Parallel Threaded Fittings from OmegaOne

OmegaOne manufactures stainless steel hydraulic fittings and adapters in a variety of thread types. We offer two main categories of threads which both perform and seal differently; Straight or Parallel Threads and Taper Threads

What is a Parallel Thread?

A parallel thread fitting seals using a sealing surface other than the threads. OmegaOne manufactures fittings which utilize three different parallel thread types, all of which are specified in the SAE J514 standard; SAW Flare and Flareless Fittings and SAE Straight Thread or O-Ring Boss (ORB).

SAE Flare or the OmegaFlare and SAE Flareless or the OmegaBite. The connection is made when a ferrule and nut all used to connect the fitting body with a flared tube.

SAE Straight Thread or O-Ring Boss (ORB) AN Standard Parallel Thread Fittings.

Though not as common anymore, you may come across a parallel thread fitting with reference to the AN standard. This standard was created during World War II to standardize the manufacturing of fittings used on military equipment. Now, this standard is similar to the SAE standard. SAE J514 fittings are dimensionally identical to AN fittings. 

O-Ring Face Seal OmegaSeal

Face Seal fittings also utilize a parallel thread. Similarly, to the flare and flareless fittings, face seal fittings also function with nut, sleeve and fitting body.

British Parallel Port (BSPP)

BSPP is predominant in Europe. As global manufacturing has expanded, there is more and more equipment found in the US that is manufactured in Europe and in use in the US.  OmegaOne does not stock fittings with BSPP; however, we are capable of producing this thread type and have produced this thread type.

Tapered Threaded Fittings from OmegaOne

OmegaOne manufactures stainless steel hydraulic fittings and adapters in a variety of thread types. We offer two main categories of threads which both perform and seal differently; Staight or Parallel Threads and Taper Threads.

What is a Taper Thread?

A tapered threaded pipe is commonly used in systems that handle liquids, gasses, steam, and hydraulic fluids. OmegaOne fittings and adapters are manufactured primarily for use in hydraulic systems. 

Tapered threads are used with: OmegaFlare, OmegaBite and OmegaSeal.

National Pipe Taper Thread (NPT) for Pipe Fittings

The most common fitting in the United States and Canada is the National Pipe Taper thread or NPT, also known as OmegaPipe. However, a taper thread is a mechanical seal that forms a dry seal. Because of this, taper threads are designed to work in conjunction with a lubricant to help prevent thread galling.

National Pipe Taper Fuel (NPTF) Standard

The National Pipe Taper Fuel(NPTF)standard is designed to provide a better seal than the NPT.  The NPTF thread is commonly referred to as a dry seal thread, which is designed to work optimally without the use of lubricants.

British Standard Pipe (BSP) or British Standard Pipe Thread (BSPT) Taper Threads

BSP and BSPT and essentially the same type of thread type, but the main difference is that BSP is not compatible with NPT while BSPT is. Though we do not stock BSP/BSPT as standard, we do produce specials and have limited stock of parts with BSP/BSPT threads.

At OmegaOne, our goal is to make fittings easy. That is why we are here to help you find the exact fittings and fitting thread you need to best suit your application.

Thread Galling and Stainless Steel Fittings

A common concern with any stainless-steel fitting is thread galling. When two surfaces come into contact with one another, there can be adhesion, which can cause the metal to tear on the thread. This is called thread galling, and it can cause damage to your fittings and decrease their longevity if not properly cared for. 

Which Fittings Can Experience Galling?

Thread galling in most common in tapered threads and NPT. The main issue with galling is that it leaves the fitting unsealed and can cause leaks. 

Fittings made with NPTF thread, are intentionally galled as part of its seal.

Thread galling will not occur with SAE, UNC straight threads, or BSPP (British Parallel Port, when assembled correctly.

In the OmegaOne products line, you can see thread galling in OmegaPipe, OmegaFlare, OmegaBite, and OmegaSeal.

How to Prevent Thread Galling?

Preventing thread galling is simple. Though straight thread fittings do not (generally) gall, thread galling can occur if the fitting is over-torqued.  Overtightening fittings involving a swivel nut can cause thread galling as well as compromise the 37° seat.  

When installing fitting using a swivel nut, proper alignment is critical to ensuring a correct seat and seal. Over tightening a swivel nut can cause damage to the seat and eventually gall threads if the threads are overworked.  Please reference the torque specifications per the SAE J514 standard for flare fittings.

