Nukatap – SS

NukaTap SS Stainless Steel Beer Tap is an advanced forward-sealing draught faucet developed to improve first-pour performance, sanitation, tap movement and long-term reliability. It replaces the bulky internal components found in many traditional beer taps with a streamlined NukaShuttle that has lower thermal mass and a seamless sealing surface.

The result is a smooth-operating stainless steel tap that helps reduce foam, limits areas where residue may collect and works with a broad range of kegged beverages.

It is a practical upgrade for kegerators, beer fonts, home bars, keezer builds and custom draught systems.

Reduced First-Pour Foam

Beer taps often become warmer than the beverage lines and keg because they sit outside the refrigerated cabinet or font. When cold, carbonated beer first enters a warm tap body, carbon dioxide can break out of solution and create excess foam.

The NukaTap design reduces the thermal mass of the internal shuttle and tap assembly. Less material needs to be cooled by the first pour, helping reduce the common burst of foam experienced with heavier, older tap designs.

First-pour performance still depends on:

• Beverage temperature
• Font temperature
• Keg pressure
• Carbonation level
• Beer line length
• Ambient temperature
• Tap cleanliness

A correctly balanced and chilled draught system will provide the best results.

Generation 2 Over-Moulded NukaShuttle

The Generation 2 NukaShuttle is an over-moulded, single-piece component built around a durable internal skeleton.

Unlike traditional shuttle designs that rely on separate O-rings seated on metal parts, the NukaShuttle forms the sealing surface directly into the component.

This provides several benefits:

• Fewer separate sealing parts
• Reduced thermal mass
• Smooth tap action
• Fewer crevices that can hold residue
• Improved chemical resistance
• Less reliance on moving O-rings
• Easier routine cleaning

The one-piece construction also reduces the risk of seals shifting or binding as the tap ages.

Improved Laminar Flow

The streamlined NukaShuttle is shaped to guide the beverage smoothly through the faucet.

Improved laminar flow reduces unnecessary turbulence inside the tap. This can help highly carbonated beverages pour more steadily when the complete system is balanced correctly.

Potential benefits include:

• More controlled flow
• Reduced foaming
• Smoother pours
• Better glass presentation
• Less turbulence near the outlet
• Improved performance with carbonated drinks

Flow quality still depends on the pressure, temperature and resistance throughout the entire draught system.

Forward-Sealing Design

The NukaTap SS Stainless Steel Beer Tap closes at the front of the faucet, close to the dispensing nozzle.

This differs from traditional rear-sealing taps, where the internal body can drain after use and leave a moist cavity exposed to air.

A forward-sealing design helps:

• Keep more of the tap interior filled with beverage
• Reduce exposure to airborne contaminants
• Limit sticky residue inside the rear tap body
• Reduce tap sticking between uses
• Improve cleaning access
• Maintain smoother operation

Regular cleaning is still essential. No beer tap is maintenance-free.

What Is a Rear-Sealing Tap?

A traditional rear-sealing tap closes the beverage flow near the rear of the faucet body.

After the tap is closed, beverage remaining in the front section may drain through a small vent. This can leave a warm, damp cavity inside the faucet.

That environment may encourage:

• Dried beverage residue
• Sticky internal surfaces
• Wild yeast growth
• Bacterial contamination
• Unpleasant flavours
• Tap sticking

Forward-sealing designs reduce this exposed internal space by closing the beverage flow closer to the outlet.

Sanitary Single-Piece Shuttle

Traditional taps can contain separate seals fitted onto metal components. The small joins between these parts may trap beverage solids or become harder to clean.

The seamless NukaShuttle removes many of these joins by forming the sealing material over a single internal structure.

This design can help reduce:

• Small residue-trapping gaps
• Difficult-to-clean sealing surfaces
• Loose or displaced O-rings
• Unnecessary internal components
• Maintenance complexity

The tap should still be disassembled and inspected as part of a regular cleaning schedule.

Long-Life Sealing Material

The NukaShuttle uses a durable thermoplastic vulcanisate sealing matrix designed to tolerate a broad range of beverage and cleaning conditions.

This is particularly useful for systems dispensing:

• Beer
• Cider
• Sour beer
• Kombucha
• Ginger beer
• Soft drinks
• Other acidic kegged beverages

Some rubber seals can degrade when repeatedly exposed to acidic drinks, alkaline cleaners or sanitising chemicals. The NukaTap sealing system is designed for improved resistance under suitable use and cleaning conditions.

Always follow the recommended chemical concentration and contact time. Excessively strong cleaning solutions can still damage equipment.

