A. No, because barb fittings are designed to be pushed into the tubing or hose, and then a hose clamp is installed to complete the connection. There may be times when a lubricant, such as water, might be needed to help insert the fitting. This of course will depend on what is being run through the hose and fittings, as you wouldn't want to use a lubricant that is not compatible with what is flowing through it.
