Oase Bitron Gravity Hose Adapter Kit

Hose Connection Kit for Pump-Fed Oase Bitron Gravity 55W UVC Installations

The Oase Bitron Gravity Hose Adapter Kit is a purpose-designed connection accessory for the Oase Bitron Gravity 55W UVC. It allows the gravity UVC unit to be incorporated into a pump-fed pond filtration system and provides the connection required for commonly used 1.5-inch or 2-inch flexible pond hose.

The Oase Bitron Gravity 55W is primarily designed for integration into larger pond filtration arrangements. However, not every pond or koi filtration system is configured in exactly the same way. Some installations use gravity-fed filtration, while others rely on a pump to move pond water through the UVC and connected filter equipment. This adapter kit provides a practical way to adapt the Bitron Gravity 55W for pump-fed use where the installation has been designed accordingly.

By providing compatibility with 1.5″ and 2″ hose connections, the kit makes it easier to connect flexible pond hose between the pump, UVC, and other suitable filtration components. This is particularly useful in installations where rigid large-diameter gravity pipework is not being used or where the position of the pump and UVC makes flexible hose a more practical connection method.

The adapter kit may also be used to connect compatible Oase AquaMax Eco Premium pumps to the Bitron Gravity 55W when the equipment is installed within an Oase ProfiClear Premium Individual Module. This makes it a useful accessory for specialised Oase filtration installations in which the pump, UVC, and modular filter components must be integrated into one organised water-circulation system.

Flexible hose connections can offer useful installation freedom in filter houses, pump chambers, and pond-side equipment areas. The hose can be routed according to the available space and may be easier to position around existing filters, valves, pipework, walls, and other equipment than a completely rigid connection.

The ability to choose between 1.5″ and 2″ hose also allows the connection to be matched to the correctly sized hose used by the wider pond system. The selected size should always be based on the pump outlet, desired flow arrangement, UVC requirements, and the specifications of the other connected equipment.

The kit is useful for both new installations and modifications to existing systems. It may be required when converting a Bitron Gravity 55W installation to pump-fed operation, replacing an existing hose connection, integrating a compatible AquaMax Eco Premium pump, or reorganising the filtration equipment within a pump chamber or filter house.

Using the correct Oase adapter kit also removes the need to construct an improvised connection from several unrelated reducers or hose fittings. A properly matched connection can help produce a cleaner installation and reduce the number of unnecessary joints between the pump and UVC.

The adapter kit does not replace the need for careful system planning. The complete installation should still be designed so that the selected pump, hose diameter, UVC, filter, and return pipework are compatible with one another. Hose routes should remain as direct as reasonably possible and should not contain sharp bends, compressed sections, or unnecessary restrictions.

Whether it is being used to create a new pump-fed UVC arrangement or to connect an AquaMax Eco Premium pump within a ProfiClear installation, the Oase Bitron Gravity Hose Adapter Kit provides a practical solution for adapting the Bitron Gravity 55W to compatible flexible pond hose.

Main Benefits

Converts the UVC for Pump-Fed Use

The kit allows the Oase Bitron Gravity 55W UVC to be incorporated into a compatible pump-fed water-circulation arrangement. This provides an alternative connection option for systems that are not operating solely through gravity flow.

Supports Two Common Hose Sizes

The kit accommodates 1.5″ or 2″ pond hose, allowing installers to select the appropriate connection size for the system.

Simplifies Equipment Integration

It provides a practical interface between the UVC and flexible hose, reducing the need to combine several separate adaptors.

Useful in Confined Installation Areas

Flexible hose may be easier to route through filter houses, pump chambers, and crowded pond-equipment areas where rigid pipework would be difficult to position.

Suitable for Oase Modular Installations

The adapter kit can be used when connecting an AquaMax Eco Premium pump to the Bitron Gravity 55W within a compatible Oase ProfiClear Premium Individual Module arrangement.

When to Use

Use the Oase Bitron Gravity Hose Adapter Kit when:

• Installing an Oase Bitron Gravity 55W in a pump-fed system
• Connecting 1.5″ flexible hose to the UVC
• Connecting 2″ flexible hose to the UVC
• Integrating a compatible AquaMax Eco Premium pump
• Installing equipment within a ProfiClear Premium Individual Module
• Replacing an existing Bitron Gravity hose-adapter connection
• Modifying an established pond filtration system
• Moving the UVC or pump to a different position
• Creating a flexible connection inside a filter house
• Avoiding an improvised multi-adaptor hose arrangement
• Building a cleaner pump-to-UVC plumbing route

How It Works

The adapter kit is fitted to the appropriate connection point on the Oase Bitron Gravity 55W UVC.

A compatible 1.5″ or 2″ flexible pond hose is then connected to the adapter according to the selected system layout.

In a pump-fed installation, the pond pump moves water through the connected hose and towards the UVC. Water then passes through the Bitron Gravity unit before continuing to the next compatible component in the filtration system.

When used within an Oase ProfiClear Premium Individual Module arrangement, the adapter kit can help form the connection between a compatible AquaMax Eco Premium pump and the Bitron Gravity 55W UVC.

The exact sequence of the pump, UVC, filtration components, valves, and return pipework should follow the relevant Oase installation instructions.

Pump-Fed Installation Overview

A typical compatible arrangement may involve:

Pond or pump chamber → AquaMax pump → flexible hose → adapter kit → Bitron Gravity 55W UVC → filtration or return system

The exact layout may differ according to the pond design and filtration equipment. Confirm the approved installation sequence before connecting or operating the system.

Hose Size Selection

The kit allows either a 1.5-inch or 2-inch hose connection.

The correct size will depend on:

• The pump’s outlet connection
• The hose already used in the system
• The required system flow
• The distance between the pump and UVC
• The number of bends in the hose route
• The connection requirements of the filtration equipment

A larger hose may reduce unnecessary restriction in some installations, but the complete system must be checked for compatibility before selecting the hose size.

Installation Guidance

1. Switch off and isolate the pump and UVC power supply.
2. Confirm that the UVC is the Oase Bitron Gravity 55W model.
3. Plan the complete pump-to-UVC hose route.
4. Select either a compatible 1.5″ or 2″ hose.
5. Inspect the hose and connection surfaces for damage or debris.
6. Fit the adapter components according to the Oase instructions.
7. Push the hose fully onto the appropriate connection.
8. Secure the hose using suitable connection components where required.
9. Avoid twisting or placing excessive weight on the UVC connection.
10. Route the hose without sharp bends or compressed sections.
11. Support long or heavy hose runs where necessary.
12. Check every connection before restoring power.
13. Run the pump and inspect the system for leaks.
14. Only operate the UVC when the unit is correctly installed and water is flowing as required.

Important Installation Considerations

• Confirm compatibility before dismantling the existing system.
• Do not assume the kit fits other Bitron UVC models.
• Ensure the pump is suitable for the intended filtration arrangement.
• Avoid reducing the hose unnecessarily immediately before the UVC.
• Keep the hose route as short and direct as practical.
• Do not allow the hose to kink behind filtration equipment.
• Avoid placing strain on the UVC housing.
• Follow all electrical and installation instructions supplied with the UVC.
• The UVC should be installed where it can be accessed for maintenance.
• Check the system for leaks after any hose adjustment.

Related Oase DN Pipework

This adapter kit is useful when planning gravity-fed Bitron installations alongside larger Oase pipework. For complete installations, also check whether the return route requires DN110 discharge pipework or an eccentric rubber connection.
