Corrugated Flexible Water Supply Hose with Brass Fittings — 1/2", 3/4", 1" | Hot & Cold

Measure the distance between your supply valve outlet and the fixture inlet, then add 2–3 inches of slack to allow for easy connection and minor misalignment. Available lengths run from 150mm (≈5.9") up to 1000mm (≈39.4"). When in doubt, size up — a slightly longer hose is far easier to work with than one that's too short and puts stress on the fittings.

Match the hose diameter to your existing supply valve or fixture inlet thread size. In most US residential plumbing: 1/2" is standard for faucets, toilets, and showerheads; 3/4" is typically used for washing machines, outdoor hose bibs, and some shower valves; 1" is generally for main supply lines or high-flow commercial-style fixtures. Check the thread size on your valve before ordering.

Yes — this corrugated flexible hose is designed for both hot and cold water supply lines. The stainless steel body and brass fittings are generally suitable for the temperature ranges found in standard residential hot water systems. For exact maximum temperature ratings, please contact us to confirm before use in high-temperature applications.

The stainless steel corrugated body offers good moisture and corrosion resistance, making it well-suited for damp indoor environments — under-sink cabinets, shower enclosures, utility rooms, and laundry areas. For fully exposed outdoor installations subject to UV, freezing, or direct weather, we recommend contacting us to confirm suitability for your specific conditions.

The brass end fittings are generally manufactured to BSP (British Standard Pipe) thread standards. BSP and NPT (National Pipe Thread, common in US plumbing) are not directly interchangeable. If your supply valves or fixtures use NPT threads, you may need a BSP-to-NPT adapter. Please contact us with your size before ordering and we can confirm thread compatibility.

The corrugated stainless steel construction is designed to handle typical residential water supply pressures. In most cases, these hoses are suitable for standard household systems (typically up to 10 bar / 145 psi, though this varies by size). For high-pressure or commercial applications, please contact us to confirm the rated working pressure for your chosen diameter and length.

No special tools are required. Generally, you'll need only an adjustable wrench or spanner to tighten the brass fittings — no soldering, crimping, or compression tools needed. Always wrap the male threads with PTFE (plumber's) tape before connecting to ensure a watertight seal. Hand-tighten first, then snug with a wrench — avoid over-tightening, which can damage the brass threads.

Yes — the 1/2" size is typically compatible with standard shower valve supply connections. The flexible corrugated body makes it easy to route the hose in tight wall cavities or around shower enclosure frames. Confirm your shower valve inlet thread size and type before ordering to ensure a proper fit.
