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.
The picture below has both threads. Itâs hard to see the difference, but there is a difference. The taper of the threads is what actually distinguishes pipe from compression fittings. On bottom of the fitting in the picture is a male pipe thread; on top is a male compression thread with nut. Pipe threads connect the fitting to another solid component, like a filter housing or a rigid metal pipe.
