Size:20.5mm*2mm
The inner diameter of the mp9 brass cylinder is 20mm, and the O-ring with an outer diameter of 20mm is used. It can be used at present, but after a period of friction, the air tightness will be poor.
The outer diameter of this product is slightly larger than the diameter of the inner wall of the cylinder, which can achieve an effective seal. In addition, the characteristics of the fluorine rubber O-ring itself - "oil resistance and wear resistance", will greatly extend the use state and service life of the internal rubber parts.
The size of this O-ring is non-standard. At present, there are very few manufacturers of sealing rings on the market, and the price is relatively high. In order to meet the needs of our own modification plan and reduce the cost, we simply opened a set of molds and put them on the shelves at the same time. A separate O-ring link to benefit players at a relatively low price.
In addition, the airtight solution of the mp9 ladder racket head is not only to replace the O ring, but also to add fine grinding of the racket head. A single O ring cannot solve the problem, please know.
