Ever-tite 3TPHA2575T Hydrant Adapter 2-1/2 Fnst X 3/4 Mnpt

Product Description

The EVER-TITE COUPLING PRODUCTS 3TPHA2575T is a brass hydrant adapter designed to connect a 2-1/2 inch Female National Standard Thread (FNST) inlet to a 3/4 inch Male National Pipe Thread (MNPT) outlet. This fitting bridges fire hose or hydrant connections to standard threaded pipe or hose systems, making it a practical component in water distribution, irrigation, and fire suppression support setups. At 0.91 pounds, the all-brass construction delivers corrosion resistance and reliable sealing under working pressures. Licensed plumbers, irrigation technicians, and fire protection contractors are the typical installers.

This adapter suits applications where a large-diameter hydrant port must be reduced to a standard 3/4 inch pipe thread connection. Common scenarios include connecting auxiliary water supplies from a fire hydrant or standpipe outlet to smaller-diameter hose bibs, pressure washers, irrigation mains, or test equipment. The threaded design allows hand-start engagement followed by wrench tightening for a leak-free seal without special tooling. It is appropriate for both residential and light commercial installations where the FNST-to-MNPT transition is required.

Key Features

• 2-1/2 inch FNST inlet accepts standard fire hose and hydrant port threads
• 3/4 inch MNPT outlet connects directly to standard pipe, valves, or hose fittings
• Full brass construction resists corrosion in wet and outdoor service environments
• Threaded connection type allows tool-assisted assembly without specialty equipment
• Compact and lightweight at 0.91 pounds for easy handling and storage

Compatibility

Designed as an OEM-style threaded adapter compatible with any system requiring a 2-1/2 inch FNST female inlet to 3/4 inch MNPT male outlet transition in brass construction.

Installation Notes

Installation is typically performed by a licensed plumber or fire protection technician. Shut off the water supply and relieve system pressure before making or breaking any threaded connection. Apply thread sealant tape or pipe dope rated for potable or non-potable water service as appropriate to the application. Tighten to snug plus wrench-tight; do not overtighten brass threads, as this can cause cracking at the fitting body.
