About Stuffing Box Packing

Stuffing boxes are used in the oil and gas industry, as well as in the agricultural and industrial sectors. They provide a tight seal around solid wireline whether stationary or moving. Inside the stuffing box, the packing rings are tightly compressed to create a strong fluid seal around the shaft or the pumping unit as it moves. Stuffing boxes are designed to prevent gases or liquids from leaking as the line moves.

At McClain Oil Tools we offer quality stuffing box packing at an affordable price for your wireline and slickline needs. We offer a variety of packing materials, for a wide range of applications. Find out why our customers count on us for their wireline products. Contact us today for a quote.

How to know when to Replace Your Packing

Regularly replacing the packing is critical for making sure you do not have any leaks in the stuffing box. But how can you be certain when it’s time to replace your packing? The following are some basic maintenance steps you should take.

1. Inspect the Stuffing Box

When deciding whether or not to replace your packing, a good inspection should be your first step. Start by accessing your box and paying attention to whether or not any fluid is coming through. Although it’s not always the case, it’s still possible you could have a leak.

2. Determine if the Stuffing Box is Leaking

Your first step should be to tighten the cap nut and lock nut. If this stops the problem of excess fluid coming through, you probably don’t need to replace your packing rings yet. However, if the problem persists, you will want to replace the packing rather than continuing to tighten the lock nuts. Doing so 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 do still need some lubrication to ensure efficient heat transfer and prevent overheating. However, if you are getting a more consistent flow of fluid, it is time to replace the packing.

3. Address Any Leaks and Replace Packing Material

If you need to service your stuffing box, start by measuring the inside diameter of the packing nut. Before you can replace the packing, you’ll need to remove the old rings of packing with some kind of hooked tool.

Once the old packing comes out, take your replacement packing, making sure you have the correct size and type for your stuffing box, and insert it into the shaft.

Then, use a blunt tool for packing stuffing into the box. Thread the nut on to ensure tight shaft packing. You can use a mirror to make sure you are getting the packing in sufficiently and that everything is properly seated.

Once your new packing is in the shaft, tighten each packing nut to finish the replacement. After you have completed the process, test your equipment to make sure you have resolved your leaking problem.

Assuming you get only a slow drip, your stuffing box should be functioning optimally.
