Custom Machined Fittings – in Aluminum!

Large diameter aluminum fittings, for use with aluminum pipe sizes over 8″ in diameter, can be difficult to find. We have figured out a couple of help you to get what you need, in the quantity you need it in!

10″ x 6″ Concentric Reducer, Sch 40, 6061-T6, Machined Aluminum Forging – approximately 16 lbs. Made in Canada from Domestic Aluminum.

This 10″ x 6″ Concentric Reducer was manufacturer in Canada from forged aluminum – typically, only aluminum flanges cut from forged 6061-T6 but we also have eccentric reducers, caps and socket weld couplings cut from this very versatile alloy. These reducers are stamped with traceable heat numbers – just like flanges! They weigh in at about 16 lbs a piece which is almost double the American made concentric reducers (at 8.6 lbs each) – those are made from seamless 6061-T6. Different processes, different weights… The heavier Canadian reducers have a thicker wall through the body. If doubling the weight is not a concern, you have a choice! If the weight is a concern, we have an American manufacturer of concentric (and eccentric) reducers that we can call on for you.

6″ Stub End, Sch 40, 6061-T6. Made in the USA from Domestic Aluminum.

Custom ordered items such as stub ends can often be imported from the USA. Made from domestic aluminum, fittings such as stub ends are often ready to be shipped from American manufacturers and be available for your crew to begin welding within about 8 to 10 days. If we need to get these made for you it could take a bit longer.

So, choices…. We specialize in finding the aluminum (and other alloy) products that you need to do your job right! Send us a note or an rfq and we will get to work finding the right products for your next project!

Aluminum Couplers x 3 Wall Thicknesses

Did you know that aluminum couplers are available with three wall thicknesses?

  • Standard, NPT
  • 1-1/2 x Standard, NPT
  • 2 x Standard, NPT

also available in:

  • Socket Weld
  • NPT x Socket Weld
  • Reducing

All three wall thicknesses have internal threads with a 150# rating. All three are cut from 6061-T6 Seamless Aluminum. And, all three have great weldability. But, which one to choose?

Standard Wall Couplers are commonly used in small tanks. Consider these fittings for low pressure rated tanks (pressures under 150 psi).

2 x Standard Wall Couplers are known by several names. 3000# couplers, Sch 80 couplers, extra heavy couplers… The 3000# is a misnomer. Aluminum threads, cut into 6061-T6 fittings are good for working pressures of up to 150 psi. To make these extra-heavy wall couplers capable of standing up to higher pressures the coupler must first be welded and then the weld can be tested to the higher pressure rating. Sch 80 pipe can be used with all three wall thicknesses – they are all cut to accommodate the outside diameter of standard schedule pipe sizes.

1-1/2 x Standard Wall Couplers are not only in an in-between size, they are economical! When you need a fitting that is heavier than Standard but you don’t need the full 2 x Wall…. This is the one to choose. The wall is thick enough that you can weld them in and have them tested to a higher pressure rating than the Standard wall and you don’t have the bulk of the 2 x Wall. These couplers are also excellent for use as thru-hulls fittings.

… and, if you need something that doesn’t have thread or that reduces, we can usually get that for you! We specialize in getting the custom cut fittings that you need for your jobs.

Adding a Few More of those Difficult to Find Fittings – into Inventory!

Most of the time, Aluminum Fittings are fairly easy to find – if you are looking for elbows or couplers…  Then there are those pieces that are just much more difficult to find.  We are not only finding them, we are stocking (some) of them and we will get you accurate lead times on the rest.


Street Elbows – Cast Aluminum (356-F), Short Radius, Male x Female, NPT, 90 degree & 45 degree – Available in pipe sizes from 1/8″ to 6″ – If we do not  have the size you need, we can most likely bring it in for you.



Reducing Tees – Cast Aluminum (356-F), Short Radius, NPT – Available in pipe sizes from 1/2″ to 6″.  Reducing Elbows – Cast Aluminum (356-F), Short Radius, 90 degree, NPT – Available in Pipe Sizes from 1/2″ to 4″

Reducing Fittings reduce the need for extra fittings and connections.  Saving time (and thereby expense) in both initial use and maintenance.

Not a lot of stock on the Reducing Fittings, yet…  If we do not have the size you need, we can likely bring it in for you.  Please send an email ( or give us a call (778-288-6921) for P&D on these and other fittings.

If you need just a small amount 2, 5, 13-1/2 feet….  or, some similarly difficult to find short length, we may have what you need.

1/4″ Sch 40, 6061-T6

Small diameter aluminum pipe can be thought of as a casualty of hard times.  When new builds are not on the books and even maintenance is being put off, for the time…  small diameter aluminum pipe, and other extrusions, can disappear from the workplace and even from the mills.

Why?  Weight.

A mill order is generally calculated by weight.  This is easy when the pipe is a significant size: 2″ or 3″ pipe is easy to find, hence, a relatively realistic purchasing weight is available for those wanting to place mill orders.

This realistic weight is usually in the 1,000 lb. range.  When we start talking about the smaller diameter pipe though, the mill order quantity does not go down.  It remains at 1,000 lbs.  This means that 300 to 400 lengths of 1/4″ pipe have to be ordered.  That is a lot of linear feet!  When sales are slow, this is not a realistic number and, this is why the big suppliers of pipe are not always willing to carry the smaller diameters.  Depending on the market, it can take too long to sell the mill quantity or, translated, the accountants are often unhappy with mill order quantity purchases of small diameter pipe.


Our first Mill Order of 1/4″, Sch 40, 6061-T6 pipe (we did not ask our accountant about this!) is due to arrive the week of December 11, 2017.

We are accepting requests for quotes and pre-orders for both the Pipe and Pipe Nipples (NPT).
