What is the purpose of piston rings?

Piston rings have two main jobs: they seal the combustion chamber to maintain compression and prevent gases from leaking past the piston, and they scrape excess oil off the cylinder walls to prevent it from entering the combustion chamber.

What does 'plain ring set' mean?

A 'plain ring set' typically refers to a standard replacement set that matches the original equipment manufacturer's design and specifications without any special coatings or advanced features.

Are these rings compatible with all Mack MP8 and Volvo MD13 engines?

This ring set is designed as a direct replacement for OE part numbers 20 747 511 and 21 253 763. It's always best to verify these OE numbers against your specific engine's requirements before purchase.
