Oase Rubber Connector DN110 to DN110

Oase Rubber Connector DN110 to DN110

A straight rubber coupling for compatible DN110 pond pipework and pump chamber connections

The Oase Rubber Connector DN110 to DN110 is a connecting piece for joining compatible DN110 connections in a pond installation. Oase identifies this straight connector as part 73751 and highlights its suitability for installation in pump chambers. It is useful when planning the connection between sections of a system or replacing an existing coupling of the same specification.

Check both ends of the connection before ordering. This is the DN110 to DN110 version, with the same connection designation at each end. It is different from an adaptor that changes between a threaded fitting and DN110 pipework. Matching the exact connection is particularly important when working around an existing filter, where the visible pipe size and the fitting attached to the equipment may not be identical.

Dimensions and product identification

Brand	Oase
Part number	73751
Connection designation	DN110 to DN110
Connector type	Straight rubber connector
Published overall diameter	127mm
Published length	127mm
Manufacturer application	Suitable for installation in pump chambers

The 127mm diameter is the product dimension published by Oase. Use DN110 as the connection designation when matching the fitting, and allow for the overall size when checking the space around it. These measurements serve different purposes. Do not choose a hose or pipe purely because its measurement happens to match the outside of the connector.

Choose the correct connection arrangement

Start by identifying the two parts you need to join. Note the equipment model, the existing fitting and the pipe system on the other side. If you are replacing a coupling, inspect both ends after the system has been safely isolated and drained as required. A photograph taken before dismantling can be helpful when checking the arrangement or asking us to identify a suitable replacement.

For an Oase installation using straight lengths and bends, compare our Oase DN110 Filter Discharge Pipework. Check the selected component as well as the connector so the complete run has the intended layout. A straight coupling cannot perform the same job as a bend, reducer or threaded adaptor, even where those parts are used nearby in the same filter system.

Plan access around the pump chamber

Allow enough space to reach the joint for fitting, inspection and later maintenance. A connection may be easy to assemble before the rest of the pipework is installed but difficult to reach once a pump, valve or chamber lid is in place. Consider the order of assembly and whether nearby equipment can still be removed for servicing.

Support the adjoining pipework appropriately rather than asking the coupling to carry the weight of a long unsupported run. Keep the intended alignment of both connections in mind when positioning the equipment. If the pipes do not naturally meet, correct the layout with the appropriate components instead of relying on the rubber connector to compensate for a substantial positioning error.

Replacing an existing connector

Switch off the relevant equipment and isolate the water supply to the section before dismantling it. Work out how you will manage any trapped water before loosening the old joint. Check the adjoining surfaces for damage, dirt or remnants of a previous fitting that could prevent the replacement from seating correctly.

Follow the installation instructions supplied with the connector and the equipment it joins. Leave the finished connection accessible during commissioning so you can inspect it while the system returns to normal operation. Check for movement and leakage before covering the pipework or completing the surrounding landscaping. If anything is unclear about the fitting method or suitability of the connection, resolve that before restarting the system.

Checks before ordering

• Confirm that both intended connections are compatible DN110 connections.
• Check that you need the straight DN110 to DN110 part, rather than a threaded adaptor or reducer.
• Allow for the published 127mm diameter and 127mm length within the installation space.
• Keep sufficient access around the joint for fitting and inspection.
• Check the requirements of the connected equipment before making changes to its pipework.

Help with pond pipework

When extending an existing system, it is worth drawing a simple layout showing the equipment, pipe runs and fittings you intend to use. Include the connection sizes and the available space around each component. This makes it easier to identify a missing adaptor or an awkward maintenance position before parts arrive.

If you would like help selecting the connector, contact That Pond Guy with photographs, the equipment model and measurements of the existing connection. Those details help us distinguish this Oase DN110 coupling from other rubber fittings with a similar appearance. We can then help you choose the component that suits the actual installation and the work you are planning.
