Adapter Female Hose Thread to 0.25 inch ID Tubing
Female Garden Hose to 0.25"ID Tubing Adapter
This adapter connects garden hose to 0.25" inside diameter tubing. At 10psi, 100 feet of 0.25"ID hose will discharge about 0.5 gallons per minute. (http://www.engineeringtoolbox.com/water-discharge-hose-d_1524.html).
We use this adapter and related 0.25ID tubing in our Universal Connector kits for its flexibility and ease of use. A hose washer is included with this product.
