    PVC Imperial and PVC Metric: The Key Differences 

    Loading

    For an effective and smooth working plumbing and piping system, PVC fittings play a huge role. The right use of these fittings can make or mar the entire plumbing and piping system. This is why it is crucial to know about different PVC fittings and find the right solution. However, not many people know that PVC fittings are available in two different measurement systems. You can either go for PVC imperial or PVC metric to fulfil your needs. They have different roles and provide a safe plumbing system even if you are planning to shop for gardening. These PVC fittings will ensure everything runs smoothly. 

    What are PVC imperial fittings? 

    PVC imperial fittings are known to be manufactured in inches. They are mainly used in North America, the UK, and various other countries. All these countries use the imperial system of measurements, which is based on feet, inches, etc. 

    Also, these fittings are manufactured in standard sizes and range from ½ inch to 10 inches in diameter. The outside diameter of these fittings matches the nominal pipe sizing. Plus, PVC fittings are slightly thick and have a high-pressure rating compared to metric fittings. 

    PVC imperial fittings are also famous for being durable and chemical resistant. They are used in various applications like water supply, chemical processing, and much more. 

    What are PVC metric fittings? 

    PVC metric fittings are available in millimetres and are mainly used in Asia, Europe, and various other countries. This metric system is known to be based on metres, centimetres, as well as millimetres. It has been used by people for more than 200 years. 

    The PVC metric fittings are available in standard sizes, like 16mm to 250 mm in diameter. However, the outside diameter of these fittings can match the nominal pipe size. Also, they have a low pressure rating along with thin walls. Thus, they are light and simple to carry. 

    The best thing about these fittings is that they are durable and chemical resistant. 

    The key differences between PVC imperial and metric fittings 

    Here are some key differences between PVC imperial and metric fittings: 

    • Measurement system 

    The major difference between the fittings is the measurement system. This system is used to manufacture them. However, PVC imperial fittings are known to be manufactured in inches, whereas PVC metric fittings are known to be manufactured in millimetres. 

    • Size 

    The size of both the fittings also varies. PVC imperial fittings range from ½ inches to 10 inches in diameter. However, the PVC metric fittings range from around 16 mm to 250 mm in diameter. In simple words, PVC metric fittings are small as compared to PVC imperial fittings. 

    • Compatibility

    PVC imperial fittings are not compatible with PVC metric pipes. Also, PVC metric pipes are not compatible with PVC imperial fittings. In other words, PVC imperial fittings can be used with PVC imperial pipes, and PVC metric fittings can be used with PVC metric pipes. 

    How to choose the best PVC fittings? 

    Making the right choice between imperial or metric PVC fittings depends mainly only on the piping system. If you have PVC imperial pipes, then it is essential to opt for PVC imperial fittings. Also, if you have PVC metric pipes, then it is essential to go for PVC metric fittings. 

    While choosing the best PVC fittings, try to take the fittings size into consideration. PVC fittings are known to be manufactured in standard sizes, and selecting them in the right size is highly essential. Also, ponder upon the application type for which the fittings will be used. Select the fittings that are essential for a certain application. 

    Can imperial PVC fittings be matched with metric pipe or vice versa?

    It is impossible to match the PVC imperial fittings with the metric pipe as they have different measurement systems and dimensional specifications. Even if you want to, an adapter is required, which is available at plumbing supply stores. However, the compatibility as well as suitability of the adapter are essential, and it depends on the certain application or condition. Otherwise, you can always contact the best plumber to have a safe connection. 

    Conclusion 

    Choosing the PVC fitting can make a huge difference in the upcoming years. The above-mentioned difference between PVC imperial fittings and PVC metric fittings will allow you to understand which is the right one for you. They have different measurement systems, sizes, and compatibility. If you plan to shop for gardening, then Bayton Horticulture Centre is the right place for you.
