The MCGUIRE 175SS20 is a flexible lavatory supply line designed for connecting shutoff valves to faucet inlets under residential and light commercial lavatories. The supply features a 1/2 inch copper sweat inlet and a 3/8 inch compression outlet, with a 20 inch braided stainless steel riser that provides corrosion resistance and flexible routing in tight under-sink spaces. Chrome plating on the fittings gives a finished appearance suited for exposed installations. This kit includes 2 risers per package. Licensed plumbers and experienced DIYers install this type of supply line during faucet replacement, sink installation, or routine supply line maintenance.
This supply line is appropriate for standard residential lavatory faucet connections where the shutoff valve has a 1/2 inch sweat connection and the faucet inlet accepts a 3/8 inch compression fitting. The 20 inch length accommodates typical under-sink cabinet depths and rough-in configurations commonly found in residential bathrooms. The braided stainless steel construction handles the minor movement and vibration that can occur during daily use, reducing the risk of pinhole leaks associated with corrugated chrome or PVC supply lines.
Designed as an OEM-style replacement supply line for residential lavatory faucet installations requiring a 1/2 inch sweat shutoff connection and a 3/8 inch compression faucet inlet.
This supply line is installed by licensed plumbers or qualified tradespeople. Shut off the water supply and relieve line pressure before disconnecting or installing any supply line. Do not overtighten compression fittings, as excess force can crack the nut or deform the ferrule and cause leaks. Check local plumbing codes, including IPC guidelines, for any requirements regarding supply line materials or connections in your jurisdiction.
