Our technicians monitor wall thickness, bend radius, and surface finish in real time. Continuous in-process checks ensure every batch meets specs. Annual capacity exceeds 1.2 million pieces. At AIFN, production is repeatable, traceable, and reliable—from raw tube to finished fitting. See our lines in action.

We meet ASTM, ASME, and ISO standards, with full traceability via laser marking. No deviation is accepted. From wall thickness to surface finish, nothing is left to chance. The result? Zero-defect fittings for harsh environments. Trust AIFN – quality guaranteed.
