Legend Valve 107-194NL 3/4 Inch Vacuum Breaker Brass

Product Description

The LEGEND VALVE 107-194NL is a 3/4-inch vacuum breaker designed to prevent backflow and back-siphonage at hose bibs and outdoor faucet connections. Also cataloged as the T-553NL, this fitting features a female garden hose thread inlet and a male garden hose thread outlet, making it a direct inline installation between a hose bib and an attached hose. The brass body construction provides corrosion resistance suitable for potable water and irrigation applications. This type of device is typically installed by licensed plumbers or experienced irrigation technicians where local codes require backflow protection at hose connection points.

The 107-194NL is suited for residential and light commercial applications where a hose connection poses a potential cross-connection risk to a potable water supply. Common installation scenarios include garden hose bibs, utility faucets, and irrigation supply connections. The female-in, male-out garden hose thread configuration allows the vacuum breaker to thread directly onto a hose bib, with the garden hose then threading onto the male outlet end.

Compatibility

Designed as an OEM-style replacement or new-installation vacuum breaker for standard 3/4-inch garden hose thread hose bibs and outdoor faucet connections.

Installation Notes

Installation is typically performed by a licensed plumber in compliance with local plumbing codes and IPC backflow prevention requirements. Shut off the water supply to the hose bib before servicing any upstream fittings. Thread the vacuum breaker onto the hose bib outlet by hand, then snug with pliers using a cloth or strap wrench to avoid marring the brass body. Do not over-tighten, as brass fittings can crack under excessive torque.
