Does Duct Seal Putty Harden?

Duct seal putty is a malleable and flexible compound that is used to seal duct openings against drafts, dust, moisture, and noise. It also protects terminal boxes, headers, and bushings from corrosive elements and dampens switch panel noise. The putty is easily spread over holes and voids and will not harden or form skin under normal conditions. Duct sealant is primarily used to block air movement, moisture, and dust.

It can also be used to block noise and protect areas with electrical connections or to ensure that outlets and switches are safe from nearby water sources. However, it is not suitable for sealing threaded or unthreaded water supply pipes, which suffer from water pressure as water flows through them. Plumbers can use duct sealant when working with an appliance such as a washing machine, refrigerator, or dishwasher. The putty will remain malleable and flexible for years without hardening or drying out. Plumbing putty can also be used to seal faucets during pipe installation. Duct seal putty is an essential tool for any plumber or homeowner looking to protect their home from drafts, dust, moisture, and noise.

It is easy to apply and will remain malleable and flexible for years without hardening or drying out. It can also be used to protect electrical connections and outlets from water damage. Additionally, it can be used to seal faucets during pipe installation. In conclusion, duct seal putty does not harden under normal conditions. It remains malleable and flexible for years without hardening or drying out.

This makes it an ideal choice for sealing ducts, protecting electrical connections, and sealing faucets during pipe installation.
