Galvanized Threaded Pipe Fittings

Get Trust-Worthy Galvanized Pipe Fittings In Australia!

Air Energy provides a range of galvanized BSP tapered threaded fittings for very basic threaded fittings that are reliable and economic. We primarily promote stainless steel or brass fittings, but offer galvanised iron, or glass reinforced nylon as cheaper alternatives when required.

Polyethylene or polypropylene BSP fittings are not recommended for compressed air applications, and are really only suitable for water. With our vast selection of fittings, you will find something to match your needs.

If you are looking for threaded pipe fittings and are still determining what would be ideal for your system, you can rest assured. We are here to aid you with your queries and doubts so that you can get the best results. We at Air Energy guarantee the quality and provide you with a competitive price for our products.

Galvanized Pipe Fittings

Galvanised fittings are not dipped into molten zinc and then any threads are cut afterwards otherwise the molten zinc will block up the threads. Other zinc coatings can be applied by electroplating and may be colloquially referred to as galvanised, but the coating, although protecting threaded areas, is much thinner than actual galvanising. all zinc coatings are applied to steel to protect it from rust and corrosion. Making threaded pipes and pipe fittings out of galvanised steel rather than black or bright steel is is highly recommended since it gives resistance to rust and corrosion.

Galvanized steel fittings are offered in conventional diameters ranging from 1/4″ to 4″.

Advantages Of Galvanised Steel Pipes

Galvanized steel gains popularity from its ability to withstand corrosion and cheap cost, however pressfit stainless systems have largely replaced galvanised steel for pipework due to the much faster installation time, increased internal diameter and much better appearance and performance. Galvanized pipe fittings can endure the effects of weather for 50 to 70 years, making them long-lasting.

Disadvantages of Galvanized Pipe Fittings

Regardless of the number of advantages, the drawbacks of galvanized pipes are also to be considered when using the system.

Prone to internal corrosion

Steel pipes have a zinc coating on their outsides to prevent corrosion. Still, if even a little portion of that coating is removed, the pipe will begin to rust wholly and within corrode.

Water or Food Contamination

If the pipe develops rust or corrosion, the metal will react with the water and release toxic compounds that will form plaque inside the pipe and contaminate the water supply. GI Pipes are not food-grade materials. Thus the water from their water supply cannot be used for potable reasons.

Frequently Asked Questions

The most frequent application of compression fittings is on plastic pipes. We can supply compression fittings for high pressure stainless steel tubing, but the fittings and specialist tubing are expensive.
Tightening can be done initially by hand tightened with spanners or wrenches. To make sure the threads are correctly aligned, a good technique is to begin by rotating the fitting backwards to align the 2 threads by hand before using tools that may lead to cross-threading. Crossing threads not only makes it more difficult to subsequently align the threads but also increases the chance of stripping the threads.
All threaded joints require sealants to prevent leaks, but also to prevent spalling of stainless to stainless threads. Teflon tape is the most common. we only stock and recommend high body teflon tapes such as yellow for gas, green for Oxygen or grey for all general applications. A quality anaerobic sealant like Titaseal or one of the Loctite range is highly recommended.
It is often suggested to utilise a combination of Teflon tape and a silicone-based joint compound to achieve a thorough and dependable seal on threaded brass fittings. This approach provides an extra layer of assurance to ensure an utterly leak-free joint. Teflon tape acts as a reliable thread sealant, effectively preventing leaks by filling gaps between the threads. When paired with a silicone-based joint compound, the joint's integrity is further reinforced. It enhances the sealing properties and reduces the risk of any potential leaks. By employing this combination method correctly, you can achieve a secure and durable connection on your threaded brass fittings. Copper pipe fittings come in various types, each with different fitting methods to suit different plumbing needs. Here are the four main types of copper pipe fittings and their corresponding fitting methods:

  1. Type K : Type K copper pipe fittings can be joined using various methods, including soldering, compression fittings, push-fit fittings, press-connect fittings, and flare fittings (for flexible pipe applications).

  2. Type L: Type L copper pipe fittings can also be connected using soldering, compression fittings, push-fit fittings, press-connect fittings, and flare fittings (for flexible pipe applications).

  3. Type M : Type M copper pipe fittings can be joined using soldering, compression fittings, push-fit fittings, and press-connect fittings. Flare fittings are not typically used with Type M copper pipe.

  4. DWV (Drain, Waste, and Vent) : DWV copper pipe fittings are primarily used for drain, waste, and vent systems. They are typically joined using soldering or slip-joint methods, depending on the specific application and local building codes.
When selecting the appropriate copper pipe fitting type, it is essential to consider the specific plumbing requirements, local building codes, and the fitting method most suitable for the job. It ensures a secure and leak-free connection that meets the intended application's demands. You can consult with our plumbing professional to determine the most appropriate type of copper pipe fitting for a particular project.
Threading stainless steel pipe requires specialised dies rather than standard pipe dies. Standard dies are not suitable for threading stainless steel due to the material's hardness and unique properties. These special dies are specifically designed to handle the challenges presented by stainless steel, ensuring precise and clean threading.

When working with stainless steel pipes, it is essential to use the appropriate tools and equipment. It ensures efficient and effective threading, resulting in secure and reliable connections.
Poly fittings, also known as polyethylene fittings, do not typically require the use of thread tape. Poly fittings are designed with a tapered thread, which creates a tight seal without the need for additional sealing materials like thread tape. The tapered threads of poly fittings rely on compression and friction to create a secure connection, effectively preventing leaks.

However, it is important to note that the specific manufacturer's instructions and guidelines should always be followed when working with poly fittings. In some cases, thread tape or other sealing methods may be recommended or required for certain applications or unique circumstances. It is always advisable to consult the product documentation or contact the manufacturer directly to ensure the correct installation procedures are followed for poly fittings.
