Sealing magazine mp-661k drozd, blackbird and mp-654k O-rings with thickened walls and smooth shape for best long seal, upgraded repair kit made to order. This tuning kit will allow change the sealing elements much less frequently, since it is made of durable rubber and polyurethane.
The proposed modernized repair kit of seals is perfect suited for all versions MP-654K, MP-661K, MP-656K, MP-562K.
Sealing rings in this improved set are made of durable, expensive materials without any defects, unlike cheaper copies, which are now mainly on the market, as well in comparison with other low-quality counterparts on the new improved rings there is no unnecessary side burr (additional protruding pieces of material). The diameter of all the rings in the new improved set is the most optimal, which has a positive effect on the interaction of parts and improves their performance, thanks to this, an ideal tightness is achieved and, as a consequence, increased performance, which is maintained for a very long time. The most important resource of the new improved kit is many times higher than that of its cheaper and lower-quality copies (analogs with unsecured dimensions and pieces of unnecessary material sticking out along the edges), therefore the new improved set of sealing elements turns out to be economically much more profitable and justified. as its service life is many times longer, the advantage is that now it’s not necessary to disassemble and reassemble the valve assembly often, having to replace the seals in it each time, which in turn is it tangibly reflected in the service life of all other steel components, since they erase the coating and quickly wear out the existing fine thread, due to this unit is better disassembled extremely rarely, which will make it possible to make a new improved set. The new improved full set includes the following components (a total of 20 pieces of sealing elements of which 5 pieces of each type):
1. Valve sealing rings made of durable polyurethane (in photo they are located at the top, are with tint transparent and have the smaller diameter of all presented, fit snugly to valve walls),
2. The black sealing rings of air-bulb for installation in its upper part (in the presented photo they are located directly under the valve rings). These black rings with thick walls were made on a new technological mold for their manufacture, a special rubber was selected that has a high resistance to strong cooling and at the same time it is not deformed, at the same time maintaining an optimal elasticity important for these sealing rings for a long time without losing its strength characteristics,
3. Sealing flat rings of the air-bulb for installation in its lower part, also made of durable polyurethane (in the presented photo they are located directly under black air-bulb rings and look like washers, also have a tint transparent),
4. The sealing rings of the valve seat are black (in the photo shown they are located in lower part). Made of a more durable rubber and have an optimal level of elasticity, possess large diameter with the thickened walls.
The package delivery includes advanced set sealing parts magazine, consists of 20 pieces of O-rings for best seal.
