Armstrong International C5323-7 Stainless Steel Steam Trap

Armstrong's 1811 stainless steel inverted-bucket steam trap, model C5323-7, is a 3/4" NPT-connected, 30 psi-rated device designed for horizontal steam lines and condensate removal in low‑pressure service. It relies on an inverted-bucket mechanism and uses a 5/32" orifice in this variant, delivering reliable condensate discharge while minimizing live steam loss in small to mid-size steam systems. The unit is manufactured entirely from stainless steel to resist corrosion and withstand boiler-room conditions, and Armstrong's 1811 family is noted for freeze-resistant, all‑stainless construction that supports outdoor or unheated installations where needed. This trap is part of the 1800-series stainless inverted-bucket traps and is intended for horizontal installation on steam lines, making it a common choice for condensate drainage on trunks, coil returns, and heat exchangers in heating and processing facilities.
