tube list linked to the machine drawing. Include the valve or actuator reference, material, OD × ID, fitting type, cut length, color and quantity, then add air and environmental conditions for model review. PE or flame-retardant tubing can be reviewed where a circuit or environment requires it.
Does use on food packaging equipment mean food-contact approval?
No. A compressed-air circuit and a tube directly contacting the packaged medium are different requirements. Identify actual contact and the applicable standard; request supporting documents for the exact supplied model.
What should I check when replacing a tube on a packaging machine?
Record the installed specification, fittings, route and operating conditions. Compare the replacement model against that specification and agree any changes with the equipment owner. The receiving checklist supports dimensional and identification checks.
Can color identify the correct tube specification?
Use color as part of the machine’s identification scheme, alongside the material, model, dimensions and circuit reference. Pressure rating and material grade are set per model, regardless of color.
Prepare your application inquiry
Send the machine-zone tube list, circuit drawing, OD × ID, fitting types, cut lengths, color references and quantities. Add air conditions, cleaning exposure and any product-contact documentation requirement.
