Bronze Thrust Washer

1 in stock

Bronze Thrust Washer, can be used. The long gun supports the circumference of the cap to protect the bottom key. They are designed to prevent movement along the line of the eye. Rifles need to be chiseled to add extra oil. For high pressure applications, the grooves can be filled with graphite to provide a rigid material for the gas system.


When the traditional gasket is in use, the corrosive liquid at the sealing port will cause corrosion to the gasket, thereby affecting the sealing performance, and the gasket body is directly in contact with the sealing port, which is more likely to cause corrosion to the gasket and affect the performance of the gasket. The problem of service life, the VIIPLUS bronze thrust washer body is provided with positioning holes, and the gasket body is also provided with a plurality of installation through holes. Corrosion resistance improves service life.

Product features
