Joining and Sealing Materials and Components

Test and certify joining and sealing products for use in plastic piping systems for potable and non-potable water.

NSF provides global certification services for manufacturers of joining and sealing materials and components, including solvent cements, primers, lubricants, gasket materials and thread sealants.

Whether your products are used for drinking water systems or non-potable end-use applications, NSF provides rigorous testing services at our on-site laboratories to ensure they meet state and regional plumbing code standards.

Certify Drinking Water Products to NSF/ANSI 14 and NSF/ANSI/CAN 61

NSF offers expertise in both NSF/ANSI 14 and NSF/ANSI/CAN 61, which are both necessary for market access and regulatory approval.

Certification to NSF/ANSI 14 addresses product performance and includes testing to a normative product specification, like ASTM or CSA standards. Products are also held to in-plant quality control requirements to ensure continuous compliance over time.

Our joining and sealing product performance testing includes:

  • Gasket materials (ASTM F477)
  • CPVC solvent cements (ASTM F493, CSA B137.6)
  • PVC solvent cements (ASTM D2564, CSA B137.3, CSA B181.2)
  • ABS solvent cements (ASTM D2235, CSA B181.1)
  • Primers (ASTM F656)

An NSF/ANSI/CAN 61 evaluation addresses the health effects of your joining and sealing products, which is critical for all products intended for drinking water systems. All major model plumbing codes require that potable water products comply with NSF/ANSI/CAN 61.
