Primer for PVC and CPVC pipe

This purple-tinted P-68 primer prepares PVC and CPVC pipe surfaces for solvent-cement bonding. The 32 oz can supplies enough primer for multiple joints on residential or light-commercial plumbing work. It meets ASTM F656 and carries NSF and UPC listings for code compliance. Professional plumbers and DIY installers use it to ensure reliable, leak-free connections.

Can packaging and cured colour

The metal can reseals to keep primer fresh between jobs, and the purple cure colour lets inspectors verify that primer was applied before cement. Brush-on application is straightforward, and the formula works with standard PVC and CPVC solvent cements. No special tools or mixing are required, so the product fits normal plumbing routines.

Standards and usage limits

ASTM F656 defines the performance baseline this primer satisfies, and the NSF and UPC marks confirm it passes health and safety review for potable-water systems. The primer is not intended for other pipe materials such as ABS or polyethylene, and it does not replace the solvent cement itself. Always follow local code requirements for joint preparation and cure times.
