Stainless steel braided supply lines are flexible hoses used to connect fixtures such as faucets, toilets and dishwashers to the home’s water supply. They offer a combination of strength, flexibility and corrosion resistance that makes them a reliable choice for modern plumbing.

Construction and materials

• Braided stainless outer sheath: A woven stainless steel wire jacket encases the hose, protecting it from abrasion and providing high burst strength.
• Reinforced inner tube: Inside the braid is a food‑grade vinyl or PEX tube reinforced with synthetic fibers. This inner hose carries the water and can handle pressures up to about 125 psi and temperatures between 40 °F and 150 °F.
• Lead‑free fittings: End fittings are typically made from brass or stainless steel and comply with low‑lead or lead‑free standards for potable water.

Advantages

• Flexibility: The braided sheath allows the hose to bend easily without kinking, making installation simpler in tight spaces.
• Durability: Stainless steel resists corrosion and damage, while the reinforced core withstands high pressure and temperature fluctuations.
• Versatility: Available in various lengths (from 12 inches up to several feet) and end fitting configurations (compression, FIP, MIP) to suit sinks, toilets, refrigerators and washing machines.
• Easy to replace: Unlike rigid piping, braided lines are easy to disconnect and replace during fixture upgrades or repairs.

Installation tips

• Measure the required length and select a hose that provides a gentle curve without excessive slack or stretching.
• Ensure the end fittings match the supply stop valve and fixture connections (e.g., 3/8 inch compression to 1/2 inch FIP).
• Hand‑tighten the nut onto the fixture or valve, then use a wrench to turn an additional quarter turn to seal. Do not over‑tighten, as this can damage the washer.
• After installation, flush water through the line to remove any debris. Check for leaks and tighten gently if necessary.
• Periodically inspect supply lines for signs of wear, corrosion or bulging and replace them at the first sign of deterioration.

Stainless steel braided supply lines provide a dependable connection between your plumbing fixtures and the water supply while offering flexibility and long service life.
