► Hardie Hose | Nut & Tails

Reliable Brass Connections for Hose & Equipment

Connecting a threaded outlet to flexible hose? Hardie Hose | Nut & Tails provide a direct brass connection between compatible equipment & hose, with straight & reducing configurations suited to pumps, water transfer, agricultural equipment, workshop maintenance & industrial hose assemblies.

Choose from 14 brass nut & tail fittings, including straight sizes from 12 mm to 100 mm plus selected reducing configurations where the equipment connection & hose require different nominal sizes. For a better match, check both ends before ordering — identify the nut connection first, then confirm the hose-tail size.

► 14 brass nut & tail fittings
► Straight sizes from 12 mm to 100 mm
► Selected reducing nut-to-tail configurations
► Options for small through to large-diameter hose assemblies
► Direct equipment-to-hose connection
► Hardie Hose components for trade & industrial applications

Need a different connection? Use the job itself to narrow the choice.

Quick selection check: know the nut connection, hose-tail size & application. A 25 mm straight nut & tail & a 25 mm nut x 12 mm tail share a nut-side size, but they're intended for different hose connections.

What Is a Hardie Hose Nut & Tail?

One fitting handles the change from a compatible equipment connection to flexible hose. The nut forms the connection at the equipment or mating-fitting end, while the tail provides the interface for the hose.

A typical arrangement looks like:

Equipment connection → nut & tail → flexible hose

Where the correct configuration is available, this provides a compact alternative to building the same transition from several separate components.

The fitting still needs to be considered from both directions. The nut side must correspond with the mating connection & the tail must suit the hose being installed.

How Do I Choose the Right Nut & Tail?

Start with the equipment rather than the fitting shelf. The existing connection gives you one fixed reference point, while the hose provides the second.

Before comparing fittings, establish:

► Equipment-side connection
► Required nut size
► Hose type
► Required hose-tail size
► Straight or reducing configuration
► Condition of the mating connection
► Intended application

If you're replacing an existing fitting, keep the old nut & tail until the replacement has been positively identified.

Straight Brass Nut & Tails

When the required nominal dimensions correspond across the connection, a straight nut & tail is the logical place to start.

The current range includes:

With sizes extending from 12 mm through to 100 mm, the collection covers considerably different hose applications. Confirm the complete connection rather than selecting from size alone.

For alternative hose-side configurations, compare Hardie Hose | Hose Tails.

When Do You Need a Reducing Nut & Tail?

Sometimes the equipment connection & hose simply aren't the same nominal size. A reducing nut & tail provides that transition within one fitting where the configuration is suitable for the assembly.

Current reducing options include:

► 20 mm nut x 12 mm tail
► 25 mm nut x 12 mm tail
► 25 mm nut x 20 mm tail
► 32 mm x 25 mm
► 50 mm x 38 mm

Take the 25 mm products as an example. Depending on the hose connection required, you could be comparing:

25 mm straight nut & tail

25 mm nut x 20 mm tail

25 mm nut x 12 mm tail

The equipment-side dimension alone therefore isn't enough to identify the correct product.

Straight vs Reducing Nut & Tails

Not sure which configuration belongs in the assembly? Compare what's entering the fitting with what's leaving it.

Don't reduce the hose simply because a smaller size is easier to route. Any change in dimensions should make sense for the equipment & complete hose system.

Pump Connections – Start at the Outlet

A pump gives you a useful fixed starting point: its existing connection. Identify that first, then work downstream through the nut & tail, hose & remaining components.

A straightforward arrangement could be:

Pump → mating connection → nut & tail → hose → outlet

More involved systems may also contain valves, couplings, additional hose sections & delivery equipment.

Following the flow path from component to component makes mismatched sizes easier to spot before the system goes back together.

For suitable washdown setups, Hardie Hose | Washdown Guns provides purpose-specific equipment for the working end of the hose.

Is a Reducing Nut & Tail a Universal Reducer?

No — treat it as a specific hose-connection component rather than a general solution for changing any two sizes.

A 50 mm x 38 mm nut & tail, for example, provides a particular transition between its nut side & hose-tail side. Both ends still need to correspond with the components they're joining.

