Pipe down over there!

Pipe sealant secures threads and joints

Pipe sealant is a great material you can use to fix the leaks that form at the threaded connections between your pipes. These pesky leaks can damage which can lead to considerable repair costs if they are not addressed in time.

What is pipe thread sealant?

Many pipe thread sealants were designed for industrial applications, but you can use them around your home as well. They are high-performing pipe thread compounds that prevent leaks at the threaded connections joining pipes, even under harsh conditions.

Pipe thread sealants offer several benefits compared to the tapes and putties you can use to connect pipes. Premium products like Loctite 567 Thread Sealant and Loctite 577 prevent leaks because they do not shrink, crack, creep, or shred. They also seal to the burst strength of most piping systems while resisting vibration and shock loads. Lastly, these pipe sealants prevent galling and corrosion and eliminate seized assemblies.

Pipe sealants and their uses

You can use pipe sealants to stop substances like water from creeping through the threaded connections between pipes.

Not all pipe sealants are created equally, however. When selecting the right pipe thread compound for your project, you must ensure it can withstand the service or environmental temperature range it will be subject to. You also need to consider the thread type you are sealing. Some products, such as Loctite 567 Thread Sealant, are general-purpose instant pipe sealants that are suited for taper/taper threads. If you are working with straight/straight or taper/straight threads, however, you need a different product, such as Loctite 577. Also make sure your pipe thread sealant is suited for the materials you are working with. The manufacturer’s instructions will tell you which materials your product can bond.

How to use pipe sealants

Selecting the proper pipe sealant is the first step in any DIY pipe-sealing job. Once you have done that, follow these steps to get rid of leaks.

Get ready. Gather the parts you want to seal and your pipe sealant. Wear gloves to protect your hands.

Clean and prepare all external and internal surfaces. Clean and degrease the surfaces (with special cleaner, if necessary) and let them dry. If the materials to be bonded are inactive metals or the cure speed is not fast enough, you can spray an activator on the surfaces to prepare them.

Check it out: your pipe sealant manufacturer may also sell cleaners and activators.

Apply a bead of pipe sealant all around the leading male thread (360 degrees), leaving the first thread free. If you are working with bigger threads, apply the pipe sealant to both the male and female threads.

Insert the male thread into the female thread. Screw the two pieces together, which also spreads the pipe sealant so it fills in any gaps. Tighten them as appropriate using a pipe wrench or another suitable tool.

Clean-up. Use a cloth to wipe off any excess pipe sealant before it dries for a neat, clean joint. As always, wash your hands when you are finished.
