Weld-On 13994 P-70 Purple Primer PVC/CPVC 32 oz

SKU CH-MPDY-DVGKM

Purple primer for PVC and CPVC pipe, 32 oz can, meets ASTM F656 and NSF standards

  • Purple colour lets you verify coverage on pipe joints
  • Meets ASTM F656 and NSF standards for code compliance
  • UPC listed for easy inspection and traceability
  • 32 oz can supplies enough primer for multiple fittings
  • Formulated specifically for PVC and CPVC adhesive systems

What this primer is and who uses it

Weld-On P-70 Purple Primer prepares PVC and CPVC pipe surfaces for solvent cement bonding. The 32 oz can supplies enough fluid for multiple residential or light-commercial plumbing joints. It meets ASTM F656 and carries NSF and UPC listings for code-compliant installations.

Verify pipe material and local restrictions before

Confirm that the piping system uses PVC or CPVC; the primer is not formulated for ABS or other plastics. Check that your jurisdiction accepts the listed standards, as the product is restricted from sale in certain states. Ensure the adhesive you plan to use is compatible with a purple primer base.

Behaviour during extended joint preparation

The purple tint remains visible on the pipe surface, letting installers confirm coverage across long runs without re-coating. The fluid maintains consistent viscosity throughout the 32 oz container, so the last joint receives the same surface penetration as the first. Cured joints meet the referenced standards when the correct cement is applied within the recommended open time.

Questions about this item

Does the 32 oz can include the CPVC cement or must that be purchased separately?

The can contains only the P-70 purple primer; the matching CPVC cement is sold separately.

When should I choose the P-70 series instead of another Weld-On primer?

Select the P-70 series when the job calls for a purple primer that meets ASTM F656 and carries NSF and UPC listings.

What does the ASTM F656 listing mean once the primer is on the pipe?

It confirms the primer conforms to the standard for PVC and CPVC solvent-cement primers, ensuring proper joint preparation.
