Hose Tail

What is a hose tail?

A hose tail is a fitting with a threaded end for connecting to a pipework fitting and a ribbed (barbed) tail on the other end that inserts into the hose. It is used to attach a hose to a pump outlet, tap, valve, or tank connection. Once the hose is pushed onto the tail, it is secured with a clamp to produce a leak-free, firm connection. It is an essential component in many applications from garden irrigation to water transfer.

Selection criteria

• Thread size: Must match the thread size of the tap, valve, or pump outlet to which it will be connected.
• Tail diameter: Must suit the inner diameter of the hose; a tail that is too narrow will cause leaks, while one that is too wide will prevent the hose from fitting.
• Material: Yellow (brass) hose tails are corrosion-resistant and long-lasting.
• Swivel head: Allows the hose to be connected without twisting.

The 1/2 inch models in this category are the most commonly used size in domestic and garden applications.

Installation recommendations

Dipping the hose end in warm water makes it easier to push onto the tail. The hose should be pushed all the way to the end of the tail and secured with a hose clamp positioned over the ribs. On pressurized lines, using two clamps instead of one reduces the risk of the connection coming apart. PTFE tape should be used on the threaded side to ensure a leak-free seal.

Applications

Typical applications for hose unions include connecting hoses to pump and engine-driven pump outlets, transferring water from tanks and barrels, garden and greenhouse irrigation, and filling tankers. Quick-connect fittings can also be used where connections are frequently disconnected and reconnected.

Frequently asked questions

Which hoses does a hose union fit?

The tail diameter must match the inner diameter of the hose; check the size stated in the product information.

What should I do if the union is leaking?

Renew the PTFE tape on the threaded side, tighten the clamp on the hose side, or add a second clamp.

Can a hot water hose be connected?

Brass unions are suitable for hot water; the hose must also be rated for hot water.

Which union fits a pump outlet?

Select based on the pump's outlet thread size and the diameter of the hose you will be using.

What do you recommend for a disconnectable connection?

For connections that are frequently disconnected, cone unions or swivel-head models offer convenience.

Does a hose clamp need to be purchased separately?

Hose unions generally do not include a clamp; you will need to obtain a clamp suited to the hose diameter separately.
