4.000-4.090 Adj Ring Comp

Our Adjustable Tapered Ring Compressors work just like our solid models, except that they incorporate a split down the side and a large hose clamp for adjustment. Perfect for those who will be working on a variety of bore sizes or for those sizes not covered by our standard ring compressors. Each model has a range of about .090", so one of these can replace several of our regular style. Hard anodized for wear, and color coded for ease of identification.
