Choose from a selection of genuine 25mm IWS components that are perfect for upgrading your system or replacing lost or damaged parts.

Barbed Straight Piece

A Universal Straight that fits onto the pots of your IWS Hydroponics system. The barbs on one end of the Straight Piece hold it very securely in the piping. The screw end attaches securely inside your pots.

Barbed Tee Piece

The Universal Tee Piece fits onto the middle of a piping-run to extend the pipe. The barbs on one end of the Universal Tee-joint hold it very securely in the piping. The screw end attaches securely inside your pots.

Barbed Elbow Piece

The Universal Elbow fits onto the end of piping run to terminate the pipe and provide a convenient way of “turning the corner” into the last Outer Pot on your IWS Hydroponics system. The barbs on one end of the Universal Elbow hold it very securely in the piping. The screw end attaches securely inside your pots.

Plastic Nut

The IWS 25mm Plastic Nut should be used with your IWS 25mm fitting, washer and pot to ensure a tight seal.

Rubber Washer

The IWS 25mm Washer should be used on either side of your IWS 25mm fitting and pot to ensure a tight seal.

Individual Pot Filter

The inline IWS flood and drain-drain filter is 110 mm long and has a 25 mm female thread that attached to a 1" diameter male drain hose tail or a 16 mm reducing grommet for older 16 mm systems.

The filter sits inside the pot and acts to filter out large particles, stopping them from returning to the reservoir. The filter is a hard-wearing plastic cage with a copper mesh that repels roots, limiting their ingress.
