Piston Ring Excellence. Since 1956.

…what does that actually mean?

It means, very simply, that we have been accepted to supply our large bore piston rings directly to some of the world’s leading builders of diesel and gas engines.

This isn’t something that happens overnight. When OEMs come knocking at our door then it is normally the start of a process which will take lots of behind the scenes work – as with a recent 3-day virtual audit from a household name OEM customer which we passed with flying colours a full 16 percentage points above the bar set for acceptance onto their vendor programme.

Over the course of further months, and sometimes years, sample piston rings from QIN are rigorously tested. Sometimes this will be in the form of accelerated fatigue testing in a lab against a series of defined protocols. Sometimes our piston rings will be run on a test engine at the OEM’s facility for 1000s of hours and the level of wear closely analysed along the way. Sometimes they will be reliability-tested for further months and years out in the field, on vessels as they navigate the planet’s oceans or locomotives as they cross continents. Sometimes it can be all of the above. And that’s all just fine with us – we’ve been in this game since 1956, and are here for the long-haul.

What does that all add up to for those who choose to fit QIN piston rings to their engines? Peace of mind.

Marine engine piston rings, locomotive piston rings, industrial piston rings, power plant engine piston rings: we cover all these applications here at QIN across a bore range which extends from 160mm up to 600mm.
