PA6 and PA12 tubing for vehicle
and mobile-equipment fluid and air lines
Review PA6 and PA12 nylon tubing for vehicle and mobile-equipment lines: identify the installation and circuit, then confirm the exact medium, temperature, pressure, fittings and drawing. The supplied data sheets list compressed air, oils, antifreeze and, for the stated models, fuels; polyether tubing is reviewed for air and low-pressure lubricating-oil connections. Brake and fuel lines are reviewed individually.
Scope note: Brake and fuel lines are reviewed individually.
QUICK SELECTION
Four details to define before a supplier review
Confirm the installation and operating conditions first. Certificate scope and sample acceptance are reviewed separately for the supplied model.
1. Location and motion
Vehicle installation, fixed and moving sections, nearby heat sources and vibration.
2. Medium and pressure
The medium (for example air, water or oil), working and peak pressure, and temperature range for each circuit.
3. Drawing and dimensions
Drawing revision, OD × ID, tolerances, and length or formed-route requirements.
4. Certificates and samples
The certificate scope the supplier must show, and the sample acceptance requirements.
Define where and how the tube will be used
Location and motion
Map the vehicle installation: mark fixed and moving sections, nearby heat sources, vibration exposure, protection and access for inspection or replacement. Identify the exact function of each tube on the drawing.
Medium and conditions
For each circuit, list the medium, working and peak pressure, temperature range and environmental exposure. State the applicable approval or customer standard before requesting a candidate model.
Drawing and dimensions
Send the drawing revision, OD × ID and tolerances, length or formed-route requirements, fitting interfaces and identification rules. Mark which dimensions and documents are mandatory for sample acceptance.
From requirements to a confirmed specification
01
Review the stated certificate scope
When comparing automotive tubing suppliers, check the original IATF 16949 certificate scope and validity alongside the proposed model documents, drawing requirements and sample acceptance plan.
02
Agree the acceptance requirements
Discuss sample evaluation, dimensional checks, identification, batch information and the documents required with delivery.
03
Confirm a sample
Agree dimensions, fittings and acceptance criteria before the order.
CANDIDATE PRODUCT FAMILIES
Compare product information
PA6 Nylon Tubing
Primary candidate: data-sheet media include compressed air, lubricating and mineral oil, fuels and ethylene-glycol antifreeze; confirm the exact fluid, temperature, pressure and fittings for the selected model.
View specifications →
PA12 Nylon Tubing
Primary candidate: data-sheet media include compressed air, mineral and hydraulic oil, diesel, petrol and antifreeze; review its own model data rather than transferring PA6 values to the same nominal size.
View specifications →
Polyether Tubing
Conditional candidate: data-sheet scope is air, industrial water, cleaning liquids and low-pressure lubricating oil; confirm the material designation and the oil against the actual service conditions.
View specifications →Vehicle tubing specification questions
Can nylon tubing be used for oil and fuel lines?
The PA6 and PA12 data sheets list oils and antifreeze, and fuels (PA6) or diesel and petrol (PA12), with the exact service conditions confirmed per line. Confirm the material designation, the fluid and its temperature, the pressure and the fittings.
Does IATF 16949 certify a tube for my vehicle circuit?
The management-system certificate describes its certified organization and scope. Each circuit is matched to a tube individually. Review the original certificate alongside the exact model documents and your project requirements.
Can I specify this tubing for brake or fuel lines?
Brake and fuel lines are reviewed individually. Such requests require the precise circuit, model, applicable standards and relevant test or approval evidence before a supply recommendation can be made.
What should a vehicle tubing sample review include?
Agree dimensions and tolerances, fitting interfaces, identification, required functional tests and acceptance criteria using the current drawing revision. Record the approved model and required batch or delivery documents for repeat orders.
Prepare your project inquiry
Send the vehicle circuit and intended function, drawing revision, medium, pressure and temperature, OD × ID, fitting details, quantity and mandatory standards. List the sample tests and delivery documents needed for approval.
