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.
Good quality compression joints are superior to pushfit fittings which are problematic. When using compression use the pipe insert and wrap the olive with PTFE tape. It is by far the best approach if using plastic pipe. Compression are no more expensive that pushfit and easily demountable.athstyle Active Member. Using compression fittings on plastic pipe is fine in theory but in practise it would be a nightmare. The pipe would be spinning all over the place when the fittings are getting tightened.
