Description
Overview:
The Piston Ring Set 020 for Lister TS/ST range engines is a genuine Lister Petter spare, supplied to restore correct sealing and compression in vintage and working engines. Manufactured from durable, heat-resistant ring steel/cast-iron materials, the rings are precision finished to seat quickly and maintain a stable oil film. The /020 specification denotes a +0.020 inch (0.51 mm) oversize to suit cylinders that have been re-bored accordingly. This matched set is designed for Lister TS and ST engines, helping to reduce blow-by, control oil consumption, and deliver consistent starting and running performance. As unused old stock, items may show light tarnish or storage marks, without affecting function. A practical choice for routine maintenance, overhaul, or faithful restoration where a genuine, correctly sized ring set is required.