Before choosing a reducing configuration, ask why the dimensions differ & whether that combination belongs in the intended system.

Nut & Tail vs Hose Joiner vs Hose Tail

The easiest distinction comes from looking at what's on either side of the component.

If you're reconnecting two compatible hose sections after removing a damaged area or adding length, Hardie Hose | Hose Joiners is the more relevant range.

Why Brass?

Brass construction is used across the current Hardie Hose Nut & Tails collection. That gives the range a consistent fitting material from the smaller 12 mm options through to substantially larger 75 mm & 100 mm connections.

Material is only one part of selection, however.

A brass fitting with the wrong nut connection or hose-tail dimension is still the wrong component. Size, configuration, hose & application need to be considered together.

Larger Hose Connections Need the Same Careful Matching

A 100 mm hose assembly is a very different proposition from a 12 mm connection, even though both products belong to the same fitting family.

At the larger end, the collection includes 63 mm, 75 mm & 100 mm straight brass nut & tails for compatible large-diameter assemblies.

That makes precise identification especially worthwhile.

Rather than recording “Hardie Hose nut & tail”, note the actual configuration you're working with — for example, 63 mm brass nut & tail or 50 mm x 38 mm reducing nut & tail.

Clear identification becomes particularly useful when maintenance teams are ordering components for several machines at once.

Check the Hose While the Fitting Is Off

Once the old component has been removed, you have an ideal opportunity to inspect an area of hose that's normally hidden or difficult to examine.

Look for:

► Cracking
► Hardening
► Cuts
► Abrasion
► Deformation
► Damage around the old tail
► Heat exposure
► Chemical deterioration
► Previous repairs
► Repeated wear close to the connection

A replacement fitting shouldn't distract from a hose that's already approaching the end of its useful service life.

Read the Wear Before You Replace the Part

Damage around the old fitting can reveal how the assembly behaves when it's actually working.

Wear on one side of the hose may point towards contact with machinery or surrounding structures.

A pronounced bend immediately behind the fitting can indicate poor routing.

A hose that's constantly pulled tight may be loading the connection whenever equipment moves.

Repeated failure in the same location deserves investigation rather than another identical repair.

Take a Photo Before Pulling the Assembly Apart

A quick photo can preserve details that become surprisingly difficult to remember once the fittings are sitting loose on a workbench.

Capture:

► Fitting orientation
► Hose route
► Connected equipment
► Nearby components
► Visible markings
► Position of supporting hardware

Keep the removed component with the hose it came from until the replacement is confirmed.

Give the Hose a Natural Route

Correct fitting selection won't compensate for a hose being forced into a poor position.

Once assembled, check how the hose leaves the tail.

Avoid unnecessary:

► Sharp bends immediately behind the fitting
► Side-loading
► Stretching
► Twisting
► Contact with sharp machinery edges
► Abrasion against floors or frames
► Loose loops that create snag points

Consider what happens when the equipment moves, not just how the connection looks while everything is stationary.

Extending the Hose Somewhere Else in the System?

A nut & tail solves the equipment-to-hose transition, but another section of the assembly may call for a completely different fitting.

When two compatible hose sections need to continue inline, use the appropriate Hardie Hose | Hose Joiners.

Where regular connection & disconnection is required, investigate Quick Couplers & Connectors.

Matching each connection to its actual job can produce a cleaner assembly than trying to make one fitting family solve every transition.

What About Compressed-Air Equipment?

A fitting that physically connects isn't automatically suitable for every compressed-air installation. Pneumatic systems should use hose, fittings & components appropriate to their equipment & operating requirements.

Four Checks Before the Spanners Come Out

Confirm Both Ends

One correct measurement isn't enough. Identify the nut connection & hose-tail requirement separately.

Inspect the Mating Component

A new fitting can't repair an existing damaged connection. Check the equipment side before installation.

Examine the Hose

Pay particular attention to the section immediately behind the old fitting. Hidden deterioration can become obvious once the assembly is apart.

Check the Route

Imagine the hose under normal movement. Make sure the new connection won't immediately be subjected to unnecessary pulling, bending or abrasion.
