Irritec FHT End Cap Flush Valve

Add To Project Add To Compare

Use this flush valve cap to turn the Perma-Loc end caps into a flush valve. Simply remove the standard cap and replace with this flush valve. This item has standard 3/4" female hose thread connection. This low pressure valve allows water to flush out at system start-up with as little as 0.66 GPM (39.6 GPH) flow required to close the valve. The valve opens at shutdown when system reaches 0.87 PSI.

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.
