Nipple 3/8 female male SB2 (3/8F x 3/8V)

The item is in the category Brass couplings, under fittings for sanitary and heating. A nipple is a small, separate link in a piping setup. You use it to extend, relocate or adapt an existing threaded connection to fit another part.

Recognising internal and external thread

With an internal thread, the thread is on the inside of the opening; with an external thread, it is on the outside. First measure or check which thread your connection has and which thread the part you want to connect to has. An internal thread only fits an external thread of the same size and the same thread type. The size code 3/8 refers to the thread size in inches, not to the outer dimension of the part itself.

What a nipple 3/8 female male is suitable for

A nipple like this is used in installations that work with threaded connections, such as piping, taps and connections in sanitary and heating systems. Always check that the material and size suit your application and the medium flowing through the pipe. The product page states the size code and the material type; other properties are not listed.

Sealing and installing

Threaded connections are generally sealed with a suitable sealant. At Proffix you can find, for example, flax or hemp per strand. Tighten the connection by hand, then tighten it further with suitable tools, without excessive force, so the thread is not damaged.
