Polyball of a water tap ball tap manufactured about 20 years ago was destroyed and it began to overflow, so it was used for pol ball substitution. It is a water heater with hot water reaching 65 ℃, but it was not equipped with ball tap of heat-resistant polyballs, I checked that the screw of the pol ball be M6, but I did not find it. Although it is best to replace with a heat resistant ball tap, only pol balls are exchanged considering aged deterioration of each part. Would you remodel the arm or remodel the polka ball? Finally, I decided to retrofit the screw holes of the poly balls to 5.1 mm and make it to M6 screw processing. I made a hole with a drill and made screw machining of M6, but I managed to fix the arm somehow. Would you like to establish a M6 specification of a heat resistant polyball? I would like you to sell an unusual thread size such as using screws on both ends for M6 on both ends and W3 / 16 on the other.
Although it is currently progressive type, the one we have been acquiring from the beginning, water has been submerged in the poly sphere though it has not uncovered a hole unexpectedly, if you are searching with monotaro you know the heat resistant poly sphere ordered It will be carried, probably, I think that I can go with it, there are stainless steel and copper balls, but it is saved because it is cheap
