Nipple 1/8F x 1/4M SB2 in brass

The name says a lot about the size and the design. The designation 1/8F indicates a side with internal thread (F usually stands for female) and 1/4V a side with external thread (V usually stands for female or male, depending on the manufacturer's naming). Because the two sides have different sizes, a fitting like this lets you make a transition from a smaller to a larger connection.

What is this nipple intended for?

Brass nipples are used to connect components in an installation or to change from one thread size to another. They are found in sanitary connections and heating installations. For the precise area of application, the maximum pressure and the permitted temperature, consult the manufacturer's technical data, as these are not included in this product description.

How to choose the right 1/8F x 1/4M SB2 nipple

First check the thread size of both connection points, because 1/8 and 1/4 refer to the nominal thread size in inches and not to the actual outside diameter. Then determine which side needs an internal thread and which side an external thread, so that the fitting connects to your existing parts. If you are unsure about the combination, compare the markings on your current parts or contact Proffix before you order.

Material and sealing

Brass is a commonly used material for fittings in water and heating installations. To seal threaded connections properly, you usually use a sealant such as hemp or PTFE tape. Tighten the connection firmly, but not too hard, so the thread is not damaged.
