Oase Rubber Connection 2″ Female Threaded – DN110 Eccentric

Oase Rubber Connection 2″ Female Threaded – DN110 Eccentric

Flexible Eccentric Adaptor for Oase ProfiClear Pump-Chamber Pipework

The Oase Rubber Connection 2″ Female Threaded – DN110 Eccentric is a genuine Oase connection component designed to create a practical transition between equipment with a compatible 2-inch male threaded connection and DN110 pipework. It is especially suitable for use within Oase ProfiClear pump-chamber installations, where correctly sized and properly aligned pipe connections are essential for creating an organised pond-filtration system.

This specialist fitting combines a 2″ female-threaded inlet with a larger DN110 outlet, allowing two different connection formats to be joined within one compact component. It can be used when integrating compatible pumps, outlets, valves, filter components, or existing threaded equipment into a DN110 pipework system.

The eccentric design means the two connections are arranged with an offset rather than being positioned directly through the same centre line. This makes the fitting particularly useful where the connected equipment and DN110 pipework do not align perfectly. The offset configuration can help installers create a more practical route between components without relying on an unnecessarily complicated combination of rigid adaptors.

In pond-filter rooms and pump chambers, pipework is often installed in limited spaces where filters, pumps, valves, drains, and other equipment must be positioned close together. A conventional straight, concentric fitting may not always suit the available alignment. The Oase eccentric rubber connection provides a convenient solution for installations requiring a change in both connection size and centre position.

Its rubber construction allows a degree of flexibility during installation, making it easier to position between compatible components than a completely rigid connector. This can be helpful when making minor alignment adjustments or replacing an existing fitting within an established filtration system.

The fitting is supplied with three stainless-steel hose clips, providing the securing components required for its rubber connection points. When installed correctly, the clips help hold the fitting securely around the compatible pipework or equipment connection.

With an overall listed size of approximately 75mm in length and 125mm in diameter, the connector remains compact enough for installation within compatible pump chambers and filtration areas. Its relatively short form helps minimise the amount of extra space required between the connected equipment and DN110 pipework.

The Oase Rubber Connection may be used during the original installation of an Oase ProfiClear system or when repairing, replacing, or modifying an existing pipework arrangement. It is useful when a previous connector has become damaged, when equipment is being repositioned, or when a filtration system is being upgraded to include different components.

Because the product is manufactured for this specialised pipework application, it provides a more suitable option than attempting to create the transition using several unrelated fittings. Using one purpose-designed eccentric connector can help create a cleaner, more compact, and easier-to-manage installation.

The connection can also make future maintenance more manageable. A rubber fitting secured by hose clips may be easier to access and remove than a permanently bonded rigid connection, depending on the complete installation. This can be helpful when pumps, valves, or chamber components need to be inspected, serviced, or replaced.

Whether used for a new Oase ProfiClear pump-chamber installation, an equipment replacement, or a filtration-system modification, the Oase 2″ Female Threaded to DN110 Eccentric Rubber Connection provides a practical way to join compatible threaded equipment to large-diameter pond pipework.

Benefits of the Eccentric Design

The eccentric arrangement places the smaller threaded connection and larger DN110 connection on offset centre lines. This can be useful when:

• The equipment outlet does not align directly with the DN110 pipe
• The pipework needs to run slightly higher or lower than the threaded connection
• Limited space prevents the use of multiple rigid adaptors
• A compact transition between two connection sizes is required
• Existing filtration equipment is being repositioned
• A cleaner and more direct pipe route is preferred

The fitting should be rotated into the most suitable orientation before the hose clips are fully tightened.

When to Use

• Connecting compatible equipment to DN110 pond pipework
• Installing pipework inside an Oase ProfiClear pump chamber
• Replacing an existing eccentric rubber connector
• Connecting a 2″ male-threaded outlet to a DN110 system
• Correcting a minor alignment difference between components
• Modifying an established pond-filtration installation
• Repositioning pumps, valves, or chamber equipment
• Creating a compact pipework transition in a limited space
• Repairing damaged or unsuitable filtration pipework
• Upgrading an existing Oase ProfiClear system

How It Works

The 2″ female-threaded end is connected to equipment with a compatible 2″ male thread.

The larger end of the fitting is positioned over the compatible DN110 connection or pipework. The eccentric connector should be rotated until its offset provides the most suitable alignment between the two components.

Once the fitting has been positioned correctly, the supplied stainless-steel hose clips are placed around the appropriate connection areas and tightened evenly.

The clips should be secure enough to hold the fitting firmly without being overtightened or damaging the rubber connector.

After installation, the complete system should be inspected during operation to confirm that the connection is correctly seated and that there are no visible leaks or movement.

Installation Guidance

• Confirm that the threaded equipment connection is 2″ male
• Confirm that the larger pipework connection is DN110
• Inspect the rubber fitting before installation
• Make sure all connection surfaces are clean
• Position the eccentric offset in the required direction
• Start the threaded connection carefully
• Avoid cross-threading the equipment connection
• Position the hose clips correctly before tightening
• Tighten each clip gradually and evenly
• Avoid overtightening or deforming the rubber
• Support connected pipework where necessary
• Test the complete connection before normal operation

Related Oase DN Pipework

This eccentric rubber connection is most relevant to larger Oase DN110-style pipework and ProfiClear/Bitron gravity installations. Check the exact connection size before ordering, especially where 2" threaded fittings, DN110 discharge pipework and gravity-fed equipment are being combined.
