SS 316 Instrumentation Tube Fittings Manufacturer, Supplier and Exporter in India
SS 316 Fittings for Chemical and Water Treatment Systems
SS 316 Instrumentation Tube Fittings are widely used in process lines exposed to moisture, salts and mild chemicals where ordinary SS 304 fittings may not be suitable.
They are commonly required for:
- Chemical dosing and injection panels
- Water treatment and filtration skids
- Sampling and analyser lines
- Cooling-water instrument connections
- Wastewater monitoring equipment
- Process control panels
- Pump and compressor instrument lines
- Valve and manifold tubing
- Equipment installed in humid or coastal areas
- Pharmaceutical and food-processing machinery handling compatible media
SS 316 is not automatically suitable for seawater, concentrated brine or every chemical. The grade should match the process specification and actual operating conditions.

Features of SS 316 Compression and Ferrule Fittings
- Manufactured from SS 316 / UNS S31600 / EN 1.4401 stainless steel.
- The molybdenum content gives SS 316 better resistance than SS 304 in many moisture, salt and mild chemical environments.
- Suitable for chemical dosing systems, water treatment equipment, analyser panels, cooling-water lines and process instrumentation.
- Available in single ferrule and double ferrule designs for different tubing systems and project requirements.
- In double ferrule fittings, the front ferrule forms the seal while the back ferrule grips the tube.
- Provides a secure tube connection when used with the correct tubing and installed properly.
- Suitable for process lines carrying compatible water, oils, gases and chemicals.
- A practical choice where SS 304 may not offer enough corrosion resistance, but Duplex, SMO 254 or a higher alloy is not required.

Arrotop supplies SS 316 connectors, elbows, tees, unions, reducers and adapters for new projects, plant maintenance and replacement requirements.
SS 316 Single Ferrule and Double Ferrule Fittings
SS 316 single ferrule fittings use one ferrule to grip and seal the tube. Double ferrule fittings use a front ferrule for sealing and a back ferrule for gripping.
The required design depends on the tubing, pressure, temperature and fitting system already used at the site. A double ferrule fitting should not automatically be treated as suitable for a higher pressure.
Arrotop supplies both designs in standard connectors, elbows, tees, unions, bulkhead fittings and adapters. Mention the ferrule type with your RFQ so the correct fitting can be quoted.
Custom SS 316 Instrumentation Fittings
Standard catalogue fittings may not match every analyser panel, skid or OEM assembly. Arrotop manufactures custom SS 316 Instrumentation Tube Fittings from drawings, samples or dimensional details.
Custom requirements may include:
- Metric-to-imperial adapters
- NPT-to-BSP thread combinations
- Special reducing connectors
- Extended-body fittings
- Custom bulkhead connectors
- Gauge and instrument adapters
- Reducer port connectors
- Special thread lengths
- Weld-end and socket-weld fittings
- Customer-specific body dimensions
- Special marking and heat-number identification
- Repeat components for OEM equipment
Send the drawing, tube size, thread details, material grade and quantity for review and quotation.
Replacement SS 316 Fittings for Existing Equipment
Arrotop supplies replacement SS 316 tube fittings for water treatment systems, chemical plants, process skids, analyser panels and industrial equipment.
Older installations may use special body dimensions, threads or ferrule designs that cannot be identified from the tube size alone. Share a clear product photograph, dimensions, tube OD, wall thickness, thread details and required quantity for replacement matching.
When a standard replacement is not available, Arrotop can manufacture the fitting from an existing drawing or physical sample.
SS 316 Tube Sizes, Threads and End Connections
SS 316 Instrumentation Tube Fittings are available for imperial and metric tubing in equal and reducing configurations.
