| PA6 is Nylon 6; PA12 is Nylon 12. They have separate pressure, temperature and bend-radius rows. PA is a broad material label, not a complete series/order code. UN54D flame resistance is not a PA6/PA12 claim. Both grades: OD/ID 4/2.5, 6/4, 8/6, 10/7.5, 12/9 mm; wall 0.75, 1.00, 1.00, 1.25, 1.50 mm respectively. Published scope stops at OD 12 mm; no OD 16 mm, arbitrary ID or inch size inferred. | 4×2.5 mm is 200M (200 m/coil); all other published sizes 100M. Both grades: BU Blue, BK Black, GE Orange, N Clear, WH White, GN Green, R Red, Y Yellow. N means clear color, not an alternative material. No cut-length supply promise. | At OD 4/6/8/10/12 mm, PA6 working 3.5/3.0/2.0/2.0/2.0 MPa, burst 11/10/7/7/7 MPa. PA12 working 2.5/2.0/1.5/1.5/1.5 MPa, burst 7.5/7/5/5/5 MPa. Burst pressure is not an operating limit. Do not use one maximum pressure for every grade/size. Specification range PA6 −10 to 70°C, PA12 −40 to 70°C. Derating table: PA6 20/40/60°C =100/74/57%; PA12 20/30/50/60°C =100/83/75/64%. The source also prints higher-temperature derating points beyond the specification range; these do not extend the rated 70°C maximum. Confirm actual pressure-temperature duty; no 100°C rating inferred. |
