High quality 95 alumina ceramic water tap disc

Ceramic Coffee Grinding Disc as Coffee Pepper grinder Mill Parts

Product Description

15.8mm size alumina ceramic disc for water tap

15.8 alumina ceramic disc is the conventional size for faucet spool, hardness 1000.

The product is made of 95 alumina, with high hardness, high mechanical strength, high pressure resistance, good sealing and low cost.

There is no bubble in the blank, which is the key supporting material of energy-saving ceramic spool faucet.
