What types of certifications or approvals do 1-1/4 rigid coupling typically hold?


1-1/4″ rigid couplings typically hold certifications or approvals from recognized organizations that validate their compliance with industry standards and regulations.

Some common certifications or approvals for 1-1/4″ rigid couplings may include:

  1. American National Standards Institute (ANSI):
    • ANSI/UL 213: Standard for Flexible Metal Conduit
    • ANSI/UL 514B: Standard for Conduit, Tubing, and Cable Fittings
  2. Underwriters Laboratories (UL):
    • UL Listed: Indicates that the rigid coupling has been tested and certified by UL to meet specific safety and performance standards.
  3. Canadian Standards Association (CSA):
    • CSA Certified: Indicates that the rigid coupling complies with relevant Canadian standards and regulations.
  4. National Sanitation Foundation (NSF):
    • NSF/ANSI 61: Standard for Drinking Water System Components – Health Effects
  5. FM Approvals (Factory Mutual):
    • FM Approved: Indicates that the rigid coupling has been tested and approved by FM to meet specific performance and quality standards.
  6. American Water Works Association (AWWA):
    • AWWA C606: Standard for Grooved and Shouldered Joints
  7. European Conformity (CE):
    • CE Mark: Indicates that the rigid coupling complies with European Union directives and regulations for health, safety, and environmental protection.
  8. ISO Certification:
    • ISO 9001: Quality Management System Certification

These certifications or approvals demonstrate that the 1-1/4″ rigid couplings have undergone testing and evaluation by independent organizations to ensure compliance with relevant standards, specifications, and performance criteria. They provide assurance to customers, contractors, and regulatory authorities that the rigid couplings meet quality, safety, and reliability requirements for use in various applications, including plumbing, HVAC, fire protection, and industrial piping systems.

It’s essential to verify the specific certifications or approvals held by a particular brand or model of 1-1/4″ rigid coupling to ensure compliance with applicable standards and regulations in your region or industry. Additionally, adherence to local building codes and regulations may also be required for the installation and use of rigid couplings in specific applications or environments.
