Brass

Brass fittings and pipe nipples support commercial plumbing, maintenance, and OEM piping assemblies using compatible NPT-threaded components. This category includes fittings for closing pipe openings, joining or separating pipe sections, changing direction, creating branches, reducing connection sizes, and adding defined-length extensions in specified water, oil, gas, and steam applications.

Use Cases

Match the fitting to the pipe task

Use plugs and caps to close compatible threaded openings. Select nipples to create a defined extension between female NPT components, elbows to change direction, tees to add a branch, and unions where a connection may need to be separated for service.

How to Choose

Confirm threads, size, and configuration

Verify whether the connection requires male or female NPT threads, then match the listed pipe size and fitting layout. Reducing fittings are intended to transition between the stated connection sizes, while standard tees and unions join compatible same-size components.

Applications

Consider the stated system media and pressure

Representative fittings are intended for specified low-pressure water, oil, gas, and steam service. Certain chrome-plated brass fittings list service up to 125 psi for steam and 200 psi for water, oil, and gas, while listed red brass nipples carry a 140 PSI rating.

Additional Info

Review material and application restrictions

Chrome-plated brass fittings provide corrosion resistance and an easy-to-clean finish. Seamless red brass nipples are lead-free, while certain chrome-plated brass products are restricted to nonpotable-water use. Check the individual product details and minimum order quantity before ordering.

140 PSIListed nipple rating

Representative lead-free red brass pipe nipples are rated at 140 PSI.

200 PSIWater, oil, and gas service

Specified chrome-plated brass fittings support water, oil, and gas service up to 200 psi.

125 PSISteam service

Specified chrome-plated brass fittings support steam service up to 125 psi.

5 to 25Minimum order quantities

Listed minimum order quantities range from 5 to 25 each, depending on the product.

Fitting Types

Build, route, branch, or close threaded pipe runs

The available product types address common threaded-piping tasks in commercial plumbing and maintenance work.

  • Pipe nipples connect compatible female NPT fittings and provide a specified extension length.
  • Elbows route a line through a 90-degree turn; a reducing elbow also changes between listed pipe sizes.
  • Tees create three-way connections, including reducing tee configurations with a smaller branch.
  • Unions join compatible pipe sections and allow separation for service work.
  • Plugs and caps close compatible female or male NPT threaded openings, respectively.
Connection and Sizing

Start with compatible NPT thread direction and dimensions

Male NPT nipples and plugs connect to compatible female NPT openings. Female NPT caps, tees, elbows, and unions are used with compatible threaded components. Review every listed dimension, as diameter and length determine the connection and extension provided.

  • Listed nipple sizes range from compact 3/8 in. x 6 in. options to 3 in. x 3 in. options.
  • A 3/4 in. x 1/2 in. reducing elbow changes direction while reducing the connection size.
  • A 2 in. x 2 in. x 3/4 in. reducing tee provides two 2 in. connections and a 3/4 in. branch.
  • Union examples include 1/4 in., 3/8 in., and 2 in. female NPT configurations.
Material, Ratings, and Ordering

Check the details that affect application fit

Material construction and stated service limits differ by product. Select only for the media, pressure, and restrictions identified on the individual fitting.

  • Chrome-plated brass products provide corrosion resistance and an easy-to-clean finish.
  • Seamless red brass nipples are identified as lead-free and rated at 140 PSI.
  • Specified chrome-plated brass fittings support steam service up to 125 psi and water, oil, and gas service up to 200 psi.
  • Some products have minimum order quantities of 5, 10, or 25 each.
FAQ

Common questions before buying

What brass fitting should I use to extend a threaded pipe connection?

Choose a pipe nipple with male NPT ends and the listed diameter and length needed to connect compatible female NPT fittings.

When is a union fitting useful?

A union joins compatible pipe sections while allowing the connection to be separated for service work.

What is the difference between a plug and a cap?

A listed male NPT plug closes a compatible female NPT opening, while a listed female NPT cap closes a compatible male NPT connection.

Are all brass fittings in this category for potable water?

No. Certain chrome-plated brass fittings are identified for nonpotable-water use only. Review the individual product restriction before specifying a fitting.
