The bottom line: this 200 ft coil is best for users who require a DOT-compliant, high-pressure nylon line that resists corrosion and temperature extremes. The reviewer found the tubing's proven pressure rating and reinforced construction to be the strongest reasons to choose it for semi truck, trailer, RV, or industrial air systems.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDOT-compliant PA12 material:\u003c\/strong\u003e The polyamide 12 construction meets D.O.T.
