## What is the Yoke Screw in Scuba Diving?
The yoke screw is an essential part of any scuba diving regulator. It is the screw that connects the regulator to the scuba tank. The yoke screw is usually made of stainless steel or brass, and it has a threaded end that screws into the scuba tank’s valve. The other end of the yoke screw has a hole that allows air to flow from the tank into the regulator.
### How to Use the Yoke Screw
To use the yoke screw, simply screw it into the scuba tank’s valve until it is hand-tight. Do not overtighten the yoke screw, as this could damage the regulator or the tank.
Once the yoke screw is tight, you can open the tank’s valve and begin breathing from the regulator.
### Troubleshooting Yoke Screw Problems
If you are having trouble with your yoke screw, there are a few things you can check.
* **Make sure that the yoke screw is tight.** If the yoke screw is not tight, air may leak from the tank.
* **Check the O-ring on the yoke screw.** The O-ring is a small rubber washer that seals the connection between the yoke screw and the tank’s valve. If the O-ring is damaged or missing, air may leak from the tank.
* **Inspect the threads on the yoke screw and the tank’s valve.** If the threads are damaged, the yoke screw may not be able to seal properly.
### Yoke Screw Maintenance
The yoke screw is a relatively simple piece of equipment, but it is important to keep it clean and well-maintained.
* **Rinse the yoke screw with fresh water after each dive.** This will help to remove salt and other contaminants that can corrode the yoke screw.
* **Lubricate the O-ring on the yoke screw with silicone grease.** This will help to keep the O-ring in good condition and prevent it from drying out.
* **Inspect the yoke screw regularly for damage.** If you find any damage, replace the yoke screw immediately.
### Yoke Screw Safety
The yoke screw is a critical safety component of any scuba diving regulator. It is important to use the yoke screw correctly and to maintain it properly. By following these tips, you can help to ensure that your yoke screw is always in good working condition and that you can dive safely.
## Additional Information
In addition to the information above, here are some additional details about yoke screws:
* **Yoke screws are available in different sizes.** The most common size is the DIN/INT yoke screw, which fits both DIN and INT scuba tanks.
* **Yoke screws can be made of different materials.** Stainless steel yoke screws are the most common, but brass yoke screws are also available.
* **Yoke screws are relatively inexpensive.** You can expect to pay around $10-$20 for a new yoke screw.
If you have any questions about yoke screws, be sure to ask your dive instructor or a qualified scuba technician.
