This valve is compliant with UK plumbing standards for domestic use. If you specifically require a WRAS-approved valve for mains water supply applications, please see our KeyPlumb 15mm Full Bore Isolation Valve (WRAS Approved) or the WRAS Approved Butterfly Ball Valves. Can I order if the item shows as out of stock? Yes — we can fulfil this product even when stock shows as zero. Place your order as normal and we’ll confirm lead time with you. Does this work with plastic (push-fit) pipe? This valve uses a standard 15mm compression fitting. It is compatible with 15mm copper pipe. For use with plastic pipe, ensure you use the appropriate insert/liner within the compression fitting to prevent the olive from crushing the pipe. What is the difference between CxC and a flat-face compression valve? CxC (compression-to-compression) means both ends of the valve accept a standard olive-and-nut compression fitting — the most common type in UK domestic plumbing. A flat-face compression valve has a different end connection designed for specific fittings. For most standard installations, CxC is the correct choice. Why buy a pack of 10? The pack of 10 offers the best per-unit price and is ideal for trade use, full bathroom or kitchen fits, or keeping a stock of spares. At £1.50 per valve in the 10-pack versus £1.65 individually, the saving adds up quickly across a full job. Can this valve be used on a hot water supply? Yes — this valve is suitable for both hot and cold water systems in standard domestic plumbing applications.

A full bore valve maintains the same internal diameter as the connected pipework (15mm), so there is no restriction to flow when the valve is open. A standard bore valve has a reduced internal diameter which can restrict flow and cause a pressure drop. For applications where flow rate matters — showers, baths, washing machines — always choose full bore. Can I order if the item shows as out of stock? Yes — we can fulfil this product even when stock shows as zero. Place your order as normal and we’ll confirm lead time with you. How do I operate a screwdriver slot isolation valve? Use a standard flathead screwdriver. When the slot is parallel to the pipe, the valve is open. When the slot is perpendicular (across) the pipe, the valve is closed. It’s a quarter-turn (90°) operation. Is this valve suitable for heating systems? Yes — the 95°C maximum temperature rating makes this valve suitable for heating system pipework, including radiator isolation and boiler connections, within standard domestic operating temperatures. Does this work with plastic pipe as well as copper? This valve uses EN1254-2 compression fittings, compatible with 15mm copper pipe. For plastic pipe, use the appropriate insert/liner within the compression fitting to prevent the olive from crushing the pipe wall. Why buy a pack of 10? The pack of 10 offers the best per-unit price at £2.90 per valve versus £3.50 individually — a saving of 17% per valve. Ideal for trade use, full property fits, or keeping a stock of spares on the van.

A straight isolation valve is fitted inline on a water supply pipe to allow a single fixture — such as a basin tap, toilet cistern, or kitchen tap — to be isolated for maintenance or replacement without turning off the water supply to the whole property. It’s one of the most commonly fitted plumbing components in domestic installations. Can I order if the item shows as out of stock? Yes — we can fulfil this product even when stock shows as zero. Place your order as normal and we’ll confirm lead time with you. What is the difference between a straight and angled isolation valve? A straight (inline) valve is used where the pipe runs directly to the fixture — the valve sits in the pipe run without changing direction. An angled valve (90°) is used where the pipe comes up from the floor or out from the wall and needs to turn before connecting to the fixture. Choose based on your pipe configuration. How do I operate a screwdriver slot isolation valve? Use a standard flathead screwdriver. When the slot is parallel to the pipe, the valve is open. When the slot is perpendicular (across) the pipe, the valve is closed. It’s a quarter-turn (90°) operation — fast and positive. Does this work with plastic pipe as well as copper? This valve uses standard CxC compression fittings, compatible with 15mm copper pipe. For plastic pipe, use the appropriate insert/liner within the compression fitting to prevent the olive from crushing the pipe wall. Why buy the pack of 10? At £1.05 per valve versus £1.20 individually, the pack of 10 saves 12.5% per valve — ideal for trade use, full bathroom or kitchen fits, or keeping a stock of spares. The compare-at price reflects the full single-unit cost across 10 valves.

