A 300mm flexible tap connector hose with 15mm compression ends at both sides. WRAS approved, stainless steel braided over EPDM, rated to 15 bar and 70°C. Suits most kitchen and bathroom taps where a bit of flex makes all the difference.
A good tap connector hose does one job quietly and without complaint. This 300mm flexible hose tap connector runs from 15mm to 15mm compression fittings, giving you a reliable, pressure-tested link between your tap tail and the isolation valve or supply pipe below. It is the kind of fitting that saves you half an hour of awkward pipework when the geometry under a sink is anything but straight.
The hose is built from EPDM rubber core with stainless steel braiding over the outside. The EPDM gives it flexibility and long-term resistance to both hot and cold water, while the stainless braid keeps the hose from ballooning under pressure. Working pressure is rated to 15 bar, which is well above anything a typical domestic or light commercial supply will throw at it. Maximum temperature is 70°C, making it suitable for both hot and cold supplies without needing separate hoses for each.
Both ends are 15mm compression fittings to BS EN 1254-2, so they work with standard 15mm copper or compatible plastic pipework. No special tools needed, no push-fit adapters, no drama. You tighten the compression nuts by hand first, then use a spanner to snug them up. The 300mm length gives enough slack to work with taps that sit a little off-centre or where the supply pipe enters from an awkward angle.
Where a Flexible Tap Connector Hose Earns Its Keep
Under-sink plumbing is rarely as tidy as the plans suggest. Supply pipes come up in slightly the wrong place, tap tails are a touch short, and rigid pipe just will not bend far enough without looking like it is fighting itself. A flexible hose tap connector solves all of that at once. Rather than cutting, bending, and re-soldering copper to hit the right angle, you connect the compression end to your supply, route the hose to the tap tail, and you are done.
This connector is particularly useful during tap replacements, where the existing supply pipe stub may not line up exactly with the new tap. It is also the sensible choice when fitting taps in tight vanity unit cabinets or under kitchen sinks with pull-out drawers that leave very little working space. Plumbers use them as standard on virtually every tap fit-out because rigid connections to tap tails are awkward, time-consuming, and offer no vibration tolerance at all.
Approval and Compliance
The connector carries WRAS approval, meaning it has been assessed and confirmed as suitable for use with potable water in the UK. This matters if you are working on a property where water fittings regulations apply, which in practice means most plumbing work in England and Wales. The compression ends conform to BS EN 1254-2, keeping the fitting within the standard expected by building control and most main contractors.
At under a pound, keeping a few of these in the van is a no-brainer. They weigh nothing, take up no space, and will save you a trip to the merchant mid-job more often than you might expect.
Pro Tip: When tightening the compression ends, do not overtighten. Nip up finger-tight first, then add no more than one and a quarter turns with a spanner. Overtightening compresses the olive too far and risks splitting the fitting body on cheaper pipework.
This flexible hose tap connector is used primarily when fitting or replacing kitchen and bathroom taps, connecting the 15mm supply pipe to the tap tail via a flexible, pressure-rated hose. It handles both hot and cold supplies and suits scenarios where the supply pipe and tap tail are slightly misaligned. Plumbers, bathroom fitters, and kitchen installers use these on almost every tap job as a matter of course, replacing rigid pipe connections that would otherwise require precise cutting and bending to achieve a leak-free fit.

Not suitable for: Not suitable for supplies operating above 70°C or pressures exceeding 15 bar. Not intended for gas connections or any application outside potable water and central heating systems.
Shut off the water supply at the nearest isolation valve or stopcock before fitting. Check that the supply pipe and tap tail are both clean and free from burrs or debris, as any rough edge can damage the olive and cause a slow weep at the compression joint.
Slide the compression nut and olive onto the 15mm supply pipe, insert the end of the hose connector, and tighten the nut finger-tight first. Repeat at the tap tail end. Use a spanner to tighten each nut by no more than one and a quarter turns beyond finger-tight. Do not route the hose with sharp kinks, and make sure there is no tension pulling at either end once the tap is in its final position.
Turn the supply back on slowly and check both compression joints for weeping. A dry joint straight away is a good sign, but check again after 24 hours, especially on a new fitting that has not settled under pressure yet.
Shut off the water supply at the isolation valve or nearest stopcock
Drain any residual water from the supply pipe before starting work
Check both ends of the flexible hose tap connector for damage before fitting
Slide the compression nut and olive onto the 15mm supply pipe
Insert the hose end into the compression fitting and tighten the nut finger-tight
Connect the opposite end to the tap tail in the same way
Use a spanner to tighten each compression nut approximately one and a quarter turns past finger-tight
Check that the hose is routed without sharp kinks and has no tension pulling at the joints
Restore the water supply slowly and inspect both compression fittings for leaks
Re-check both joints after 24 hours to confirm no weeping under sustained pressure
Is this tap connector hose suitable for both hot and cold supplies?
Yes. The EPDM core and stainless steel braid construction handles both hot and cold water supplies. The hose is rated to a maximum of 70°C, which covers standard domestic hot water supplies without any issue.
What does WRAS approved mean and does it matter for my job?
WRAS stands for Water Regulations Advisory Scheme. A WRAS approval means the product has been independently tested and confirmed as safe for use with drinking water in the UK. For most domestic and commercial plumbing work in England and Wales, using WRAS-approved fittings keeps you compliant with the Water Fittings Regulations 1999.
Can I use this connector with plastic pipework?
Yes, provided the plastic pipe is compatible with 15mm compression fittings. Many plastic pipe systems such as Speedfit or JG Speedfit use a plastic insert to support the pipe wall under the olive. Check the pipe manufacturer's guidance, but in most cases a standard 15mm compression fitting works fine with the appropriate pipe insert in place.
The hose body is constructed from EPDM rubber, a synthetic elastomer with good resistance to heat, ozone, and water over long service periods. The outer stainless steel braid reinforces the hose against pressure expansion and physical abrasion. Compression fittings at both ends conform to BS EN 1254-2, the British and European standard for copper and copper alloy fittings for water and gas. The fitting carries WRAS approval for use with potable water. Rated working pressure is 15 bar with a maximum operating temperature of 70°C.
