SS 304 Instrumentation Tube Fittings Manufacturer, Supplier & Exporter in India
Arrotop manufactures, supplies and exports SS 304 Instrumentation Tube Fittings for industrial tubing systems carrying air, water, gases, oils and other compatible process media. These fittings provide secure and dependable tube connections for instrumentation panels, utility lines, process equipment, testing systems and general industrial installations.
Our manufacturing range covers SS 304 Compression Tube Fittings, Single Ferrule Tube Fittings and Double Ferrule Tube Fittings in different tube sizes, thread combinations and end connections. Precision machining helps maintain accurate dimensions, proper ferrule action and a firm grip on the tube, reducing the risk of leakage during normal operation, pressure changes and equipment vibration.
Stainless Steel 304 Instrumentation Fittings
Stainless Steel 304, also identified as AISI 304, UNS S30400, DIN 1.4301 and SUS 304, is a widely used austenitic stainless steel grade. It offers a practical combination of corrosion resistance, mechanical strength, machinability and cost. This makes SS 304 Instrumentation Fittings a suitable choice for general industrial service where the system does not handle seawater, high chloride concentrations or highly aggressive chemicals.
For many air, water and utility applications, SS 304 provides a cost-effective alternative to higher-alloyed materials. Where the process involves strong chlorides, marine exposure or more corrosive chemicals, the operating conditions should be reviewed before selecting the material.
SS 304 Compression, Single Ferrule and Double Ferrule Fittings
Arrotop supplies SS 304 Compression Tube Fittings in single ferrule and double ferrule configurations. Single ferrule fittings offer a straightforward connection for general instrumentation work, while double ferrule fittings use separate front and back ferrules to provide additional tube grip and sealing support.
The right design depends on the tube material, outside diameter, wall thickness, pressure, temperature, process media and vibration level. Our team can review these details before quotation and recommend a suitable configuration for the required service.
