Fluidmaster prof620 Faucet Supply Connector 20 in 3/8 Comp

Product Description

The FLUIDMASTER prof620 is a braided stainless steel faucet water supply connector designed for residential and light commercial lavatory faucet installations. Built on a tough polymer core encased in braided stainless steel wire, it delivers high flow capacity through an ample inside diameter while resisting kinking and creasing even in confined under-sink spaces. The nickel plated brass end fittings accept a 3/8 inch compression connection on each end. At 20 inches in length, it suits most standard vanity cabinet depths. Licensed plumbers and skilled trade professionals install this connector as part of routine faucet replacement or new fixture rough-in work. The connector meets NSF 61 standards for drinking water system components and carries a 10 year warranty.

The prof620 is intended for faucet supply line applications in bathrooms and lavatories. Its exceptional flexibility allows routing around cabinet obstructions and tight bends without compromising flow or creating stress points in the line. The 3/8 inch compression fittings on both ends are among the most common connection types found on shutoff valves and faucet inlets in residential plumbing. This connector ships 25 units per case, making it practical for plumbing contractors and service companies stocking high-turn replacement parts.

Compatibility

Designed as an OEM-style replacement or new-installation supply connector for lavatory faucets with 3/8 inch compression inlet connections paired to 3/8 inch compression shutoff valves.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply at the angle stop valve and relieve pressure before disconnecting any existing supply line. Hand-tighten the compression fittings first, then snug with an appropriately sized open-end or basin wrench — avoid over-tightening, which can distort the compression seat. After installation, restore water supply slowly and inspect both ends for leaks before closing the cabinet.
