Toilet & Faucet Supply Lines

Toilet & Faucet Supply Lines connect sinks and toilets to your home’s water supply with reliable, leak-resistant performance. This collection includes braided stainless steel, reinforced polymer, and flexible PVC hoses in popular lengths (12, 16, 20, 24, 30, 36, 48, and 60 inches) and common connection sizes: 3/8 in. OD compression, 1/2 in. IPS, and 7/8 in. ballcock for toilets. Quality lines speed up installation, resist kinks, and tolerate high water pressure to help prevent leaks and bursts.

Choose materials for your project and environment: braided stainless offers high burst strength and abrasion resistance; reinforced polymer is lightweight and corrosion-proof; PVC is budget-friendly for low-demand applications. Look for lead-free, code-compliant connectors, EPDM or PEX inner cores, and certifications such as NSF/ANSI and UPC for potable water.

Matching fittings is easy. At the shutoff (angle stop or straight stop), most valves use 3/8 in. compression. Faucets typically accept 1/2 in. IPS or 3/8 in. compression, while toilets use a 7/8 in. ballcock nut at the tank. Options include compression, push-to-connect, and click-seal ends that provide a positive, drip-free connection.

Installation is DIY-friendly:
- Shut off the water and relieve pressure.
- Place a towel or pan, then loosen the old line with an adjustable wrench.
- Hand-tighten the new line, then snug an additional quarter turn.
- Do not use thread tape on compression fittings.
- Open the valve and check for leaks.

Pro tips: measure twice and add slack for a gentle arc; avoid sharp bends; replace aging lines every 5–10 years; inspect annually for rust, bulges, or moisture. For added protection, consider flood-safe auto-shutoff connectors.

This category supports bathroom remodels, kitchen faucet upgrades, and quick fixes. You’ll find durable, corrosion-resistant supply hoses, angle-stop compatible connectors, and kits that simplify water supply hookups for toilets and faucets throughout your home.
