Worth flagging before anything else: roughly a third of the products currently filed under this brand are engineer's squares and measuring tools from SAM, Facom, Vogel, Starrett and RS PRO â unrelated companies that have nothing to do with Armstrong International, and almost certainly a data mis-tagging rather than a real product line. We've written this page around the genuine Armstrong International range and flagged the mismatch for a proper fix.
Armstrong International is a US steam specialties manufacturer (Three Rivers, Michigan), and the real range here is steam trap and condensate-return hardware:
- Inverted bucket steam traps â the 800-series and similar bucket traps, sized by pipe connection and pressure rating.
- Float & thermostatic (F&T) traps â for higher condensate loads, in cast iron and steel bodies across a range of pressure ratings.
- Steam chambers and humidification components â including scrubber/screen assemblies for steam distribution systems.
- Gaskets and seal kits â lid gaskets and tank seal kits for maintaining existing Armstrong equipment.
If you're maintaining a steam or condensate system, matching the trap type (bucket vs. F&T), connection size and pressure rating to the original is what matters â send us the model number stamped on the trap body and we'll confirm the equivalent.
We are not Armstrong International, and not an authorised Armstrong International distributor â genuine stock, sourced and supplied independently. Orders ship worldwide, and facilities and process-steam maintenance teams across the UK, Europe and the Middle East are regular buyers of this range.
Frequently Asked Questions
Why do some products under this brand look like measuring tools, not steam equipment?
That's a data-tagging issue on our end, not a real Armstrong International product line â those items belong to other manufacturers and we've flagged it to be corrected. This page describes the genuine Armstrong steam and condensate range.
What's the difference between an inverted bucket trap and an F&T trap?
An inverted bucket trap uses steam buoyancy to operate a valve and suits a wide range of pressures; a float & thermostatic (F&T) trap uses a float for continuous condensate discharge and handles higher loads â which one you need depends on your system, so send us the application or the old trap's model number.
Can you match a trap to a part number stamped on the old unit?
Usually, yes â send us the model or casting marks from the trap body and we'll confirm the equivalent or genuine replacement.
