Check the listing for details. Tempo Compression Tubing x FHT Tee Adapter. Condition: New. Listed at 7.96 USD. Garden Hose Threads (GHT, FHT, MHT) are unique in that they make the water-tight seal with a flexible washer between the two connection pieces. Thread seal tape is not recommended since it can inhibit the full threading together of the pieces, thus not allowing a tight leak-proof seal. GHT are not compatible with NPT or IPT/IPS fittings commonly found in iron pipe or PVC water systems. This 3/4" FHT (Female Hose Thread) Swivel Tee compression fitting with black inserts is compatible with our 1/2" poly tubing with .700" outside diameter. The FHT swivel connection easily attaches to your outdoor spigot or garden hose to run our 1/2" (.700" OD) poly tubing in two directions from one connection.Often used by irrigation contractors, compression fittings are very economical and do not require clamps or gluing. Because of this, the fittings can be more difficult to install and are not removable/reusable. Compression fittings install over the poly tubing and are size specific for your tubing outside diameter.
