Located in the industrial hub of GIDC Makarpura, Apollo Steel Industries specializes in the manufacturing of high-precision Refractory Anchors, Wedge Anchors, and Hex Bolts.
Beyond manufacturing, we serve as a comprehensive partner for your piping needs, stocking a vast inventory of Stainless Steel, Duplex, Inconel, and Monel Pipes, Valves, and Fittings. Whether you need custom fabrication or bulk supply, we deliver certified quality.
Apollo Steel Industries is a trusted stockist and supplier of Double-Ferrule Compression Tube Fittings including Straight Unions, Male & Female Connectors, Elbows, Tees, Crosses, Bulkhead and Reducing Unions in Stainless Steel, Duplex, Monel, Inconel and Hastelloy. Every fitting is engineered to deliver a leak-tight, vibration-resistant seal without brazing or welding, supporting instrumentation panels and critical process tubing systems alike, with every consignment backed by complete mill test certificates and dimensional traceability.
Two-ferrule compression fittings that provide a metal-to-metal, vibration-resistant seal for joining two tube ends without brazing or welding, ideal for instrumentation and process tubing runs.
Connects tubing to male NPT, BSPT or BSPP ports, widely used to interface instrumentation tubing with valves, gauges and threaded process equipment connections.
Provides a tube-to-female-thread connection for linking instrumentation tubing directly to female-threaded ports on panels, manifolds and process instruments.
90-degree union, male and female elbow fittings that change the direction of a tubing run without additional bends, minimizing installation space in tight instrumentation panels and skids.
Three-way fittings used to branch or combine tubing lines, supplied in union, male-branch and male-run configurations for flexible instrumentation routing.
Four-way union fittings enabling multiple tubing branches from a single junction point, commonly used in manifold assemblies and multi-point sampling systems.
Designed for panel-through mounting, providing a leak-tight tube connection across enclosure walls and instrument panels while maintaining full pressure rating.
Connects two different tube sizes within the same run, allowing a smooth transition between varying tubing diameters without loss of joint integrity.
