B&B Cylinder Leakage Tester
The B&B Cylinder Leakage Tester gives an accurate percent of leakage readings for quick cylinder and combustion chamber evaluation. It features a large, 3-1/2" dial and comes complete with a four foot long hose, an 18" quick disconnect hose extension, and two chrome plated adapters for 14mm and 18mm spark plug threads. Our single gauge design gives you percent of leakage readings instead of PSI readings. No confusing calculations or uncertainty as with many two gauge testers.
