Called Kopak 800 number trying to find a part number for the gasket of a walk in freezer. After being shuffled around 3 or 4 times, I wound up with a lady who seemed to know what info i was needing. After explaining it was only a Kolpak cabinet, (different brand condenser, different evaporator) we discovered the only serial number I had led only to the age of the box, 1994. However, using the old gasket dimensions and what side the hinges where on (left side hinge, 36.5 X 78 inches) she told me it was a 225191075. Sounded good to me! I promptly searched partstown for that part number and was ready to order, but alas! the measurements according to partstown was 34 X 78. A little checking around the internet has both sizes appearing, depending on where your looking. Anyone know for sure the real dimensions of 225191075 ?
I can't tell you how many gaskets I have gotten over the years that were wrong. The accrual Kolpak dimensions should match this length. (click on the notes) One of the things you need to know is what dimension they are talking about. The spec can be Dart to dart, or outside to outside. Plus with that gasket, it has a foam stiffener in the hinge side back to prevent it from rolling as it slides across the munnion. A magnetic gasket that is 7/8 inch high is one of the highest I've seen. <div>
If you go to this page, It explains the measuring of gaskets.
This one gives the models that it fits. Hopefully being a 90's unit it will be in there.
thanks for the link, that cleared up the right hand, left hand hinge puzzle. I was wondering why the gasket specified a hinge side. Unfortunately none of those model numbers matched anything I had, but I think that's the correct gasket nonetheless. Very close to what I measured with a ruler. Not sure why the partstown gasket says 34 wide, no matter how it's measured that wouldn't fit.
I've found that one has to always measure accurately with door gaskets. I always use a folding wooden ruler for this as tape measure's can vary 1/8 inch. The manufacturers of the coolers make changes over the years that might only be a small amount, and then want to drop old stock and combine part numbers to simplify.
With the deep set door and the hinge design that Kolpac used that gasket on, as the door closes the hinge side has to slide on the heated munnion about a 1/4 inch after contact of the magnet before compression. That's why they had to make a pyramid base to prevent rolling over. It's quite a unique design and the only one I ever came across that was 7/8 inch high.
