A laminated nylon air brake tubing is formed from outer and inner layers of nylon 11 or nylon 12 with inner layers of nylon 6. The nylon 6 and nylon 11 or 12 layers are adhered together by a tie layer. The tie layer is preferably a nylon 6-12 or an anhydride modified polyolefin. The air brake tubing has improved high temperature strength and low temperature impact resistance characteristics.
