Choosing nylon air line usually comes down to line size, length, pressure, and where the hose has to fit. This comparison covers two lengths of 1/4-inch DOT air line, one 3/8-inch DOT air line, and one larger PA11-6 flexible tube, with listed prices from $18.98 to $380.15.
Quick take
- The 50 ft 1/4-inch PA12 DOT line at $18.98 is the shortest 1/4-inch option and the lowest listed price.
- The 100 ft 1/4-inch PA12 DOT line at $37.49 gives you 30.5 meters of the same 1/4-inch size.
- The 100 ft 3/8-inch PA12 DOT line at $71.15 is the only 3/8-inch product here and is listed for up to 800 PSI.
- The 50 m Polyamide PA11-6 tube at $380.15 is the large-diameter flexible option, with an OD of 14mm and ID of 10mm.

Product notes
100 FT 1/4 DOT Air Line 1/4\" PA12 Nylon Pneumatic Tubing 30.5 Meter 1/4 Inch OD
If you need a continuous 100 ft of 1/4-inch line, this black PA12 roll is the direct choice. At $37.49, it covers the same 1/4-inch size as the 50 ft product but in one 100 ft / 30.5 m roll. The line is rated for use from vacuum to 500 PSI and -40°F to +248°F, matching the shorter 1/4-inch option. The longer roll is useful when you want to avoid splicing two 50 ft pieces together. The limitation is that if your run really only needs 50 ft, you pay for 100 ft of material you won't use.
50 FT 1/4 Pneumatic Tubing 1/4\" PA12 Nylon DOT Air Line SAE J844 DOT Air Hose 15
This is the lowest listed price in the comparison at $18.98, and it is the shortest 1/4-inch roll here. It comes as a 50 ft black PA12 nylon air line with a 1/4-inch OD, and its listed working range matches the other 1/4-inch line: vacuum to 500 PSI and -40°F to +248°F. If 50 ft is all you need for a simple run, this is the leanest way to get it. The limitation is length: once your route grows past 50 ft, you would need multiple pieces, which means extra joints and more total work.
100 FT 3/8 Pneumatic Tubing 3/8\" PA12 Nylon DOT Air Line SAE J844 DOT Air Hos
For a 3/8-inch line, this is the only product in the set at that outer diameter. It sells for $71.15 and includes a 100 ft 3/8-inch DOT air hose in black PA12 nylon. It is listed for use from vacuum to 800 PSI, which is higher than the 500 PSI figure on the 1/4-inch lines. That makes it a good match when the fitting or flow demand moves you out of 1/4-inch tubing. The trade-off is bulk: a 100 ft roll at 1.31 kg is more material to handle and store than the lighter 1/4-inch options.
Polyamide PA11-6 Flexible Nylon Tube Hose Pneumatic Air Line Tubing ID 2MM-17MM
This $380.15 product is not another DOT spool; it is a 50 m flexible PA11-6 nylon tube with an outer diameter of 14mm and an inner diameter of 10mm. It is listed as non-toxic, odorless, and pressure resistant, with an operating range of -30°C to 120°C. The application guidance recommends using an air storage tank, cooler, or filter when working with compressor output, because long-term direct use of hot compressor air can cause bulging or bursting. That points it toward automated equipment rather than a basic 1/4-inch whip. The higher listed price and larger 14mm/10mm dimensions make it a poor fit for a standard small pneumatic tubing setup.
Final recommendation by use case
For a straightforward 1/4-inch line, pick the 50 ft 1/4 Pneumatic Tubing at $18.98 if 50 ft is enough, or move to the 100 ft 1/4 DOT Air Line at $37.49 when you need the extra length. For a 3/8-inch line with a higher pressure range, the 100 ft 3/8 Pneumatic Tubing at $71.15 is the only 3/8-inch option in this comparison. For a larger flexible PA11 tube, the 50 m Polyamide PA11-6 at $380.15 is the product to look at, but it comes with guidance to route it through a storage tank, cooler, or filter instead of connecting it directly to a hot compressor outlet for long-term service.
