The brass hydrants are generally used to assist firefighters in preparation and cut time. This is helpful in emergencies and is advantageous in other firefighting applications.

Can You Use Brass Connectors In Drinking Water Plumbing System?

Yes, zero lead Brass connectors are constructed with marine-grade DZR brass. The safe drinking water act cleared this type of brass.

Most brass connectors have lead and have been known to leak lead into the water supply. For this reason, brass connectors are mostly used for non-potable water uses.

It is recommended that pipes with brass connectors should not surpass a speed of three meters per second. Higher speeds coupled with rapid scouring could lead to an increased risk of erosion of interior passage of the piping system.

Because of the brass connector’s electrical conductivity, the grounding connections should be far removed from the pipes and any electrical wires.

Do You Measure Brass Connector Size By The Outer Diameter (OD) Or Inner Diameter (ID)?

Mostly, the brass connector size is measured by ID. The ID is an abbreviation that stands for inner diameter. You can measure the ID  using a set of calipers.

Which Are The Brass Connector Thread Types?

There are different types of brass connector threads. They include;

  • UN Threads; the unified threads have a sixty degrees profile. Their dimensions characteristics, the OD, and pitch were selected in fraction of inches as opposed to the usual values in millimeters.
  • UNF Threads; the Unified national fine threads are similar to the UN. However, the main difference being it that UNF has a more specified fit.

As a result, they have a tighter tolerance and finer adjustment. They have a better twisting force and are suitable for bulkier loads.

  • NPT Threads; the NPT threads have tapers; the brass connector mechanical lock engages when the male and the female tapers connect.
  • NPTF Thread; The NPTF has a similar structure to that of the NPT threads. The main difference is that the NPT may require a sealant to prevent leakage.

Whereas, the NPTF locks completely and does not require aid.

NPT Male Thread to NPT Female Thread Brass Reducer

NPT Male Thread to NPT Female Thread Brass Reducer

  • BSP Thread; The British standard pipe is a thread type that operates by coupling and locking pipes and connectors by joining the male and female thread.

There are two types of BSP threads and they are;

  1. BSPT Thread; is the British standard pipe that is tapered. The Female thread in this type of thread can either be parallel or tapered and the male thread is generally tapered.
  2. BSPP Thread; the British standard pipe that is parallel has straight threads that are parallel.
  • Metric Parallel; the metric parallel work by sealing using an O-ring. They usually are fixed into ports that are parallel.
  • Metric Tapered Thread; The metric threads work by locking using either small thread deformation or using wedging of two metals.

What Is The Difference Between MPT And NPT In Brass Connector?

The Male Pipe Thread ( MPT) and the Female  Pipe Thread (FPT) both fall under the National Pipes Thread. The National Pipe threads are tapered threads that are used to connect and lock pipe connectors.

How Does Tapered Thread Vs. Parallel Thread Of Brass Connector Compare?

The Parallel threads are threads with straight walls. Parallel threads mostly require sealants to prevent leakage and an O  ring to seal them properly.

The tapered threads have a reducing diameter the lower you go. This means that if you proceed along the length of the tapered threads the threads eventually come together.

The tapered threads join either by imperfections on the thread or wedging of two metals

Do You Require A Sealant When Installing A Threaded Brass Connector?

Yes,  a sealant may be required depending on the type of threaded brass connector you are using.

In plumbing, use of sealants is a common practice to prevent any leakage that may occur when using threaded brass connectors.

Most of the brass connectors are joined to pipes with compression fittings.

The compression fittings have two main parts; the interior compression ring and the outer compression ring.

One does not require a sealant when installing a threaded brass connector. However, that does not mean that you can’t use a sealant if you wish to.

What Is The Working Pressure Of Brass Connector?

The working pressure of brass varies according to the type of brass connector and the application.

There are however overall guides that help in setting a baseline for the brass connectors’ working pressure.

For extruded brass pipe connectors and the brass connector nipples, working pressure of up to three hundred psi can be applied.

Brass connectors generally can have a working pressure of up to 1000 psi can be applied at room temperature.
