The Precise Alignment Stainless Steel Stub Ends are manufactured to MSS SP-43 Class A tight tolerances, delivering the dimensional accuracy required for precision piping systems. In applications where perfect flange alignment and consistent wall thickness are essential, these stub ends minimize installation stress and ensure reliable sealing performance.
Each fitting is CNC machined after forming to achieve precise control of the flange face, bore and outside diameter. This level of accuracy allows rapid bolt hole alignment with lap joint flanges and produces joints that are free from angular misalignment and gasket stress. Manufactured from SS304 and SS316L stainless steel, our precise alignment stub ends are the preferred choice for instrumentation lines, skid mounted packages and high integrity process systems where measurement accuracy and leak tightness matter.

Precision manufacturing requires precision measurement. Our inspection team uses calibrated vernier calipers, bore gauges and optical measuring instruments to verify every critical dimension against MSS SP-43 Class A requirements. Each fitting is individually checked for ovality, wall thickness variation and flange face squareness. The quality management system is certified to ISO 9001:2015, and we maintain complete records for lot traceability. With a dedicated CNC machining capability and 15 years of experience in precision pipe fittings, we consistently deliver tight tolerance stub ends for demanding projects in Europe, America and Asia.
