I used it as a damper through a burned bolt inside. At the time of falling, the bolt collapsed but there was no damage to the rubber. Rubber is firm. I do not know the original purpose of use, but it is appreciated to be able to easily select and purchase these special products.
Although genuine products are 700 yen (tax excluded), we exchanged a total of 487 yen × 8 places for this product (299 yen) and hose clamps purchased at home centers of 188 yen. I searched for cushion rubber at a nearby home center, but it was not there. Monotaro was the cheapest.
