Compression Brass Fittings

Compression fittings, also known as brass compression fittings, are a popular type of fitting where two pieces of tubing are connected and squeezed together to form a seal. They are primarily used in the plumbing industry, but they can be used in nearly any industry or work environment where two sections of plastic tubing have to be clamped together.

Brass compression fittings are quite flexible in the connections they can allow, and this means that they are pretty easily used in a range of areas, apart from plumbing, where plastic tubing has been traditionally used. A typical use of brass compression fittings is to make a connection to a water hose or other flexible tubes. Brass compression fittings are a well-known product today, especially because they are easy to use. They only require a standard pair of pliers or similar tools to be used along with a set of compression fittings. Placing two compression fittings into position, and then tightening them should form a tight connection between the two sections of tubing. The following are some applications specific considerations for Brass compression fittings for plastic tubing;

High-pressure application

For plastic tubing, compression fittings are the ideal choice for high-pressure applications, because large compression fittings can be used at pressures exceeding 10,000 PSIG when used in conjunction with a high-pressure tubing material such as plastic. Because of smaller dimensions, pressure ratings decrease in the miniature realm, but Installation Parts Supply brass compression fittings for plastic tubing, for example, is still rated between 3,000 and 5,000 PSIG depending on the model.

High purity application

Many applications in industries like medical, semiconductor, and instrumentation require that all components be as inert and clean as possible, and compression fittings greatly simplify these applications. Engineers can avoid harmful contaminants by using brass tubing or inert plastic (PTFE, for example), and compression nuts and ferrules are often all-metal, which makes them easier to autoclave, clean, or sterilize than fittings containing plastics or internal elastomers.

Compression fittings are used in several industries and can be used in almost any fluid power system. Among their many benefits are their ability to be attached to metallic and hard plastic tubing, their high pressure and temperature ratings, corrosion resistance, and ease of connection. Although compression fittings also face many challenges, there are some tips of the trade that can help ensure a successful design.
