Armstrong 811 1/2 in NPT Inverted Bucket Steam Trap

Armstrong's 800 Series inverted bucket steam traps are cast iron traps for horizontal installation with continuous air venting at steam temperature, a free-floating stainless steel mechanism and a discharge orifice at the top of the trap. They drain condensate from virtually every kind of steam-using equipment and stay efficient over long service, which lowers replacement and labor cost.
