Unique-Bargains Nylon Tube 3mm ID x 5mm OD 3.0 m Black
PA6 nylon tube for fluid transfer and air-brake systems, 3.0 m long with 3 mm ID and 5 mm OD
- Excellent flexibility with a small bending radius for tight routing
- PA6 nylon handles -40 to 120 temperature range
- 3mm ID x 5mm OD suits air brake and fluid lines
- 1mm wall thickness keeps pressure loss minimal
- 0 m (9.8 ft) length supplied as a single piece
What this tube is and who needs it
Unique-Bargains supplies a 3.0 m length of black PA6 nylon tube with a 3 mm inside diameter and a 5 mm outside diameter. It is built for hydraulic brake lines, power steering circuits and general fluid transfer on light trucks, passenger cars, forklifts, cranes and marine equipment.
How to fit it and what to watch
The tube's small bending radius and excellent flexibility let it follow tight routing without kinking, while the 1 mm wall resists shock and vibration. Cut cleanly with a sharp knife, deburr the ends and push fully into compatible push-to-connect or compression fittings; avoid over-tightening metal ferrules which can crush the thin .03" wall.
Capacity, temperature range and limits
Rated for continuous service from -40 to 120 °C, the nylon maintains constant hardness and low permeability across that span. The 9.8 ft coil handles typical pneumatic and light hydraulic pressures with minimal pressure loss, but it is not suited for high-pressure hydraulic systems or fuel lines that demand specialised barrier tubing.

Questions about this item
How can I confirm the 3 mm inner diameter and 1 mm wall thickness are correct after uncoiling the 3.0 m length?
Measure the bore with a caliper at several points along the 3.0 m coil; it should read 3 mm inside and 5 mm outside, giving a 1 mm wall.
The package lists only the nylon tube — do I need to buy fittings or clamps separately for a pneumatic brake line?
The box contains 1 x 3.0 m PA6 nylon tube; barbed or push-to-connect fittings and retaining clips for brake or fluid systems are not included.
Should I choose this 3 mm ID × 5 mm OD size or a different diameter for a -40 to 120 °C air brake circuit?
Select the 3 mm ID × 5 mm OD tube when the system calls for that exact bore and 1 mm wall; other diameters will not seal properly in the same fittings.
