FAQ

What work fits NAICS 339991?
  • Supply of flange gaskets and spiral-wound seals manufactured to recognized material and dimensional standards for piping and pressure-retaining assemblies.
  • Production of custom-cut nonmetallic gaskets and sheet goods with specified thickness tolerances, durometer hardness, and temperature/chemical compatibility ratings for repair kits.
  • Manufacture of molded o-rings and elastomeric seals with batch testing, traceability, and certificates of conformance for maintenance spares.
  • Fabrication of equipment door seals and adhesive-backed profiles with installation-fit drawings for original equipment manufacturer replacement parts.
When is NAICS 339991 a weak fit?
  • General rubber product fabrication for consumer goods: scope produces consumer rubber articles without specified sealing performance tests or industrial tolerances required for sealing devices.
  • Machinery assembly and equipment integration: procurement is for assembled systems where seals are installed as part of overall equipment rather than the manufacturing of sealing components.
  • Precision metal structural fabrication: work prioritizes structural machining and load-bearing component tolerances outside gasket and sealing device manufacturing requirements.
What solicitation language points to NAICS 339991?
  • Technical specifications that list material compounds, hardness (durometer), dimensional tolerances, and approved leak or pressure test methods with pass/fail criteria.
  • Deliverables that require certificates of conformance, material traceability records, lot test reports, and serialized part numbers for replacement spares.
  • Evaluation criteria that weight manufacturing quality controls, evidence of a quality management system such as ISO certification, and production lead-time for batch orders.
