Black Nylon Pneumatic Tube 8mm ID × 10mm OD – 30m Coil | PA12 Air Line

Material Science

Why PA12 Outperforms Every Alternative

Not all nylon tube is equal. Polyamide 12 (PA12) sits at the top of the nylon hierarchy — absorbing less than 0.3% moisture compared to PA6's 9% and PA11's 1.9%. This matters in pneumatic systems: moisture absorption causes dimensional instability, pressure loss, and premature fitting failure. PA12 maintains its rated bore diameter and wall integrity across the full operating range, ensuring consistent flow and a reliable seal at every push-fit connection.

The black pigmentation is not cosmetic. Carbon-black UV stabilisation protects the polymer chain from photodegradation in exposed installations — outdoor compressor lines, vehicle undercarriage routing, and workshop environments with skylights or open bays. It also prevents light-induced oxidation of air system lubricants and inhibits biological growth in moisture-prone circuits.

Technical Performance

Engineered for Demanding Environments

• Working Pressure: 15 bar (217 PSI) at 20°C — with a 3:1 safety factor giving 45 bar minimum burst pressure
• Temperature Range: Continuous operation from −40°C to +80°C; handles cold-start conditions and heated workshop environments without embrittlement or softening
• Minimum Bend Radius: 40mm — routes cleanly through tight cable trays, conduit entries, and machine frames without kinking
• Wall Thickness: 1mm consistent throughout — ensures positive collet engagement in push-to-connect fittings and prevents blow-out under pressure cycling
• Abrasion Resistance: Shore D60–D65 hardness — resists wear from metal edges, cable ties, and high-movement routing without surface cracking
• Chemical Resistance: Resistant to mineral oils, hydraulic fluids, fuels, greases, and common workshop solvents — safe for use in vehicle maintenance and industrial environments
• Dimensional Tolerance: OD ±0.1mm, ID ±0.1mm — precision-controlled for consistent push-fit engagement across all major fitting brands

Applications

Where Professionals Specify This Tube

Installation

Fitting Compatibility & Installation Notes

This tube is dimensioned for direct use with all standard 8mm push-to-connect (push-fit) pneumatic fittings — straights, elbows, tees, crosses, bulkheads, and reducers. The 10mm OD and 1mm wall thickness provide the correct collet engagement depth for a leak-free, pull-resistant connection without additional preparation.

The 30m coil length is sufficient for most full workshop air line installations or multiple machine feeds from a single coil. Store unused tube coiled to prevent set and kinking. Minimum storage bend radius: 100mm.
