Hercules ProPoxy 20 epoxy putty for plumbing repair

This two-part epoxy putty comes in a 4 oz tube and is designed for plumbing repairs on ceramic, glass, masonry, metal and wood. It is NSF/ANSI 61 certified and paintable once cured. The gray putty suits professional and DIY users needing a durable seal.

Check surface compatibility

The putty bonds to ceramic, glass, masonry, metal and wood; confirm your repair surface is listed. It performs between 40 and 300 degrees F, so verify the service environment stays within those limits. Working time and full cure are both 20 minutes, so plan the job accordingly.

Hand-kneadable tube format with sandable.

The tube packaging allows mixing by hand without separate tools, reducing mess on site. Once cured the epoxy can be sanded and painted to match surrounding surfaces. NSF/ANSI 61 certification confirms suitability for potable water contact.

Questions about this item

Does the 4 oz tube include any mixing tools or applicators, or must they be purchased separately?

The 4 oz tube contains the two-part epoxy putty only; no mixing sticks, gloves or applicators are supplied.

When should I choose the 4 oz ProPoxy 20 tube instead of a larger container?

Choose the 4 oz tube for small plumbing repairs or occasional jobs where a larger quantity would harden before use.

What does the 20-minute full cure time mean for a repair on a metal pipe?

After mixing, the putty reaches full strength in 20 minutes, so the repaired metal pipe can be pressure-tested or returned to service within that window.
