Repair kit of magazine sealing rings suitable for the models MP-654K, MP-661K Drozd, Blackbird, this set drawn up is handmade by to order. Improved sealing elements included in this extended repair kit were made by special order from higher quality and more expensive materials, so they have an increased resource, provide better sealing and are much less likely to need to be replaced.
The proposed advanced repair kit is great for all modification models MP-654K, MP-661K Drozd/Blackbird, 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 as 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 full 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 80 pieces of sealing elements of which 20 pieces of each type):
1. Valve sealing rings made of durable polyurethane (in the photo they are located at the very top, are with tint transparent and they have the smaller diameter of all presented, fit snugly to the 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 material was selected that has a high resistance to 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 the black lamp rings and look like washers, they also have a tint transparent),
4. The sealing rings of the valve seat are black (in the photo shown they are located in the lower part and have the largest diameter with the thinnest walls. Made of a more durable material and have an optimal level of elasticity).
The package delivery includes repair set of 80 high-quality sealing elements.
