Rings seal the space above the piston and wipe the oil off the cylinder wall. When an engine burns oil and compression drops, the rings are the first thing to look at.
Rings are our strongest position. Best Parts is the authorised distributor for NPR of Europe in Serbia, and the range covers everything from small two strokes to large truck diesels.
Rings for the full IMT range, UTB Universal 450, Zetor, KHD and LDA 450.

Piston, liner and rings as a set
In an overhaul, rings are rarely replaced on their own. If a piston or a liner goes in too, we supply the whole set from one source, so the sizes match each other.
We keep rings in STD and in first and second repair sizes. In the NPR catalogue the sizes are marked STD, I SPC and II SPC, according to the cylinder diameter.
The engine type or a catalogue number off the old set is enough for us to check. If there is no number, send the cylinder diameter and the number of rings per piston.
Anything not in stock we order directly from the manufacturer. We deliver across Serbia, and for larger batches across Europe.
