Armstrong D553892 NO Cap Plug for 811 Inverted Bucket Steam Trap

Armstrong part D553892: no cap plug for the Armstrong 811 inverted bucket steam trap (800 Series).

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.
