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.
Overtightening a spark plug will stretch the plug body and potentially result in breakage upon removal. For gasket-type plugs, install the plug until finger-tight. Then if the plug is being installed with a new gasket, use a spark plug wrench to apply a 3/8 to 5/8 turn â depending on head material. (See chart below.) When reinstalling a used spark plug with a used gasket, only Â¼ turn is necessary, regardless of head material.
