What is Plumber’s Putty?
Plumber’s putty is a soft, pliable, clay-like substance designed to create a watertight seal around plumbing fixtures, especially where water is involved. It’s typically made from clay, linseed oil, caulking agents, and other ingredients that allow it to stay flexible and seal gaps effectively.
Key features of plumber’s putty:
-
- Flexible & Malleable: Can be worked into any shape needed.
-
- Water-Resistant Seal: Prevents leaks effectively when applied correctly.
-
- Removable & Reusable: Does not harden permanently, allowing adjustments if necessary.
-
- Easy to Apply: No special tools other than hands.
Note: It is not suitable for high-temperature areas or locations exposed to constant water pressure such as under the water heater or in pressurized pipes. For such applications, a silicone sealant might be preferable.
