FIP:
Female Iron Pipe Connection
There are two types:
1) A female straight thread fitting or slip joint connection
may be attached to a tapered male thread, as long as a
gasket or seal is included into the female fitting design. A
thread sealant alone will not seal. In this case, a thread
sealant may actually interfere with proper installation,
causing the joint to leak.
2) Female tapered threads. Although you may use a
sealant for female tapered thread, the fitting may not seal
if it is attached to a male straight thread like a faucet or
toilet connection.

Tapered Pipe:
Tapered pipe threads do not need a gasket or cone seal,
but a thread sealant must be applied to the male
threads only, before the joint is assembled. Use care to
avoid getting sealant inside of the pipe. Tapered thread
joints seal better as they are tightened. This makes them
ideal for leak free iron pipe joints.
