Fire Hose & Hydrant Adapters

Fire hose and hydrant adapters provide threaded transitions between compatible hose, pipe, and water-system connections. Common commercial uses include fire-safety equipment maintenance, facility plumbing work, industrial hose-system setups, and joining fire hose components with different thread types, genders, or sizes.

Helpful Buying Guide

Choose a compatible fire hose or hydrant adapter

The products represented in this category include reducers, nipples, double-female adapters, a double-male nipple, and a replacement swivel gasket. Start by identifying the exact connection required on each side, including thread type, size, and gender. Then compare the fitting configuration, material, wrenching feature, and whether swivel positioning is needed.

Use Cases

Connect compatible hose and pipe components

Use adapters and nipples to transition between compatible NH, NPT, NPSH, GH, and GHT connections. Reducers address different connection sizes, while same-size adapters can join matching hose-threaded connections.

How to Choose

Match both ends before selecting

Verify the female or male orientation, nominal size, and thread designation at each connection point. For example, listed options include NH-to-NH reductions, NH-to-NPT transitions, NPT-to-NH connections, and NPSH-to-GH or NPSH-to-NH transitions.

Applications

Support maintenance and hose-system setups

These fittings are suited to fire-safety, facility maintenance, plumbing, industrial, and fire department applications where compatible threaded equipment must be joined or serviced.

Additional Information

Consider installation and service details

Listed wrenching features include rocker lugs, pin lugs, hex sections, and wrench flats. A double-female NH adapter has dual swivel ends, and a 2-inch swivel gasket is available as a replacement sealing component for compatible connections.

Planning Guide

Plan the right fit before choosing

1. Identify the connection at each end

Check thread type, size, and gender

A fitting must match the two compatible components it is intended to join. Review both ends of the required connection rather than selecting by nominal size alone.

  • NH connections are represented in 1 inch, 1-1/2 inch, 2-1/2 inch, and 3 inch sizes.
  • NPT, NPSH, GH, and GHT thread types are also represented.
  • Configurations include female-to-male, double-male, and double-female options.
2. Select the fitting configuration

Choose a reducer, nipple, or adapter for the transition

Reducer adapters join different sizes, such as 1-1/2 inch NH female to 1 inch NH male or 3 inch NH female to 1-1/2 inch NH male. Nipples provide threaded transitions, including NPT-to-NH and NPSH-to-GH arrangements. Double-female adapters join compatible female-threaded connection requirements.

  • Choose a reducer when the compatible connection sizes differ.
  • Choose a nipple for the listed threaded transition between components.
  • Choose a swivel adapter where connection positioning is needed.
3. Review material and handling features

Compare the listed body material and wrenching style

Available fitting materials include aluminum and brass. Aluminum reducer adapters are listed with rocker lugs, while several brass adapters and nipples include pin-lug or hex wrenching features. The replacement gasket is made from oil-resistant synthetic rubber.

  • Rocker lugs provide a wrenching surface on listed aluminum reducers.
  • Pin-lug features support wrench engagement on listed brass adapters.
  • Hex sections or wrench flats provide a defined grip for installation or removal.
