So, they are of circular cross-section and unlike classic rubber washers, the cavity inside the circle is much larger. They are very flexible and pliable. They are produced in different diameters and different hardness, depending on the purpose.

The main purpose of rubber pressure washer is gasket hoses, pipes and similar products. They are extremely flexible and enable both rotational and linear movement. It ensures with certainty that no fluid will leak under any circumstances. This rubber pressure washer is ideal for pumps, hoses and rods that work under pressure. 

Every part on these appliances will fit perfectly with this rubber washer. Pressure washers simply cannot function without these washers. They ensure that water can neither enter nor leave the appliance. They stick all the parts so tightly together that the machine simply becomes compact. If there is a water leak in some parts, the maximum water pressure is immediately lost. The work will not be done well, and the costs of wasting water and time will increase. In addition to water, they are ideal for machines that work under pressure transporting crude oil, gasoline, propane and various oils. These erasers are used in engines, gearboxes, and are simply available everywhere: from the shower cabin to the aircraft pump.
