This is a Brass Male Threaded BSP Hosetail, which has a male tapered BSP thread with a barbed hose tail. It is manufactured from a solid brass for the use with air, water, gas and other types of fluids. We have a large range of sizes to accommodate hoses from 1/8" (~3mm) Hose ID to 3" (~75mm) Hose ID. Please select the sizes you require from the drop down boxes above.
Note: "Hose Internal Diameter (Bore)" measurement refers to the hose ID that the hose tail end is made to fit. Please use the inch size as a more accurate measurement.
IMPORTANT - BSP Threads are not measured at their width, read below for more details.
Please note that the BSP measurements are NOT the physical measurement of the thread diameter of the fitting. For example a 1/8" BSPT Male thread would actually measure 9.5mm or 0.37". For more information, please see the table below.
If you are still unsure about which thread size you need, please don't hesitate to get in contact with us through eBay.
