FIDISP 8Pcs 3/4-Inch IPS Isolator Tankless Water Heater Valve Kit – Brass, NPT to FNPT, Pressure Relief

Elevate maintenance and service for tankless water heaters with the FIDISP 8Pcs 3/4-Inch IPS Isolator Kit. Designed for fuss-free flushing and safe isolation, this kit combines durable brass components with intuitive color-coded handles, helping you identify hot and cold lines at a glance while supporting reliable operation over time.

The kit centers on two reducer adapters that connect 3/4-inch NPT to 1/2-inch FNPT, enabling compatibility across common tankless models and threaded connections. The lead-free brass construction delivers corrosion resistance and long-term durability, while CSA-grade approval adds an extra layer of assurance for robust performance in everyday use.

Compatibility spans popular manufacturers such as Rheem, Navien, Rinnai, Ecosmart, Noritz, Takagi, and other 3/4-inch system configurations, making this kit a versatile addition to service setups. Each valve handle is color-coded to quickly differentiate hot and cold lines during installation or maintenance, saving time and reducing confusion in tight spaces.

Included in the packaging are essential components that support a complete service workflow: one hot isolation valve, one cold isolation valve, one pressure relief valve, two brass pipe fittings (3/4" NPT to 3/4" NPT), two reducer bushings (3/4" NPT to 1/2" FNPT), and a roll of Teflon tape for sealing threads. This all-in-one kit helps simplify inventory and onsite readiness, so you can tackle flushing or servicing with fewer trips to the tool rack.

Note: Except for the hot and cold isolation valves and the pressure relief valve, the brass fittings are low-lead and designed for use with a variety of pipe types. They are not intended for potable water connection tools. With mindful handling, these fittings support flexible installation in many common residential and commercial setups.
