Sunbeam Coffeemaster Collectors Corner (The Vac-Pack)

Photos of a C30C with the original gasket/seal on the left, the Dayseal replacement gasket on the right. The Replacement gasket does set the top vessel higher, resulting in a larger clearance between the tube and the bottom of the lower vessel. This can result in overflow during brewing.

The left unit stayed on High longer so the right unit won the race.

W'nC - Where did you get your Dayseal aftermarket seal from? Is there more than one piece?

The gasket and the O ring (secondary gasket) both from Dayseal.

Look at the one on the left, it's mint. Even the white paint on the switch is like new.

I have a C30A that I recently purchased on eBay. The original gasket was in fair shape but did not seal sufficiently to hold vacuum in the lower pot. Only about 2/3 of the brewed coffee would return. I ordered a new C30 gasket and O-ring from Dayseal.com.

My set arrived with obvious manual modifications to allow the seal to maintain the original depth. Once installed, it worked perfectly on my test 6 cup run. The C30A can brew 8 cups but that test will have to wait until my pulse rate returns to normal (my caffeine level drops) :shock:

Prior to installing the new seal system, I measured the top-pot height with a combination square. The original height was 9.75" for my C30A. Once the Dayseal system was installed as per the diagram on Dayseal.com, I rechecked the height and confirmed it to be the same with out any modifications on my part.

Here are some pictures comparing the original 63 year old neoprene gasket from my C30A with the embeded retainer ring (on the right) to the new Dayseal main seal. The as-received manual modification to the Dayseal are apparent in the photographs. Subsequent post will show the assembled height comparison and another picture of the inverted C30 Dayseal main gasket. I didn't include a picture of the O-ring - it looks just as you'd assume

More pictures of the original C30A vs. C30 Dayseal.

The 6 cup test brew did not produce any overflow like W'nC experienced. This was most likely due to the as-received modifications made to the C30 Dayseal that maintained the original top-pot assembly height with respect to my C30A.

I'll be ordering another gasket for my other C30C as well as one for the C20.

Dave, I was just thinking (amazing), Even if the assembled height of the top vessel is the same the bottom of the tube can still sit differently when placed into the lower vessel due to the different gasket.

I've been thinking* about that too (*-see what caffeine, cafestrol and kaweol does to you :shock:

). That will be the next set of measurements I'll take. I'll need to juggle two squares to determine that measurement. The side-by-side pic shows a slightly different bevel profile but i doubt it's that much different. The new one is so soft it will likely conform to the shape of the bottom-pot. The original Sunbeam is so stiff and backed by the SS spring instert would make that less conforming to the shape of the bottom-pot. I can reuse the original Sunbeam gasket as I didn't destroy it to extract the retainer ring. The 'acid test' will be tomorrow when I run a full 8 cup brew cycle with the Dayseal system.

I used my 1/4 sheet sander and 150 grit to thin out the new gasket a little, to make it more like the original one. Even though I kept comparing it to the original, I guess I went a little too far, the new gasket ended up being loose after I installed it. I moved the O ring between the tube and the upper vessel, everything is tight, test run with water is OK, coffee in the morning. At this point I figure the retainer is sealing the gasket against the bottom of the upper vessel.

No problem brewing a full pot with the Dayseal system installed as received. Normal time and no overflow issues.

I measured the overall C30A height with both gasket systems installed and assembles. They both had the same 11 11/32" overall height.

Good to hear.

I have some measuring sticks similar to those.
