Designed to be housed within the precision-machined grooves of API 6B or standard ASME\/ANSI B16.5 flanges, this metallic ring creates a highly secure, leak-proof metal-to-metal seal when the flange bolts are tightened. It is an absolute necessity for ensuring environmental safety and pressure containment in wellheads, pipeline manifolds, and heavy-duty valve assemblies.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eThe defining characteristic of this R-24 gasket is its \u003cb data-path-to-node=\"5\" data-index-in-node=\"55\"\u003eLow Carbon Steel\u003c\/b\u003e metallurgy. To create a perfect seal without causing irreversible damage to the expensive flange faces, the gasket material must be softer than the flange itself. This Low Carbon Steel gasket is strictly manufactured with a maximum hardness of 120 HB (Brinell). During installation, the softer gasket undergoes \"coining\"—a controlled plastic deformation—allowing it to flow into the microscopic imperfections of the flange groove, resulting in a bubble-tight barrier against high-pressure fluids and gases. To prevent rust and degradation during storage and prior to installation, the low carbon steel is typically treated with a protective zinc or cadmium anti-corrosive plating.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eAvailable in both standard oval and octagonal cross-sections, the R-24 gasket provides extreme reliability for non-corrosive (standard service) applications. Engineered in strict compliance with API 6A and ASME B16.20 specifications, this ring joint gasket ensures exact dimensional tolerances and unmatched sealing performance for critical infrastructure.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
