From a specification
to a clear quotation.
A useful supply discussion starts with the essentials: the component, the quantity and the destination. Use these checkpoints to structure your enquiry.
Define the configuration
Specify tubing OD and ID, roll length and colour. For cylinders, include bore, stroke, mounting, connection thread and any drawing revision.
Build the quantity mix
List rolls by specification or cylinders by model. PU tubing can be combined across sizes to reach a total of 100 rolls.
State the destination
Include your country, city or port and requested delivery basis, so the quotation can define which charges are included.
Review before ordering
Agree specifications, packaging, payment, lead time and delivery terms in writing before placing an order.
BUYING GUIDE / BUILD YOUR ORDER
Make the first
enquiry count.
From a distributor replenishment list to an OEM bill of materials, start with the details that determine your quotation.
A mixed-size order
Combine sizes to suit your stock requirements. The 100-roll minimum applies to the total PU tubing order.
Start with your BOM
Send tube sizes, cylinder model codes, drawings and quantities. Identify any dimensions or material requirements that must match.
Identify the existing part
Share a clear marking photo and measurements. For tubing, include both outside and inside diameter.
ILLUSTRATIVE MIX / 100 ROLLS

An example to help build your enquiry. Change the mix to suit your requirements.

- 20 rolls 10 × 6.5 mm · 100 m / roll
Before you
compare prices.
Compare the same size, roll length and delivery basis. A price per roll alone is not enough when roll lengths differ.
What does 6 × 4 mm mean?
6 mm outside diameter and 4 mm inside diameter. The listed roll length for this size is 200 metres. Share the marking on your current tube if you are unsure.
Can I mix sizes to reach the minimum?
Yes. PU tubing orders start at 100 rolls in total and can include different listed sizes. Include the roll quantity for each size in your enquiry.
What operating details should I provide?
Include working pressure, temperature, fluid or gas, routing space and the fitting connection. Suitability and final specifications should be confirmed for your application before ordering.
Does a quotation include international shipping?
Check the delivery basis stated in the quotation. For an FOB request, specify the preferred Chinese loading port. Freight, duties and destination charges must be considered separately unless expressly included.
How are lead time and payment agreed?
Lead time, colour availability, packing and payment terms are confirmed for the requested order. Send your required delivery date with the size list.
CHUAINA / CYLINDER SELECTION
Start with the right specification.
Bore & stroke
Send the bore diameter and required travel in millimetres, together with your model code.
Mounting & ports
Include mounting dimensions, thread type and rod-end details. A drawing helps identify the configuration.
Operating requirements
Tell us the operating pressure, temperature, magnetic sensor requirements and quantity.
