What is this?
A bonded seal is a type of washer used to provide a seal around a screw or bolt. Consists of an outer annular ring of carbon steel and an inner annular ring of nitrile butadiene rubber that acts as a gasket.
Are there any advantages of the product?
The nitrile rubber is bonded by heat and pressure to the outer ring, which holds it in place. This structure increases resistance to bursting, increasing the pressure rating of the seal.
Because the bonded washer itself acts to retain the gasket material, there is no need for the parts to be sealed to be shaped to retain the gasket. This results in simplified machining and greater ease of use as compared to some other seals, such as O-rings.
How to use it?
The self-centering bonded washers are high-pressure seals that are used in the Mechanical, Hydraulic, and Pneumatic pipelines.

Used these to seal banjo bolts for a injection pump on a old diesel tractor. Worked very well and sealed the air leaks

Used this gasket on a M14x1.5 outlet fitting on an oil transfer pump. The gaskets sealed perfectly. The pump only produces 30psi, but this seal worked well in this application. I have no doubt that it would work well at higher pressures also.

These were exactly the same bonded washers used in my central hydraulic tire skates.
