Tested 4 cylinders and used screw in adapters, did compression on all 4 cylinders showed 75lb per cylinder then used a rubber adapter and tried each cylinder and got a reading of hundred pounds per cylinder. You should have no difference between screw adapters and rubber adapters. Very confused right? I would go with another child that doesn't seem to work or doesn't work at all. I would not recommend this product
