Clear PVC Fittings: Elbows,TEEs,Couplings,Caps,Unions,Ball Valves,Straight,Cross

Match the fitting size to the outer diameter (OD) of your PVC pipe. For example, if your pipe measures 25mm OD, select the 25mm variant. Standard metric uPVC pipe sizes are 20, 25, 32, 40, 50, 63, 75, 90, and 110mm. If you are unsure, measure the pipe OD with calipers before ordering.

Clear PVC fittings are suitable for low-to-moderate pressure applications such as aquarium return lines, hydroponics irrigation, and gravity-fed domestic water systems. Exact pressure ratings vary by size and wall schedule — contact us to confirm suitability for your specific operating pressure before use in pressurized mains supply lines.

Rigid PVC has good resistance to dilute acids, alkalis, salt solutions, and many common household chemicals. It is widely used in aquarium and hydroponics plumbing for this reason. It is not recommended for concentrated solvents, aromatic hydrocarbons, or chlorinated solvents, which can soften or craze the material.

Use a standard PVC solvent cement (PVC glue) rated for rigid uPVC pipe. Apply primer if required by your local plumbing code, then apply cement to both the pipe end and the fitting socket, insert, and hold for 30 seconds. Allow the joint to cure fully before pressurizing — typically 1–2 hours for light service, 24 hours for full pressure.

No. These fittings are designed specifically for standard metric rigid uPVC pipe using solvent-weld assembly. CPVC requires its own dedicated cement and has different dimensional tolerances. ABS pipe is not compatible with PVC solvent cement. Push-fit (compression) systems do not use glued fittings at all. Always match fitting material and connection type to your pipe system.

A Union Joint consists of three pieces — two solvent-welded sockets and a threaded collar — that allow you to disconnect and reconnect the joint without cutting the pipe. This is ideal for equipment that needs periodic removal for cleaning or maintenance, such as pump housings, filters, or UV sterilizers. A standard straight coupling is a permanent, non-serviceable joint.

The clear PVC Ball Valve provides inline flow shut-off with a quarter-turn handle. It is solvent-welded into the pipe run like any other fitting. Use it wherever you need to isolate a section of pipework for maintenance, control flow to individual branches, or drain a line. The transparent body lets you see whether the ball is open or closed and whether flow is present.

Clear PVC can yellow gradually with prolonged exposure to direct UV sunlight. For outdoor installations, consider UV-protective pipe lagging or routing pipework away from direct sun. For indoor aquarium, hydroponics, or enclosed plumbing applications, discoloration is typically not a concern under normal service conditions.
