Description
Overview:
The C12 Ring Set +030 (OEM C12RS030) is a genuine Villiers replacement ring set for classic Villiers single‐cylinder petrol engines, including the C12 and MK12. It restores cylinder sealing by renewing the piston compression and oil‐control rings, helping the engine start reliably, hold compression, and manage oil consumption. The +0.030 in oversize (0.76 mm) is intended for engines that have been rebored and use matching +0.030 in pistons. Manufactured from durable, wear‐resistant materials suitable for high temperatures and continuous service, the rings are sized for a precise fit in standard pistons of the correct oversize. As unused vintage old stock, the parts may show light tarnishing or storage marks, but this does not affect performance. Ideal for maintenance and faithful restorations of period machinery using Villiers power units.
