Measure the outside diameter (OD) of your existing pipe with calipers or a tape measure. The size listed in the variant menu (e.g., 25 mm, 50 mm) refers to the pipe OD the fitting is designed to accept. Do not use the pipe's nominal bore or internal diameter — metric PVC pipe is sized by OD. If you are unsure, contact us with your measurement and we can confirm the correct variant.

Rigid uPVC is widely used in cold potable water systems globally. However, certification requirements vary by country and local building code. If your project requires a specific potable-water certification (e.g., WRAS, NSF 61, or a national equivalent), please contact us to confirm compliance before ordering.

Use a standard uPVC solvent cement rated for pressure pipe (e.g., Tangit PVC-U or equivalent). Clean and dry both surfaces, apply a thin even coat of cement to the pipe end and fitting socket, push together with a slight twist, and hold for 30 seconds. Allow the joint to cure for at least 24 hours before pressurising. Do not use ABS or CPVC cement — these are not compatible with uPVC.

No — these fittings are sized for metric OD PVC pipe (DIN 8062 / ISO 1452). Imperial Schedule 40 and Schedule 80 pipe use different outside diameters and will not form a reliable solvent-weld joint with metric fittings. If you need to transition between metric and imperial pipe, use a dedicated metric-to-imperial adapter or a union connector.

The full-bore ball valve (Kugelhahn) has a ball port diameter equal to the pipe bore, resulting in minimal flow restriction — preferred for applications where flow rate is critical, such as pump suction lines or high-volume irrigation. The economy ball valve (Einfacher Kugelhahn) has a reduced-port ball, which is adequate for isolation duties where some flow restriction is acceptable and cost is a priority.

uPVC fittings can be used for low-pressure compressed air (typically up to 6–8 bar at ambient temperature, depending on size and wall thickness). They are not recommended for gas distribution (natural gas, LPG) or high-pressure pneumatic systems. Always verify the pressure rating for your specific size variant and consult local regulations before using PVC in any pressurised gas application.

Bulkhead fittings are sized by internal diameter (ID) — for example, the 25 mm ID variant accepts 25 mm ID hose or pipe. They are designed to pass through a drilled hole in a tank wall or sump panel: one side has a threaded collar and the other a nut that clamps the fitting watertight against the panel. Use a rubber gasket (typically included or available separately) and do not overtighten. They are compatible with standard aquarium hose and PVC pipe of the matching ID.

Yes — you can add multiple variants (different types and sizes) to your cart in a single order. Each variant is listed as a separate line item. For large-quantity or project-specific orders, contact us to confirm availability and discuss options.
