BOSCH PROF COMPRESS TESTER

The Bosch FIX 7828 is a professional engine compression tester kit designed to accurately diagnose engine condition. It helps detect worn piston rings, burnt valves, and blown head gaskets. The kit works on most foreign and domestic vehicles, small engines, motorcycles, snowmobiles, and ATVs.

This compression tester features a 2 1/2-inch gauge with standard and metric scales (0-300 psi and 0-2100 kPa). It includes adapters for most standard spark plug threads, such as 10mm, 12mm, 14mm, a 14mm long reach adapter, and 18mm. A push-button side relief valve allows for repeat testing without disconnecting, and a quick disconnect coupler enables faster connections.
