Thru hull fittings are our standard fittings for connecting the feed line to any flood and drain tables or trays. They come in a few different outside diameter barbs for secure connection to the 1/2″ tubing most commonly used in flood and drain gardens. They can also double as drain fittings when a Mushroom Syphon Valve is not required.
Thru hull fittings are also a better choice for plumbing pails together when constructing recirculating deep water culture gardens when compared to gromets and barbed fittings. This gasketted fitting has a nut which can be tightened to provide a secure and leak free seal.
* Gaskets are always included with Thru Hull fittings.
