After whale-watching in Monterey Bay and a bayside meal at Bubba Gump Shrimp Co. on Monterey's Cannery Row, we headed south on Highway 1. We twice diverted within the few miles between Monterey and Carmel to the 17-Mile Drive, which winds past Pebble Beach.
Compression fittings work by the compression of an âoliveâ between two tapered surfaces and the pipe itself. The two surfaces are the body of the fitting (be it a valve, connector or any other type) and the nut. Using a spanner and a pair of grips the nut is tightened. This exerts pressure on the olive and bites it onto the pipe. Compression fittings work well if the pipe is clean and cut properly.
Today we are going to cover the different types of fittings for compression testing on both automotive and diesel engines. Compression testing is one of the easiest way to check an engine to try and locate an internal problem by testing each cylinder against each other and what your service manual recommends as an acceptable reading for that engine.
