Sold as a complete PCA kit, it replaces the pressure-change mechanism that governs condensate release and trap activation, helping restore proper cycling and reduce nuisance discharge. The part is listed as B1671-2 with an F\/813,213 designation, featuring a 3\/8‑inch orifice and a 30# rating, and is referenced in Armstrong service literature as part of the PCA family used with multiple IB steam trap models.\u003c\/p\u003e\u003c\/div\u003e","brand":"ARMSTRONG","offers":[{"title":"New","offer_id":46277110989034,"sku":null,"price":218.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-076.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/armstrong-pca-213-813-3-8-17-4-h900-pressure-change-assembly","provider":"GTG Hardware","version":"1.0","type":"link"}
