Quick answer
To fix a shower head ball joint, first tighten the collar nut by hand, then check the rubber washer inside it. A worn or hard washer, or a cracked ball, is what usually makes the joint loose or leaky. A new swivel ball connector gives you a fresh seal and a smooth, tight swivel.
Free fix vs. permanent fix
Tighten, clean and reseat
- Hand-tighten the collar nut, then a quarter turn with a wrench and cloth
- Take the head off and wipe the ball and its seat
- Check the rubber washer for flat or cracked spots
- Soak mineral crust off in white vinegar, if the finish allows
How long it lasts: Weeks to months if the seal was only dirty or dry. A cracked ball or hardened washer starts leaking again.
A new metal swivel ball connector
A ball joint leaks when its seat wears out or the ball cracks. Cleaning only helps a dirty seal. A new connector screws onto the arm, takes the head on its far end, and replaces the worn joint in one go.
What to get: Metal swivel ball connector for a shower arm
How long it lasts: Years. A new seat and ball restore a tight swivel.

Why it happens
A worn or flat rubber washer
The washer seals the ball against its seat. Hot water and time make it hard, flat or cracked, so water slips past.
A loose collar nut
Heat cycles and pushing the head around can loosen the nut that holds the ball. A loose nut lets the ball wobble and drip.
Mineral buildup on the ball
Hard water leaves scale on the ball and seat. The scale scratches the seal and stops the ball sitting flush.
A cracked plastic ball or housing
Over-tightening or years of heat can crack a plastic ball. Once it cracks, no seal will hold, and the part has to be replaced.

Do these in order, starting with the simplest.
-
Find where it leaks
Tool used: Adjustable wrench and soft clothDry the joint with a towel, then run the shower and watch. Water at the arm connection means a thread or tape problem. Water at the ball means the seal.
-
Tighten the collar nut
Tool used: Adjustable wrench and soft clothHand-tighten the nut that holds the ball. If it still leaks, add a quarter turn with the wrench and a cloth under the jaws. Plastic nuts crack if you overtighten them.
-
Take it apart and clean
Tool used: White vinegar and old toothbrushUnscrew the head from the arm. Wipe the ball and seat, and soak scaled parts in white vinegar for 30 minutes. Scrub with an old toothbrush. Check the care guide first if the finish is brass or bronze, since vinegar can dull it.
-
Swap the washer
Tool used: Shower head rubber washersFit a new rubber washer the same size as the old one. A flat, hard or cracked washer is a common reason for a drip at the ball.

-
Re-tape the arm and reassemble
Tool used: Plumber's tapeWrap plumber's tape 3 to 4 times clockwise around the arm threads as you face the end, so it does not unwind. Screw the head on by hand until snug. If it still drips, fit a swivel ball connector between the arm and the head.

When free fixes aren't enough
If the washer is new and the joint still drips, the ball or its seat is damaged, and cleaning will not help. A swivel ball connector replaces that worn joint with a new seal. Check how your head attaches first. If the ball is built into the head and the housing is cracked, the head itself is the part to replace. If water leaks from the arm inside the wall, or the wall or ceiling is damp or stained, shut off the water and call a plumber.

Metal swivel ball connector for a shower arm

- Who it's for
- Anyone whose head wobbles or drips at the swivel and wants a fresh, adjustable joint.
- Honest downside

Which part is leaking? A 2-minute check
- Water at the arm and wall: redo the arm threads with plumber's tape, or check the arm itself.
- Water at the collar nut: tighten it, then check the washer.
- Drips from the face after the shower is off: that is usually trapped water draining out, not a joint leak.
- Water inside the wall or on the ceiling below: shut off the water and call a plumber.
What to skip
Silicone smeared on the ball joint
A dab of silicone or pipe sealant on the ball may stop a drip for a few days, but it stops the ball seating and makes the joint hard to adjust or take apart. Fix the washer or replace the connector instead.
