Prestwich Hydroponics® 25mm IWS Fittings – 6918870270037

These are all components of the IWS Hydroponics system. The Barbed Straight Piece, Tee Piece, and Elbow Piece are universal fittings that can be used to extend, terminate, or turn the piping of the system. They have barbs on one end to hold them securely in the piping and a screw end to attach inside the pots. The Plastic Nut and Rubber Washer are used in conjunction with the 25mm fitting and pot to ensure a tight seal. The Rubber Washer should be placed on either side of the fitting, and the Plastic Nut is used to tighten the connection.
