Rock Tumbler Belt 5-Pack for KomeStone K1, K1 Pro, K3 – Includes 2 Upgraded PU Belts + 3 Rubber Belts – Durable Replacement Kit, Not for K2 or K4

Compatible with K1& K1 Pro Rock Tumblers: Official replacement belt kit designed by KomeStone, perfectly sized for our K1 and K1 Pro rock tumblers. Not compatible with K2 or K4 models. Upgraded Combo: 2 PU Belts + 3 Rubber Belts: We’ve improved the standard 5-pack rubber belt set by adding 2 high-performance PU belts. PU (polyurethane) belts are stronger, more heat- and wear-resistant, and last significantly longer than traditional rubber belts. Buying Tip: PU Belts Recommended for Frequent Breakage: If your rubber belts have broken during use, we recommend switching to our 2 PU belts (sold separately) for improved durability and reduced maintenance. PU belts are ideal for long tumbling sessions and heavy use. Buying Tip: Choose Combo If Rubber Belts Still Work Well: If your tumbler’s rubber belts are still in good condition, this 5-pack gives you flexibility—continue using rubber belts while upgrading to PU when needed. Perfect for users who want both immediate use and future-ready backups. Important Note: Use Only Genuine KomeStone Belts: Avoid using belts from other brands, as poor fit or quality can damage your machine or reduce its lifespan. Always use KomeStone-certified parts for best performance and peace of mind.
