New, never-used MADDOX Deluxe Compression Test Kit, model MH20B-1, Harbor Freight item number 64917. The case was opened for inspection and photographs, but the kit has never been used. It appears complete and includes the compression gauge, hoses, rigid and flexible extensions, threaded adapters, small accessories, original carrying case, and owner’s manual.
This product would be ideal for automotive repair shops and professional mechanics requiring a high-quality, professional compression test tool for reliable engine performance diagnostics and repairs.
