Pipe size is more than a number
A pipe may be described by a nominal size, an outside diameter, an inside diameter or a product-specific series. These measurements are related, but they are not always interchangeable. Two products described with similar numbers may still use different fitting systems.
If the old pipe marking is unclear, take a well-lit photo showing the full text and another of the pipe end or fitting. A ruler in the photo provides context, but the printed specification is usually the better starting point.
- The full marking printed on the pipe
- The material, such as PVC, UPVC, CPVC or HDPE
- The stated diameter and pressure class or series
- The product standard or brand specified for the job
- The connection type required by the fitting
How to check common PVC pipe size searches
Buyers often search for 32 mm, 50 mm, 63 mm, 75 mm or 160 mm PVC pipe. The number helps identify a general requirement, but it may not identify the exact product. Send the size exactly as written on the pipe, drawing or bill of materials, along with the application, pressure class or standard, required length and quantity.
Be careful with searches such as 63 mm PVC pipe in inches or 75 mm PVC pipe in inches. A simple conversion can mislead because nominal size and measured diameter may differ. Use the manufacturer's chart for the specific product system and confirm that the fitting follows the same sizing system.
Match the reducer to both sides
A PVC reducer connects compatible pipe or fitting sizes. Specify both ends, the material, the product series and the connection method. Also state whether the item is a reducer bush, reducing socket or another design.
A PVC reducer and a CPVC reducer can look similar while belonging to different systems. Confirm compatibility instead of choosing by appearance.
Other fittings to include in your enquiry
Depending on the specified system, a pipe order may also need items such as a plug or end cap, elbow, bend, tee, coupling, socket, UPVC ball valve, non-return valve, flange adaptor, tail piece or compatible casing and CPVC accessories. Share each fitting's name, size, material and connection type. A clear photo or drawing helps identify less familiar parts. Current availability is confirmed for each enquiry.
What to check when buying casing pipe
Casing pipe is used in different settings, so state the intended application and follow the installer's or engineer's requirement. Ask about the specified material, diameter, length, wall or product series, and any required slots or accessories.
Do not substitute a different pipe based only on a similar size or broad product name.

Frequently asked questions
How do I identify the size of a PVC pipe?
Read the printed marking and note the material, size, series or pressure class. If it is worn, take clear photos of the pipe and its end, then confirm the specification with the supplier or manufacturer.
Is 63 mm PVC pipe the same as 2 inches?
Not necessarily. Nominal pipe size and actual diameter can differ, and product systems vary. Check the specific manufacturer's sizing chart and match the fitting to that system.
What information do I need to buy a PVC reducer?
Provide the material, both connection sizes, reducer type, connection method and any brand or standard requirement. Confirm compatibility with the pipe series before purchase.
Can I use a PVC fitting with a UPVC pipe?
Do not assume that similarly named products are compatible. Match the fitting to the pipe material, dimensions, joining method and manufacturer's system.
What is the difference between a pipe size and a fitting size?
A pipe may use a nominal size, while its fitting is designed for a particular product system and actual dimensions. Use the pipe marking and manufacturer compatibility information.
How should I ask for a casing pipe?
