Important notes

  • Please allow minor measurement error due to manual measurement.
  • Color may differ slightly from pictures due to monitor variations.
  • BSP sizes are not related to the actual physical thread diameter of the fitting—refer to the size diagram to identify your fitting size.

Helpful guidance on threads and compatibility

  • Why is stainless steel magnetic? 304 stainless steel is generally non-magnetic or weakly magnetic. It can become slightly magnetic after high-temperature forging and processing due to crystal lattice distortion.
  • How to identify real 304 stainless steel: thread identification and material analysis methods are available; chemical composition analysis or 304 stainless steel testing can confirm authenticity.
  • How to measure thread correctly: use appropriate tools and reference standards; note that different thread standards exist (NPT, BSP, Metric) and not all are interchangeable.

Usage tips and installation notes

  • Designed for easy and convenient installation with secure sealing when paired with compatible BSP/BSPT fittings.
  • Suitable for water, oil, gas, and certain corrosive liquids in non-extreme environments; verify media compatibility for your application.
