It features a stainless steel bellows assembly and a 1\/2 in NPT lower process connection (04), housed in a phenolic case with a glass lens for clear visibility, and uses a 416 stainless steel movement. This dry instrument has an overall footprint of about 5-13\/16 inches long, 5-13\/16 inches wide, and 3-7\/16 inches deep, with a weight of approximately 2.50 lb (1.1 kg). The gauge is rated for low‑pressure ranges such as 0 to 60 inches of water (inH2O) and offers an accuracy of +\/- 2.5% of span (ASME B40.100 Grade A). Designed for compact installation in instrument panels, process lines, and HVAC or refrigeration ancillary systems, it provides a rugged, readily readable indication in tight spaces. The part number suffixes reflect stainless construction and the 1\/2 in NPT lower connection (04L), ensuring compatibility with standard piping and manifold configurations common in industrial and laboratory settings.\u003c\/p\u003e\u003c\/div\u003e","brand":"ASHCROFT","offers":[{"title":"New","offer_id":51660284789038,"sku":null,"price":248.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_be53d194-74e1-4b6f-aead-df7a91133a3b.jpg?v=1769535593","url":"https:\/\/plgautomation.com\/products\/ashcroft-45-1188-ss-04l-20iw-gauge-4-1-2-inch-dial","provider":"PLG Automation ","version":"1.0","type":"link"}
