Oil Stuffing Box Packing Rubbers
Stuffing Box Rubbers Designed With a Strong Seal
Used in oil, gas, agricultural and industrial applications, a stuffing box and the rubbers within provide a seal with a rod string that extends within a well for powering a pump. The actual box is a device for preventing the leaking of gases or liquids as the rod pumps through the well.
The rubbers inside, known as packing, are compressed around the moving shaft to help create a strong seal. We offer quality stuffing box rubbers at an affordable price and an even better delivery rate for your well-head packing needs.

What Is the Purpose of a Stuffing Box?
A stuffing box is used to maintain or seal the pressure of fluid during unit operation. The pumping unit moves around the rod to pull whatever you are trying to access — such as oil — to the surface. The stuffing box helps maintain the correct pressure inside the unit during use. It prevents leakage around a piston, rod and other moving parts that work inside a cylinder or other vessel.

Knowing When to Replace Your Stuffing Box Rubbers
Replacing stuffing box rubbers regularly is important for ensuring you do not have any leaks when working with your pumps. But how do you know just when to replace your stuffing box rubbers? Here are the three basic stuffing box maintenance steps you should be in the practice of taking.
1. Inspect the Stuffing Box
A stuffing box inspection should be your first step when considering whether or not you need to replace your stuffing box rubbers. Start by accessing your stuffing box and observing whether or not fluid is coming through. You may have a leaking stuffing box if it is, although not necessarily.
2. How Do You Fix a Leaking Stuffing Box?
Your first step should be to tighten the cap nut and backing nut. If this stops the fluid from coming through, you probably don’t need to replace your stuffing box rubbers yet. If the problem keeps recurring, you will want to replace your rubbers rather than continuing to tighten the nuts because you could create scoring damage.
If your stuffing box is dripping a little bit while the system is running, that means it's working correctly. You need some lubrication to prevent the shaft from overheating. However, if you are getting a more consistent fluid flow, it is time to replace your stuffing box rubbers.
3. How to Change Stuffing Box Rubbers and Address Stuffing Box Leaks
If you need to service your stuffing box, start by measuring the inside diameter of the packing nut. Before you can repack the stuffing box rubbers, you’ll need to remove the old packing with a hooked tool. Once that is done, take your packing, ensure you have the correct type of packing and the proper size, and get ready to insert it into the shaft.
Then, use a blunt tool to get the new packing into the stuffing box. Thread the nut on to push the packing into the shaft. You can use a mirror to ensure you are getting the packing in sufficiently. Once your rubber is in the shaft, tighten the nuts to finish the replacement. After completing the process, run the pump to make sure you have resolved your leaking problem. Assuming you get only the small drip, your stuffing box should be functioning optimally.
4. How Much Should a Stuffing Box Drip?
A stuffing box should be watertight when you turn it. However, there must be a drip when you move it. Two to three drops per minute is the ideal stuffing box drip rate.
