110mm Underground Drainage 90° Double Socket Bend Kayflow | UG14

Description

110mm Double Socket Bend for Underground Drainage

The double socket bend provides a nominal 90° change of direction within compatible 110mm underground drainage systems. The Kayflow UG14 features two push-fit ring-seal sockets, allowing compatible plain-ended drainage pipe or spigot-ended fittings to connect directly into either end. This compact fixed bend is suitable for foul water, surface water and general below-ground gravity drainage installations. It is commonly used where pipework requires a substantial directional change within a relatively small space.

Where to Use the Double Socket Bend

Use this fitting where a 110mm underground drainage run needs a substantial change in direction. Its compact configuration can be useful where there is insufficient space for a longer swept or long-radius bend. Typical applications include:

• Foul water drainage
• Surface water drainage
• Domestic underground drainage
• Rainwater drainage connections
• Drainage repairs and alterations
• New groundwork installations
• Changing underground pipe direction

90° Double Socket Bend Angle

Kayflow markets the UG14 as a 90° double socket bend. Detailed product information states that the actual internal directional change is approximately 88°, helping provide a slight fall through the connection while retaining the conventional 90° product description. For ordering and system identification, this fitting should therefore continue to be described as the Kayflow 90° bend.

Double Socket Bend Connections

The UG14 has two socketed ends, each containing a captive push-fit sealing ring. These sockets accept compatible plain-ended 110mm underground drainage pipe or suitable spigot-ended fittings. The double socket arrangement allows the bend to be installed directly between two plain pipe sections without requiring an additional coupler.

Installing the Double Socket Bend

Before installation, check the drainage route, alignment and required fall. Where drainage pipe is cut on site, make the cut square and remove sharp burrs from the pipe end. Inspect both sockets and sealing rings before making the joints. Remove soil, grit and other debris and make sure each seal remains correctly positioned. Apply a suitable silicone underground drainage lubricant where required. Align the pipe squarely with the socket and push the connection together without forcing the fitting sideways.

Supporting the Double Socket Bend

Provide suitable bedding beneath the bend and surrounding underground drainage pipework. The fitting should form part of a correctly supported system rather than carrying the weight of unsupported pipes. Maintain the required drainage gradient and inspect both connections before backfilling. Avoid placing sharp stones, rubble or other potentially damaging material directly against the fitting.

Double S Bend or Swept Bend?

The Kayflow UG14 is the standard compact 90° double socket bend. It should not be confused with the UG21, which is Kayflow’s separate 90° swept double socket bend. If a smoother, longer-radius change of direction is required, select the UG21 swept version instead. Where installation space is limited, the more compact UG14 may be more suitable.

UG14 and BUG14 Double Socket Codes

UG14 is Kayflow’s individual 90° double socket bend and is the correct manufacturer code when selling one fitting. BUG14 is Kayflow’s bulk-pack reference for 20 fittings and should not be used as the individual product MPN.
