SS 310 / 310S Instrumentation Tube Fittings Manufacturer, Supplier and Exporter in India
Arrotop is a manufacturer, supplier and exporter of SS 310 / 310S Instrumentation Tube Fittings for furnace instrumentation, kiln equipment, industrial heaters, heat exchangers, burner systems and other installations exposed to high operating temperatures.
The range includes SS 310 Compression Tube Fittings, SS 310S Single Ferrule Fittings and SS 310S Double Ferrule Tube Fittings for connecting instrument tubing with gauges, valves, manifolds, transmitters and process equipment. Standard fittings are available along with special reducers, adapters and drawing-based connections for OEM and project requirements.
SS 310 and SS 310S are mainly purchased for heat resistance rather than ordinary air, water or utility lines. Their higher chromium and nickel content gives them good resistance to oxidation and useful strength at elevated temperatures. SS 310S is widely used for furnace parts, radiant tubes, kiln equipment, heat exchangers and refinery equipment.
SS 310 / 310S Fittings for Furnace and Hot-Gas Instrument Lines
Instrument connections near furnaces, burners, ovens and heat-treatment equipment remain exposed to radiant heat, hot gases and repeated temperature changes. Ordinary stainless steel fittings may not be suitable for these conditions over long periods.
SS 310S Instrumentation Tube Fittings are mainly selected for furnace and thermal equipment where resistance to high-temperature oxidation is important. They are used for temperature monitoring lines, pressure instrument connections, burner control systems and sampling lines around hot process equipment.
SS 310S is identified as UNS S31008 / EN 1.4845. The fitting pressure and temperature rating depends on the fitting design, tube size, wall thickness, thread and complete installation. The maximum temperature of the raw material should not be treated as the automatic rating of the finished tube fitting.
Arrotop supplies high-temperature SS 310S tube fittings for new installations, plant maintenance, replacement requirements and complete project quantities.
Choosing Between SS 310 and SS 310S Tube Fittings
SS 310 and SS 310S belong to the same heat-resistant stainless steel family, but the required grade should be mentioned clearly in the purchase enquiry.
- SS 310 is generally identified as UNS S31000.
- SS 310S is identified as UNS S31008 / EN 1.4845.
- SS 310S has a lower carbon limit and is commonly specified for fabricated or welded high-temperature equipment.
- The required grade must match the project specification, tubing and material certificate.

SS 310 / 310S Instrumentation Tube Fittings are available in single ferrule and double ferrule designs for imperial and metric tubing. The required design depends on the tubing and the fitting system already used at the site.
SS 310S Fittings for Thermal Equipment and Process Plants
SS 310S fittings are mainly considered for instrumentation installed around high-temperature equipment. Typical requirements come from:
- Industrial furnaces and ovens
- Heat-treatment plants
- Rotary kilns
- Radiant tube systems
- Burner and combustion equipment
- Heat exchangers and recuperators
- Refinery heaters and hot process equipment
- Boiler and power-generation systems
- Petrochemical heating units
- Cement and mineral-processing plants
- Thermal test rigs
- OEM heating equipment
SS 310 / 310S is commonly used for furnace parts, radiant tubes, kilns, air heaters, heat-treatment equipment and refinery heating systems because it handles high-temperature oxidation well.
The actual service conditions still matter. A fitting installed near a furnace faces external heat, while another may carry hot gas or process fluid. Share the pressure, temperature and media details with Arrotop so the right fitting can be quoted.
Custom SS 310S Instrumentation Fittings for Thermal Equipment
High-temperature equipment often needs special connections that are not available as standard catalogue fittings. Arrotop manufactures custom SS 310S Instrumentation Tube Fittings from customer drawings, samples or required dimensions.
Custom requirements may include:
- Extended-body connectors
- Special furnace instrument adapters
- Metric-to-imperial connections
- NPT-to-BSP thread combinations
- Unequal reducing unions

- Customer-specific marking and heat-number identification
Replacement SS 310 / 310S Instrumentation Tube Fittings for Existing Equipment
Arrotop supplies replacement SS 310 / 310S tube fittings for furnaces, kilns, heaters and refinery equipment. Older systems may use special body sizes, thread combinations or ferrule designs that cannot be identified from the tube size alone.
For replacement matching, share:
- Clear photographs of the existing fitting
- Tube OD and wall thickness
- Male or female thread details
