Four common uses for bulkhead fittings


Bulkhead fittings are extremely useful not only for what they are actually intended for, but for many other, more improvised ways as well. The most common use is for attaching things like pipes, taps and outflows, and the like, or even waste pipes – but people have found many uses for them over the years outside of the usual intended use.

Here are some ways they’re used and how they can help. Let’s jump right in!

Aquariums

People use bulkheads in aquariums by drilling holes into the base of the tank- allowing them to drain water more seamlessly. If you’ve ever seen some of those deluxe aquariums in hotels or storefronts, they’re usually outfitted with bulkheads to make maintenance both easier and faster.

Ponds 

Coy ponds are a popular fixture in today’s garden and are almost always outfitted with some sort of bulkhead. This allows for easy drainage that allows for whomever is maintaining the pond to add in cleaner water easier and more often. Coy fish need clean water to survive and this makes the process of providing them with that even easier.

Large liquid containers and its transportation

Anytime you see a big barrel, chances are they are being outfitted with bulkheads. Not only does it make it easier to empty liquid – but it makes it easier to seal containers as well. In addition, many of the trucks that transport these materials also have them installed, as it makes things easier in the event of an accident or spill to rid the vehicle itself of any potentially hazardous materials.

Hydronic systems

Any sort of water heater you have uses bulkhead fittings to seamlessly circulate water through pipes, into holding tanks and into heating areas. In these particular applications, they come in a variety of materials ranging from PVC to brass, metal and other materials. When it comes to heating pipes, you’ll most likely encounter brass fittings.

The type of bulkhead fitting you come across or need will largely be dependent on how the bulkhead fitting will be used. To learn more – or if you need one for your application, give us a call and we can help find a solution for you.

 

Installing bulkheads on your own


In their simplest form – bulkheads allow air and liquids to pass through the wall of a tank or aquarium. Where and how the fluids get there can change a bit from time to time, but that’s the general gist.

Usually when it comes to our products, we recommend that you get a professional to help install them – but inevitably we always come across some eager, ambitious and capable Do-it-yourselfers who want to give things a go on their own.

Here are some things you need to do and know if you’re planning on installing bulkheads on your own.

 

Make sure your bulkheads are clean

Make sure that you install your bulkheads cleanly and in dry conditions. That includes not using silicone or some sort of threading lubricant. Specifically with regards to silicone and lubricants – they can cause the gasket to slip out and not seal properly. Any installation should be completely dry.

 

Finding other sources of leaks

Take a few minutes using a file, nail file or a pocket knife to do some cleanup on the threading. Clean off any excess flashing – and be sure to do it on both the male and female threads. Be sure to cover the entire component, too – from the gasket-mating surface to the flange and the nut. This is a common source of leaks in bulkheads.

You absolutely MUST…

…Install the gasket on the flange side of the bulkhead – never on the nut side. If you install the gasket next to the nut it will lead to leaks as water will simply travel along the threads around the gasket and leak out of your tank. Don’t be afraid to hand tighten a little bit – but don’t go with more than a ¼ or ½ turn additional.

Be wary of using supports and external elements

Generally speaking, it’s a bad idea to support pumps and piping from a bulkhead. Instead – use the supports in a way so that weight is not on bulkheads and gaskets and causing undue stress on the mating surfaces.

Also – never screw anything into the external threads of a bulkhead. They are not standard threads and they will leak.

Bulkhead Fittings Used in Manufacturing


If you are manufacturing tanks, including aquariums, you may be using one or more bulkhead fittings. As you know, these allow air or liquids to pass through the wall of a tank.

Bulkhead fittings have many applications in the construction and use of various types of tanks. They come is these sizes:

  • 3/4 inch
  • 1 inch
  • 1 1/2 inch
  • 2 inch

At JT Enterprises, we manufacture bulkhead fittings and sell them wholesale to manufacturers and retailers. If you’re looking to buy just one, or a few bulkhead fittings, we are not the place to go.

Bulkhead Fittings – ABS versus PVC


There are two kinds of bulkhead fittings; PVC and ABS. PVC is short for “Poly Vinyl Chloride” and ABS is short for “Acrylonitrile Butadiene Styrene”. Here are some of the differences;

  1. ABS plumbing is easier to install than PVC
  2. PVC is flexible; ABS is tough
  3. ABS has a higher impact strength than PVC
  4. ABS is cheaper than PVC
  5. PVC contains Bisphenol A (BPA) – ABS does not

In 2008, BPA made some news you may recall. Where the Food and Drug Administration had considered BPA safe before, but by 2010 it expressed concern about possible effects it may have on the health of children. See more here – Web MD.

Here at JT Enterprises, our bulkhead fittings are all ABS type and  contain zero BPA.

What are Bulkhead Fittings?


Bulkhead fittings are designed to allow liquids to flow through solid walls of a tank or other container. The fitting is made with three basic parts; the body, a lock nut, and a gasket.

The Body of the bulkhead fitting is threaded to fit the lock nut and has one end flanged out larger than the threaded part. The gasket goes between the body and the lock nut, to seal the fitting and prevent liquid from leaking.

To use a bulkhead fitting, one needs to drill a hole slightly larger than the outside diameter of the threads on the body part. The body with its gasket is placed through the wall of the tank or container, and the lock nut is tightened to seal the opening.

With a bulkhead fitting in place, you may now have liquids flowing in or out of the container in a convenient manner and without leaks.

Bulkhead Fittings for Aquariums

One of the main uses for bulkhead fittings is in aquariums. When you need to have a tube pass through the wall of an aquarium, a bulkhead fitting is needed to seal the tank and prevent leakage. For those who need only one or a few such fittings, there are many places to buy them online.

For companies that sell bulkhead fittings, or use them in the construction of aquariums, JT Enterprises in Holiday, Florida, has the best deal for buying them in larger quantities. JT Enterprises actually manufactures these parts locally and sells only to the wholesale market.

Questions from readers: Shipping


Questions from readers. My business is in Europe,  can we still buy from you?

Yes you can, however it is going to be more complicated.  Due to past bad experiences with fraud, we only accept wire transfers transactions for business. We can’t accept credit cards or PayPal.

You must also have your own freight forwarder or pick up. We will ship to a freight forwarder as long as it is in the continental United States. After we ship to the forwarder, we cease any responsibility for the shipment.
