Legend Valve 101-261nl Pex Tankless Service Valve Kit 3/4in

Product Description

The LEGEND VALVE 101-261nl is a lead-free tankless water heater service valve kit designed for 3/4-inch expansion PEX systems. Built from forged brass, this kit provides a reliable shutoff and service point on tankless water heater installations where code compliance and material longevity matter. It includes a pressure relief valve rated at 200,000 BTU/h and is engineered to handle demanding residential and light commercial plumbing environments. The FNPT union inlet paired with an expansion PEX outlet allows direct integration into NL F1960-series PEX piping without additional adapters. Licensed plumbers working on tankless heater retrofits or new rough-in installations will find the all-in-one kit format reduces fitting count at the heater connection.

This valve kit is intended for use on tankless water heater supply lines in residential and light commercial applications where 3/4-inch expansion PEX is the primary distribution piping. The FNPT union x Expansion PEX connection type suits installations following NL F1960 system standards. The integrated 200,000 BTU/h PRV is sized for common residential tankless units. The lead-free brass construction satisfies safe drinking water compliance requirements in jurisdictions that enforce lead-free plumbing material standards.

Shut off the cold water supply and depressurize the line before making any connections.
