Stopper of a fish bowl
From Japan
On 2017-07-11 16:32:50
It was too hard, moderately soft and very good Because the flower pot was used as a goldfish bowl, the hole was not a perfect circle and it was a little irregular circle, but there was moderate elasticity and just draining the bowl somewhat eliminated the water leak and it was nice

Stop the water distribution adjustment port of the pond
From Japan
On 2017-05-22 14:40:52
Because the diameter is not straight because of waterproof painting, I was looking for something that can stop water. I tried some before No.34, but No.34 was exactly right. Hardness was reasonable, even if you put in force and pushed in, there was no problem.

Used as a stopper for the drain of the hand bowl
From Japan

Since the side of the hole to be installed is slightly irregular and leaks water, I use it by rolling the sealing tape for waterworks and using it with a lot of force, but since it is a solid rubber, it can be stopped securely without getting into the hole too much.

Used as a cover for low pressure air leakage check of sealed parts
From Japan

It is used for sealing of mechanical parts · low pressure air leakage check. Hardness is also good, reasonable so it is good. I used it as a consumable idea, so I tried buying it for durability check, but if there is no problem I will be repeating.

Temporary stop of heat exchanger
From Japan
On 2016-03-14 14:59:46
There is more than expected effect, I am satisfied. If it dares, if it has a little shrinkage (elasticity) of rubber, could it be able to cope with the change in the inner diameter of steel pipe? However, because the case in this time is a unique place, it was able to correspond with the water stop tape.

Used for masking during bead polishing
From Japan

When I purchased a rubber stopper of No. 21, the diameter of the dimensional table was only 63, but actually there was only φ 61. The part I bought at the same time was the dimensions as shown in the dimensions. I wish I had made it one larger size.
