Graphtex Ultra GTU Shaft Packing Customer Questions and Answers
Question
Will this work on a 1 1/4" powerboat shaft with a standard flexible stuffing box? I'm not sure of the packing size until I pull it out.

After you figure out the size packing that you need you will find this product easy to cut to size and install. Once installed easy setting up the packing compression. Initial run-in produces a little bit of minor heat.

I just put them in a 35 foot Egg Harbor and drove across Lake Ontario and had no issues or problems with them at all. Just make sure you put them in correctly .

1 1/4 was my shaft size and one kit did both shafts. No more leaks

It will work fine. There are other good options. Teflon inpregnated or the old wax version which requires a drip per minute. The newer ones require less but still require some. Stainless steel does rust... In the absence of oxygen it will eat through the shaft.

Is 1/4" the actual width or is it a little larger to allow for compression? I need to fill a 0.265" gap between shaft and stuffing box.
Asked on 02/25/2018 by Don from huntington NYTop Answer
Hi Don, 1/4" is the width/height of the packing material. The extra .015" will help slide the packing in, as it is a woven material and doesn't necessarily hold a perfect 1/4" square. Once the stuffing box is tightened, it will squeeze it to fit that extra .015" as well. The next size is up is 5/16" (.31") which will not squeeze easily into that gap properly. If the stuffing box is original, or you can reference the stuffing box manufacturer, they may also indicate which packing material is designated for that specific one.

How do I find out packing size I have a one inch shaft 1 and 3/4 packing box?
Asked on 07/28/2016 by LEIA GLASGOWTop Answer
Subtract the shaft size fromt the size of the stuffing box and split the difference. this would be the size of the space on either side of the shaft. So you'd have 6/8ths left over, divided in half you'd have 3/8ths space on either side of the shaft
