Query product →Where this configuration fits
Typical connection points include pumps, valves, cylinders and manifolds. A matching thread diameter alone does not establish a seal: parallel and tapered port designs require different mating arrangements.
Details to include in your enquiry
- State BSPP (G), BSPT (R), NPT, metric or UNF/UN for the equipment port.
- For a parallel thread, identify the specified O-ring, ED ring or sealing face.
- Measure tube outside diameter separately from thread diameter.
- Include port depth and wrench clearance when the connector fits a confined manifold.
Sizes, materials and supplied condition
Specify the tube outside diameter, LL/L/S series, material and every connection. The overall catalogue covers 4–42 mm tube, but an individual configuration may have a narrower range. Carbon steel, 316L and 316Ti can be included in an enquiry, subject to confirmation of the supplied item.
State whether you require complete fittings or bodies only. Include working pressure, peak pressure, temperature, medium and any certificate requirements so the complete assembly can be checked.
Select materials, seals and pressure capability →JIC and O-ring boss transitions
Additional transition options can be requested where the circuit uses JIC 37° or UNF/UN O-ring boss connections. JIC seals on a flare seat; an O-ring boss connection seals at its specified port. Similar threads do not make the sealing arrangements interchangeable.
Technical selection guides
DIN 2353 fitting sizes, series and thread identification
Identify a DIN 2353 connection by tube outside diameter, fitting series, thread and sealing form. A matching thread alone does not establish a correct connection.
Selecting materials, seals and pressure capability for DIN 2353 fittings
Select the fitting, tube and seals as one assembly. Pressure capability depends on the exact configuration, material, tube dimensions, temperature and installation method.
DIN 2353 fitting installation and inspection overview
Successful cutting-ring connections depend on suitable tubing, matched components, careful preparation and the correct assembly procedure for the supplied fitting system.
Questions answered
How do I specify tube-to-thread fittings?
Identify the configuration, tube diameter and series, all connection threads and seals, material, quantity and operating conditions. Send a marked sketch when port positions or different end sizes matter.
Are the catalogue dimensions suitable for final fabrication?
Use them to identify and enquire about the configuration. Obtain the order-specific drawing and confirmed pressure rating before fabrication or installation.
