How to Loosen Brass Fittings That Are Stuck

Brass fittings are tough and long-lasting, but they can get stuck over time. It might be because of rust, dirt, or simply being screwed on too tight. Don’t worry – there are easy ways to fix this without damaging the fitting. Here’s how you can loosen those stubborn brass fittings.

Before grabbing all your tools, remember that brass is softer than other metals. Start carefully so you don’t damage the fitting.

To loosen a stuck brass fitting, get these items:

• A wrench or adjustable spanner
• Penetrating oil (like WD-40)
• A heat source (such as a small torch or heat gun)
• A rag or cloth
• Gloves for safety
• Optional: Pliers, pipe wrench, or a rubber mallet for extra help

Sometimes the threads are stuck because of buildup or rust. Here’s how oil can help:

1. Spray or apply penetrating oil onto the threads of the fitting.
2. Let it sit for about 15-20 minutes. If it’s really stuck, leave it overnight.
3. Try turning the fitting with your wrench. If it’s still stuck, move on to the next step.

Heat can make the brass expand slightly, which helps loosen it:

1. Use a small torch or heat gun to warm the fitting evenly. Don’t overheat it.
2. Heat it for 1-2 minutes, then try turning it with your wrench. Remember to wear gloves to protect your hands.
3. If it’s still stuck, alternate between applying heat and oil. The heat helps the oil seep in better.

If the fitting is still stuck, you might need more force:

1. Attach a longer handle or a pipe to your wrench to give you extra leverage.
2. Be careful not to use too much force, as this could damage the fitting.
3. For a better grip, you can also use a pipe wrench or pliers.

A little vibration can help break the bond:

1. While holding the wrench, gently tap it with a rubber mallet.
2. The small shocks can help loosen rust or dirt inside the threads.

If none of the above works, you might need to replace the fitting:

1. Use a hacksaw or pipe cutter to carefully cut it out.
2. Clean the threads of the pipe before installing a new fitting.

After you’ve fixed or replaced the fitting, take steps to avoid this problem next time:

• Use Thread Tape: Wrap plumber’s tape around the threads before screwing the fitting in place. This makes it easier to loosen later.
• Don’t Over-Tighten: Tighten the fitting enough to seal it, but not so much that it’s hard to remove.
• Check Regularly: Inspect your fittings every now and then to catch any rust or buildup early.

Loosening a stuck brass fitting doesn’t have to be frustrating. With some oil, heat, and patience, you can get it moving again. Take your time, and remember to protect your fitting from getting stuck in the future. Good luck!
