Our Story
A quick look at where Piston Ring Service started — and where we’re going.
Our Story
In 1953, James Tennant Sr. started Piston Ring Service & Supply as a two-man Machine Shop in central Winnipeg. Throughout its history, Piston Ring has maintained an aggressive attitude to change.
Today the company continues across generations, supported by a Winnipeg-based team and a large distribution footprint.
Expansion and acquisitions have resulted in a strong store network across Manitoba, Saskatchewan, and Northwestern Ontario.