Not all isolation valves are the same — and this one is specified for a reason. The KeyPlumb 15mm Flat Face Compression x ½" BSP Isolation Valve is the correct valve for installations where a basin mono tap with a flexi tail connects to a 15mm copper supply pipe. The flat face compression end grips the pipe without an olive, while the ½" male BSP thread connects directly to the flexi tail. A flathead screwdriver closes it off in a quarter-turn. Chrome-plated brass, neat, and built to last behind a basin pedestal for years. Key Features Flat Face Compression Inlet — 15mm flat face compression fitting; connects to copper pipe without a traditional olive; provides a secure, leak-proof seal ½" BSP Male Thread Outlet — standard ½" male BSP thread; connects directly to flexi tails on basin mono taps, kitchen taps, and similar fixtures Screwdriver Slot Operation — quarter-turn flathead screwdriver; tamper-resistant and compact for tight under-basin spaces Chrome-Plated Brass Body — corrosion-resistant construction with a polished chrome finish; professional appearance for exposed installations Isolates Individual Fixtures — allows a tap or fixture to be isolated for maintenance without shutting off the water supply to the whole property Hot & Cold Water — suitable for both hot and cold water supply lines 1-Year Manufacturer’s Guarantee — backed by KeyPlumb warranty When to Use This Valve This valve is specifically designed for installations where: A basin mono tap (single lever, one tap hole) is being fitted with a flexi tail connection The supply pipe is 15mm copper and the tap tail is ½" BSP (the UK standard) A flat face compression fitting is required rather than a standard olive-and-nut compression If your installation uses a standard CxC compression connection (no BSP thread), see our Straight Chrome Isolation Valve or Full Bore Isolation Valve instead. Technical Specification Size 15mm Inlet Connection 15mm Flat Face Compression Outlet Connection ½" BSP Male Thread Operation Screwdriver Slot (quarter-turn) Body Material Chrome-Plated Brass Application Basin Mono Taps, Flexi Tail Connections, Hot & Cold Water Guarantee 1 Year SKU K23853 Alt. Part Numbers KPSTRFLA15 Brand KeyPlumb Complete Your Valve Range 15mm Straight Chrome Isolation Valve – CxC (WRAS) — standard CxC compression isolation valve; WRAS approved; for direct pipe-to-pipe isolation KeyPlumb 15mm Full Bore Isolation Valve – Chrome (WRAS) — full bore version for maximum flow; WRAS approved 15mm Chrome Lever Isolation Valve – Black Handle — CxC compression lever valve; no screwdriver needed 15mm Hot Water Butterfly Ball Valve – Red Handle (WRAS) — full bore butterfly valve for hot water lines 15mm Cold Water Butterfly Ball Valve – Blue Handle (WRAS) — full bore butterfly valve for cold water lines KeyPlumb 15mm Electrolytic Scale Reducer — inline scale reducer to protect valves and appliances from limescale Frequently Asked Questions What is a flat face compression fitting? A flat face compression fitting connects to the pipe using a flat sealing face rather than a traditional olive (ferrule). The pipe end is inserted and the nut is tightened, compressing the flat face against the pipe to create a watertight seal. It is commonly used in isolation valves where a BSP thread outlet is also required, such as this valve for basin mono tap installations. Can I order if the item shows as out of stock? Yes — we can fulfil this product even when stock shows as zero. Place your order as normal and we’ll confirm lead time with you. What is the difference between this valve and a standard CxC isolation valve? A standard CxC (compression-to-compression) isolation valve has compression fittings on both ends and is used to isolate a section of pipe. This valve has a flat face compression inlet on one end and a ½" BSP male thread on the other — making it specifically designed to connect a 15mm supply pipe directly to a flexi tail on a basin tap. If you don’t need a BSP thread outlet, use the straight CxC isolation valve instead. Will this fit my basin mono tap flexi tail? Yes — provided your flexi tail has a standard ½" BSP female connection (the UK standard for basin mono taps), this valve will connect directly. Check your tap’s flexi tail specification if unsure. Is this valve WRAS approved? This valve carries a 1-year manufacturer’s guarantee and is suitable for domestic hot and cold water supply. If you specifically require a WRAS-approved valve, please see our WRAS Approved Straight Isolation Valve or WRAS Approved Full Bore Isolation Valve. Can this be used on a hot water supply? Yes — this valve is suitable for both hot and cold water supply lines in standard domestic plumbing applications.
