Brass barbed hose tails, straight and 90 degree, with male threaded ends, for low-pressure hose on air, water and fluid transfer lines. The barb is sized to the hose bore and must be secured with a hose clamp.

A hose tail is a barbed spigot with a threaded end. The barbs hold the hose against pull-out; the clamp behind them provides the radial squeeze that makes the joint tight. The barb on its own is not a pressure-tight joint, which is why a tail is always ordered together with a clamp - a worm drive clip to DIN 3017-1 or SAE J1508, or an ear clamp.
The barb is selected to the inside diameter of the hose, and hose bores and their tolerances are set by ISO 1307. A tail one size out will either not enter the hose or will not grip it. Thread form is the second half of the order: BSPP parallel to ISO 228-1, BSPT taper to ISO 7-1 and NPT to ASME B1.20.1 are three different forms, and a parallel male in a taper female will screw home and still weep.
These are low-pressure fittings for air, water and fluid transfer. They are not hydraulic hose ends: a hydraulic assembly uses a crimped fitting to the ISO 12151 series, where the ferrule is swaged onto the hose at a controlled diameter. Working pressure is set by the hose and the clamp, not by the tail. As a reference figure, one supplier rates DIN 3017 9 mm band clamps at a maximum medium pressure of 45 bar in the 8 to 16 mm size and 5 bar at 140 to 160 mm, and qualifies that as depending on hose type and connection shape.
| Type | Barbed hose tails, straight and 90 degree, with male threaded ends |
|---|---|
| Material | Brass; the alloy designation is not stated by any source available |
| Hose Size | Barb selected to the hose inside diameter; hose sizes and inside-diameter tolerances are fixed by ISO 1307 |
| Thread Form | To be stated: BSPP parallel (ISO 228-1), BSPT taper (ISO 7-1) or NPT (ASME B1.20.1). The three are not interchangeable |
| Retention | The barb is not a pressure-tight joint on its own; it must be secured with a hose clamp - a worm drive clip to DIN 3017-1 or SAE J1508, or an ear clamp |
| Service | Low-pressure hose connections (air, water, fluid transfer). Hydraulic hose assemblies use crimped fittings to the ISO 12151 series, not barbed tails |
| Working Pressure | Not set by the tail. It follows the hose and the clamp: as a reference, Tubes International rates DIN 3017 9 mm band clamps at 45 bar maximum medium pressure at 8 - 16 mm falling to 5 bar at 140 - 160 mm, depending on hose type and connection shape |
