Identify the oil or grease, line pressure, temperature, tube dimensions and fittings before comparing models, and confirm each against the model data. [Discuss your project →]() [View product range →]() **Scope note:** Media in the supplied data sheets are a starting point; confirm the exact oil, additives, temperature and pressure for each line. Each line is reviewed individually. ![Illustrative CNC machine tool with a lubrication manifold and nylon lines]() QUICK SELECTION ## Four details to prepare before comparing models Gather these from the lubrication layout or oil circuit. They narrow the candidate families; the final model is confirmed against the listed specifications. ### 1. Medium Lubricating, mineral or hydraulic oil, or grease: name it with any additives. ### 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 line, or a moving machine axis or tool that needs bend space. ## Start with the lubrication layout ### Machine lubrication lines For centralised or point lubrication on a machine tool or production line, list each lube point, the oil type, line length, tube OD and ID, fitting type and **working pressure**. Mark which lines are fixed and which move with an axis. ### Vehicle and mobile-equipment oil lines For oil lines on mobile or off-highway equipment, state the medium, **operating temperature** range, vibration and routing, and the fittings. Mark heat sources and abrasion points on the drawing. ### High-pressure and transfer lines Where line pressure is high, review the composite construction separately: identify the model, layer construction, medium and fittings, and confirm the **working pressure** for that model at the **operating temperature**. ## From layout to a confirmed specification 01 ### Define the lubrication layout Send the lube-point list or oil circuit with tube lengths, OD and ID. 02 ### Review candidate materials Compare product data for the oil, pressure and temperature of each line. 03 ### Confirm a sample Agree dimensions, fittings and acceptance criteria before the order. CANDIDATE PRODUCT FAMILIES ## Compare product information ![PA6 nylon tubing product]() ### PA6 Nylon Tubing Data-sheet media include lubricating oil, mineral oil, fuels and antifreeze: compare PA6 dimensions, pressure data and fittings against the line, and confirm the exact oil. [View specifications →]() ![PA12 nylon tubing product]() ### PA12 Nylon Tubing Data-sheet media include mineral and hydraulic oil, diesel, petrol and antifreeze: review its own model data rather than carrying PA6 values across to the same nominal size. [View specifications →]() ![High-pressure composite tubing product]() ### High-Pressure Composite Tubing Data-sheet scope covers lubrication and oil transfer, spraying and demanding fluid systems: identify the model, construction, medium and fittings, and confirm **working pressure** for that model. [View specifications →]() ## Lubrication and oil-line tubing questions ### Which nylon tubing should I consider for lubrication lines? Compare PA6 and PA12 models against the same OD × ID, oil, temperature and pressure. The supplied data sheets list lubricating and mineral oil for PA6 and mineral and hydraulic oil for PA12; confirm each against the actual lubricant and additives. Use the [PU versus nylon selection checklist]() to organize the comparison. ### What should I send for a lubrication or oil-line enquiry? Provide the lubrication layout or oil circuit, lubricant type, working and peak pressure, temperature, OD × ID, line lengths, fittings and quantity. The [tubing dimension guide]() explains OD, ID and **wall thickness**. ### Can PU tubing be used for oil lines? The PU data sheet covers compressed air, inert gases and vacuum circuits and does not recommend continuous long-term transfer of large quantities of lubricating oil. **Polyether tubing** lists low-pressure lubricating oil; confirm the model, pressure and oil before use. ### What is the difference between working pressure and burst pressure? **Working pressure** is the pressure a line may operate at, at a stated temperature. Burst pressure is a test value, not a working limit. Read the [working pressure and temperature review]() before specifying. ## Prepare your project inquiry Send the lubrication layout or oil circuit drawing, lubricant type, line pressure and temperature, OD × ID, line lengths, fitting details and quantities. Include any moving axes and a short layout sketch.
