What this category is

The legacy fitting family that still keeps old air mains alive

PIPE FITTINGS
Threaded fittings repair traditional air mains

Steel and galvanized fittings are the elbows, tees, couplings, reducers, and nipples used on iron-pipe compressed-air runs.

MATCH EXISTING
Repair work follows the installed pipe

Thread type, size, material, and schedule matter more than preference when the customer is repairing an existing run.

UPGRADE PATH
New installs open the modular-piping conversation

If the job is a new main or large retrofit, compare threaded labor against modular aluminum before quoting only fittings.

The 2 types · side-by-side

Best-for, key trade-off, capacity, price band, and how deep the brand bench runs.

Distributor-facing reading. The trade-off column is the one that closes the loop — every type buys something and gives something up. Knowing what each type costs you is how the right one gets on the quote without a callback.

General threaded air-main repair Use for black-pipe compressed-air repairs where the installed system already uses threaded steel.
Labor-heavy on new installs Threading, sealing, and leak checking make it slower than modular piping on larger new runs.

3 questions “Funnel the Spec” to one product type.

Draw a line from the customer's answer at the top to the type name at the bottom. This is the page distributors screenshot and send to a customer the day before a quote call — so the customer comes prepared with the answers, and the call is about the brand and the budget, not the basics.

Question 1
Is the customer repairing an existing threaded air line?
Yes, black steel pipe
Recommend
Steel Fitting
Match the existing black-pipe system by size, thread, and fitting shape.
See product type →
Yes, galvanized pipe or corrosion concern
Recommend
Galvanized Fitting
Match material and thread while checking the corrosion context.
See product type →
No, new or major retrofit
Recommend
Modular Aluminum Piping
Compare installed labor, leak rate, and future changes before defaulting to threaded pipe.

The inputs behind the tree · what we'll need to quote

4 answers settle the right threaded pipe fitting — gather these before the quote call.

01
Is this a repair or a new installation?
Repairs usually match existing pipe; new installs may justify modular aluminum.
02
What size and thread standard is the pipe?
Threaded fittings must match size and thread form.
03
Is the existing system black steel or galvanized?
Material matching avoids corrosion and compatibility problems.
04
Is leakage or install labor the reason for the project?
That moves the conversation toward modular piping instead of more threaded fittings.
Where this category lives

Distribution & Conveyance is where leaks, pressure drop, corrosion, and repair speed show up. The right answer depends on whether the customer is building new, repairing legacy pipe, or upgrading to a cleaner modular system.