With straight thread fittings that use an O-ring, it is advisable as long as the oil is compatible with the O-ring in use and the fluid in the system.

Introducing OmegaOne – Fittings Made Easy

OmegaOne is the name AMFM Incorporated conducts business under. AMFM was founded by Robert “Mac” McIntosh. Building off of a prosperous career in the metal hose industry Robert “Mac” McIntosh started AMFM Incorporated in the fall of 1987. AMFM pioneered the metal hose industry developing a product known as the braid band. Mac disrupted the metal hose industry by changing the braid band from an item metal hose fabricators made-up to an item they purchased. Purchasing this item allowed the time to prepare metal hose for welding to decrease dramatically improving efficiency and saving cost.

Mac designed, invented and built his own machines and tooling to manufacture AMFM Braid Bands. With his thorough understanding of the metal hose industry, Mac developed a sales and service process tailored to the needs of his customers. The values Mac instilled in AMFM remain the foundation of the company today.

Working diligently Mac persisted in his efforts until the AMFM Braid Band was adopted industry wide as the standard band for welding metal hose. Following Mac’s passing in 2002, Morgan R. McIntosh stepped forward becoming the company President from the role of Operations Manager.

AMFM continued growing through expansion into the fitting business. Both the acquisition of a machine shop in 2012 and Omega One, the stainless steel fitting company, in 2013 helped accelerate the steady growth of the company. Having successfully transitioned AMFM from its founder Morgan possessed the necessary experience to succeed Richard Profant the founder of OmegaOne.

Combined with AMFM Braid Bands the acquisition of OmegaOne added and a full line of stainless steel tube, pipe fittings and adapters. The acquisition re-shored the fitting product line which AMFM previously outsourced. In 2015 the company merged under the brand OmegaOne. The company developed a new logo and brand image to unify products and marketing.

All manufacturing is located in the Cleveland Ohio and the company proudly focuses on product Made in the USA.

Compare Benefits of Aluminum Pipe vs PVC

When it comes to piping, there is always one question that dwells on people’s minds. Should they go for aluminum or PVC pipes?

Contractors and engineers must be careful when choosing the best type of pipe for their compressed air system. The long-term effects of choosing either type of piping will outweigh any initial costs. This guide will identify the advantages and disadvantages of each, enabling you to choose the best type of pipe to use for your project.

High tolerance of heat

It is without a doubt that alloys have a high tolerance of heat. That is why they are ideal for those high-temperature environments in various industries.

PVC pipes would not work well as steam pipes or even hydraulic lines. It surely cannot be installed in areas where they might come into contact with fire or even hot water.

In fact, hot water that runs through PVC piping somehow tastes like plastic. On the other hand alloys, like aluminum alloys, are great heat conductors and they are heavily used in the plumbing, automobile, and robotic industries.

Light Weight

There is that notion that PVC pipes way a lot lighter than alloys. On the contrary, aluminum alloys are not really as heavy as some people think.

In fact, aluminum alloy is one of the lightest alloys out there. It is because of this that it is quite easy to install and even easy to repair. On the other hand, it can be quite intensive to repair PVC pipes.

Yes, aluminum alloys can be a little bit pricier than PVC pipes but more experts invest in the former since they would want something that can be repaired in a jiffy. Both options however, since lightweight, do not get shattered when dropped. And his brings us to another issue with is durability.


PVC pipes are praised for their flexibility. It is because of their flexibility that they are deemed durable.

When it really comes to toughness, it is without a doubt that aluminum alloys have a bigger advantage. Aluminum has been proven to have an excellent strength to weight ratio.

It is because of this that it is always the chosen material for whenever lightweight and durable pipes are required. On the other hand, PVC pipes, though flexible, can easily be crushed once they reach their breaking point.

Corrosive resistance

With PVC pipes, one does not need to worry about corrosion at all. That is why some people think that PVC pipes are the better option when it comes to hydraulics and compressed air systems. People do not want rust-polluted water or air.

However, one should not disregard the fact that aluminum has a very high level of corrosion-resistance – a level even higher than most metal alloys. The reason why aluminum is good at resisting rust is that it is covered with natural oxide.

Why You Should Choose Aluminum Pipe for Your Systems

In the long run, aluminum pipe can be the better cost-effective and versatile compressed air pipe system for your garage, shop, or warehouse.