Available connection options include:
- NPT male and female threads
- BSPT threads
- BSPP threads
- SAE and UNF threads
- Metric threads
- Tube × Tube connections
- Tube × Male Thread connections
- Tube × Female
- Thread connections
- Bulkhead connections
- Reducing connections
- Custom adapters for existing equipment
NPT, BSPT and BSPP are separate thread forms and should be ordered using the correct standard. Parker lists these as different thread and sealing arrangements across its fitting and adapter range.
Mention the tube OD, wall thickness, thread standard and size in your RFQ. Arrotop supplies standard and custom SS 316 NPT connectors, BSPT adapters, BSPP fittings and metric compression tube fittings.
Pressure Rating of SS 316 Tube Fittings
The working pressure depends on the fitting design, tube outside diameter, wall thickness, tube condition, operating temperature and end connection. Tube pressure tables also show different allowable pressures for different combinations of OD and wall thickness.
For product selection and pricing, send the tube size, wall thickness, operating pressure and temperature. This allows Arrotop to quote according to the actual requirement rather than using one general rating for every fitting.
Material Certification for SS 316 Fittings
Arrotop can provide the following documents when required:
- EN 10204 3.1 Material Test Certificate
- Raw-material certificate
- Heat-number traceability
- Dimensional inspection report
- PMI report
- Pressure or leakage test report
- Third-party inspection documents
- Certificate of origin
- Export documents
Share the required certificates and inspection details with your RFQ so they can be included in the quotation.
SS 316 vs SS 304 for Corrosive Instrument Lines
SS 304 works well for general industrial air, water and utility lines. SS 316 is usually selected when the instrumentation system faces moisture, salts, cleaning chemicals or mildly corrosive process fluids.
The molybdenum content in SS 316 gives it better corrosion resistance than SS 304 in many demanding environments. This makes SS 316 tube fittings for corrosive instrument lines a common requirement in chemical plants, water treatment systems, coastal equipment and process skids.
Arrotop supplies SS 316 male connectors, female connectors, elbows, tees, unions, bulkhead fittings and adapters for new installations and replacement requirements. Buyers can share the process media, fitting list, tube size and quantity for price and availability.
SS 316 Instrumentation Fittings for Analyser and Sampling Lines
Analyser and sampling systems need compact tube connections between the process line, valves, filters, regulators, sample cylinders and measuring instruments. SS 316 fittings are widely used for these assemblies when the system handles compatible liquids, gases or process chemicals.
Typical requirements include:
- SS 316 fittings for chemical sampling panels
- Compression fittings for process analyser lines
- Tube fittings for pH and conductivity instruments
- SS 316 connectors for water-quality monitoring panels
- Gas sampling system fittings
- Sample cylinder and grab-sampling connections
- Pressure regulator and filter connections
- Flowmeter and transmitter hook-ups
- Custom adapters for analyser skids
Grab-sampling systems are designed to collect representative liquid or gas samples from process lines, and tube fittings form part of the panel connections used in these systems.
Arrotop supplies connectors, elbows, tees, unions, reducers and custom SS 316 Instrumentation Fittings for analyser and sampling systems. Send the fitting schedule or panel drawing for quotation.
SS 316 Tube Fittings for Plant Shutdown and Maintenance Orders
Plant shutdown work often involves replacing leaking, damaged or corroded fittings within a fixed maintenance schedule. Arrotop supplies SS 316 Tube Fittings for plant shutdown and maintenance requirements, including small replacement quantities and complete fitting packages.
Maintenance orders may include:
- Male and female connectors
- Elbows, tees and unions
- Bulkhead fittings
- Front and back ferrules
- Reducer port connectors
- NPT, BSPT and BSPP adapters
- Metric and imperial fittings
- Custom replacements made from drawings or samples
Older installations may use special threads, body sizes or ferrule designs. Share a clear photograph, fitting dimensions, tube OD, thread details and required quantity for replacement matching.
For planned shutdown requirements, send the bill of materials and delivery schedule in advance. Arrotop can quote standard and custom SS 316 maintenance tube fittings with the required material certificates and export documents.