Smooth Gliding Action

Some older beer taps use metal-on-metal internal movement, which can become rough or stiff as components wear.

The NukaTap is designed to provide a smooth gliding action without the raspy feel found in some conventional faucets.

This can improve:

• Pouring comfort
• Tap control
• Long-term usability
• Handle movement
• Daily operation
• Resistance to wear

Smooth operation is particularly useful when using larger or heavier tap handles.

Compatible with Long Tap Handles

The tap body uses a 2.5-degree reverse handle angle.

This small angle creates additional clearance and helps support a wider variety of tap handles, including:

• Long tap handles
• Heavy handles
• Branded handles
• Custom handles
• Decorative bar handles
• Tall homebrew labels

The reverse angle helps reduce the chance of a long handle interfering with the font, wall or nearby tap.

Always make sure the font and mounting area provide adequate clearance.

Suitable for Many Draught Systems

The tap can be installed on compatible:

• Kegerators
• T-bar fonts
• Beer towers
• Keezer collars
• Wall-mounted shanks
• Home bars
• Commercial-style draught setups
• Portable dispensing systems

A compatible shank, collar and mounting hardware may be required.

Check the product thread and shank compatibility before installation.

Suitable Beverages

This stainless steel tap may be used with many compatible kegged beverages, including:

• Lager
• Pale Ale
• IPA
• Stout
• Porter
• Cider
• Ginger beer
• Sour beer
• Kombucha
• Sparkling water
• Soft drinks
• Premixed kegged beverages

Sweet or acidic drinks require more frequent cleaning than standard beer.

Avoid leaving sugary beverages sitting in the tap for long periods without cleaning.

General Installation

A typical installation process includes:

1. Confirm that the tap and shank threads are compatible.
2. Clean and sanitise the tap before first use.
3. Fit the tap to the shank.
4. Tighten the collar with a suitable tap tool.
5. Attach the chosen tap handle.
6. Connect the beverage line.
7. Check all seals and connections.
8. Flush the system with sanitiser or clean water as required.
9. Test the tap with a chilled beverage.
10. Adjust the complete draught system if the pour is too fast or foamy.

Do not overtighten the tap collar or handle.

Balancing the Draught System

A premium tap cannot compensate for an unbalanced keg system.

Pour performance depends on:

• Keg temperature
• Carbonation pressure
• Serving pressure
• Beverage line length
• Internal line diameter
• Tap height
• Beverage type
• Font cooling

If the pour is too fast or foamy, check the temperature and line resistance before reducing pressure.

Repeatedly lowering pressure may cause the beverage to lose carbonation over time.

Cleaning the Tap

Clean the tap before first use and at regular intervals.

Recommended cleaning times include:

• After each keg
• Between different beverages
• After serving sweet drinks
• After serving kombucha or sour beer
• Before extended storage
• Whenever the tap feels sticky
• Whenever flavour or aroma changes

A general cleaning process includes:

1. Disconnect and depressurise the beverage system.
2. Remove the tap using a suitable faucet tool.
3. Disassemble the tap carefully.
4. Soak compatible parts in correctly diluted beer line cleaner.
5. Clean small internal surfaces with a soft brush.
6. Rinse thoroughly.
7. Inspect the shuttle and seals.
8. Reassemble and sanitise.
9. Reinstall and test for leaks.

Follow the manufacturer’s cleaning and maintenance instructions.

Cleaning Chemical Compatibility

The sealing material is designed to tolerate a wide range of normal draught cleaning conditions. However, correct chemical use remains important.

Always:

• Measure cleaner accurately
• Follow the recommended dilution
• Observe the contact time
• Rinse where directed
• Avoid mixing chemicals
• Wear suitable protective equipment
• Do not leave parts soaking indefinitely

Using excessively concentrated caustic or acid can damage taps, seals, tubing and other draught components.

Reducing Tap Sticking

Forward-sealing taps generally experience less sticking than rear-sealing designs because less beverage is left exposed inside an empty front cavity.

To maintain smooth operation:

• Clean the faucet regularly
• Rinse after sweet beverages
• Do not allow residue to dry inside the nozzle
• Inspect the shuttle during servicing
• Avoid unsuitable lubricants
• Use only compatible replacement parts

A tap that becomes stiff should be cleaned and inspected rather than forced.

Improving the First Pour

To further reduce first-pour foam:

• Keep the keg fully chilled
• Insulate the beer font
• Use tower cooling where needed
• Keep beverage lines cold
• Avoid direct sunlight on the tap
• Balance the beverage line
• Use the correct serving pressure
• Clean the faucet regularly

In hot environments, the external tap body may still warm between pours. Font cooling can provide additional improvement.
