The I.D. was correct but the shape was not as cupped as the original . As I watched some videos I saw the rings can be pushed into the cylinder. I assembled the compressor and it's been working fine. The CAC-248-2 is a better fit for my 6 hp. Craftsman compressor but these work. ## Features - Compatible with replacement piston ring model parts: KK-4835, KK-5081, A02743, K-0058 ,K-0650 - The oil-Less or oil-Free piston ring fits for many air compressors including DeVilbiss, Porter Cable, Sears, DeWalt, Snap On, Ex-Cell, Air America, Charge Air Pro, Dayton, Makita, Grainger and many other private label air compressor brands - Package including 2 pieces DAC-308/CAC-248-2 piston ring, compatible with Craftsman air compressor - Approximate size outside diameter (OD): 2-9/16" , inside diameter (ID): 1-7/8", thickness 0.1" - High Quality Rubber Material,Good Reliability,Durable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08521Y3BM | | Best Sellers Rank | #356,224 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #421 in Air Compressor Replacement Parts | | Brand | MEFONKOU | | Brand Name | MEFONKOU | | Color | Black | | Customer Reviews | 4.2 out of 5 stars 125 Reviews | | Item Diameter | 2.56 inches | | Item Weight | 9.07 g | | Manufacturer | Onlineseal | | Material | Rubber | | Material Type | Rubber | | Model | DAC-308 | | Nominal Inside Diameter | 1.88 inches | | Nominal Outside Diameter | 2.63 inches | | Number of Items | 2 | | Part Number | DEBatch3-5016 | | UPC | 745245577374 | | Unit Count | 1 Count | ## Product Details - **Material:** Rubber - **Nominal Inside Diameter:** 1.88 Inches - **Item Diameter:** 2.56 Inches - **Brand:** MEFONKOU - **Nominal Outside Diameter:** 2.63 Inches ## Images ![DAC-308 Piston Ring for Craftsman Air Compressor CAC-248-2 KK-4835 KK-5081 K-0650 K-0058 A02743 (2/Pack) - Image 1](https://m.media-amazon.com/images/I/41LRW2LNz4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by W***N on April 23, 2026* Compressor is like new ### ⭐⭐⭐⭐⭐ They work for a substitute for CAC-248-2 *by G***C on June 14, 2020* This was not an exact fit for my compressor.
