Autoclave Fittings and Their Uses

Autoclaves are used in situations that require high temperatures and pressure. Normally, autoclaves are used for sterilization purposes. Other uses of the equipment include scientific experiments, laboratory diagnosis, industrial processes, and much more. In order to withstand the extreme temperature and pressure, it is important to use special autoclave fittings which include the following: 1. Coupling Coupling is one of the most important autoclave fittings. This device makes it possible to connect different accessories that make up an autoclave. The coupling will connect the steam pipes leading to the autoclave. The coupling is also used to safely connect gas or electricity connections. There are several types of couplings used.

These are as follows: •Elbow: This is a right angled connection used around the corners or to curve a connection. •Straight coupling: This is similar to a straight pipe and is used to connect two pieces in a straight  line. •Tee: This is a “T” shaped connection used to connect three points. •Cross: This is also known as the “junction”. It is a four sided connector that can connect four points. It is also used to split a single joint to form four different connection points. 2. Valves A valve is basically a device that controls the amount of steam, temperature, or pressure inside the autoclave. This autoclave fitting normally works together with a regulator or thermostat. When the temperature exceeds the required levels, the valve automatically opens up to release excess pressure. When more pressure is required, the valve closes to contain the extreme temperature and pressure. Valves come in different sizes, shapes, and designs to suit different application. These include Low pressure, medium pressure, and also high pressure valves. The valves also come in sizes that range from 1”, 9/16”, 3/8”, 1/2”, 5/16”, and ¼ inch. Types of valves include the ball or needle valve. 3. Plugs Plugs are used to seal off the end of an attachment or another autoclave fitting. The plug may either be a permanent seal or may be semi permanent. The type of plug will also depend on the amount of pressure being released. A high pressure environment requires a sturdier plug as opposed to a region of low pressure. The plug and the collar are used interchangeably, hence in case a plug is used, the collar is not needed. These autoclave fittings may come threaded or unthreaded. Threaded plugs form pressure tight seals. Unthreaded plugs are used in areas that have minimal pressure. 4. Gland The gland is also another common autoclave fitting. This device serves the same purpose as a plug or collar. However, the gland is more permanent and forms a better connection or seal. The gland usually comes in threaded form hence once screwed in place, it remains intact unless unscrewed. Autoclaves may be powered by electricity, steam, or gas. At full pressure, the forces inside the equipment are extremely high. In case the pressure or temperature escapes, it can lead to disasters. It is necessary to make sure the autoclave fittings are of the highest standards, and meet the recommended safety specifications.
