Ganpat Metal Pvt. Ltd. supplies SS 316L tube fittings for industrial instrumentation, process tubing and equipment connections. Available requirements include tube-to-union, tube-to-male and tube-to-female configurations, compression fittings, adapters and other specified connection types, subject to product availability.
SS 316L is a low-carbon austenitic stainless steel grade used in tubing systems where material compatibility and the specified carbon limit are important. Selecting the correct fitting involves matching the material grade, tube outside diameter, thread type, end connection and operating conditions.
SS 316L tube fittings connect tubing to instruments, valves, equipment and other sections of
a process system. Their configuration depends on the required connection, tubing dimensions
and installation design.
The low-carbon composition of SS 316L distinguishes it
from standard SS 316. This grade is commonly specified for fabricated equipment and tubing
systems where welding may be involved, although suitability depends on the application,
fabrication procedure and service conditions.
Ganpat Metal handles enquiries
against defined material specifications, drawings, part numbers and purchase schedules to
help identify the required fitting configuration.
Final dimensions, thread types, pressure ratings, available configurations and documentation must be confirmed for the specific fitting and purchase order.

SS 316L tube fittings are selected according to the tubing arrangement and the interface required by the connected component.
The fitting design, connection mechanism and dimensions should be confirmed before ordering, particularly when replacing an existing component or matching a particular instrument connection.
The reference size range for SS 316L tube fittings is 1/16 inch to 2 inches in imperial dimensions and 2 mm to 50 mm in metric dimensions. Actual availability depends on the fitting type and product range.
Thread and end-connection compatibility is essential when specifying a fitting. Common options include:
NPT, BSPT and BSPP threads have different thread forms or sealing arrangements. They should not be assumed to be directly interchangeable. SAE, MS and AN connections also require confirmation of the applicable interface and dimensions.
For a quotation, specify the tube outside diameter, thread type, nominal thread size, fitting configuration and connection details. Drawings or existing part numbers can help identify the intended connection.
The supplied reference includes working-pressure values of up to 2,000–6,000 psi, as well as a separate reference of 1,200 psi or 8 MPa. These figures describe conflicting or potentially different rating conditions and should not be combined into one universal pressure rating for SS 316L tube fittings.
The permitted working pressure depends on factors such as:
The reference temperature range is -40°C to 250°C (-40°F to 482°F), but it should be published as a product-specific rating only after confirmation from the relevant manufacturer documentation. Pressure and temperature limits must be evaluated together for the intended application.
For an accurate quotation, provide the operating pressure, temperature, tubing specification, fitting size, connection type and process medium.
SS 316L tube fittings may be specified for industrial tubing assemblies where the grade and fitting configuration are suitable for the service conditions.
Final suitability depends on the process medium, concentration, temperature, pressure and connection design. Material selection should follow the applicable engineering specification.
Inspection and documentation requirements should be agreed at the enquiry stage and matched to the product standard and purchase order. Depending on the order, the documentation package may include:
Not every inspection or test applies to every fitting design. Confirm the applicable tests, certificate availability and inspection level before placing the order.
