Overview Manuals Thread Selection System Review Assembly Checks Applications

Features:

  • Thread reduction: Connects the documented 1/2 in male side to a 1/4 in female branch.
  • ISO tapered identity: The R and RT thread designations prevent substitution by nominal size alone.
  • 316 stainless body: Material identity remains part of the process-system selection review.
SS-8-RBT-4RT is threaded instrumentation hardware rather than a tube fitting or pressure regulator.

Selection starts with the complete connection designation on both sides, not the visible diameter.

The surrounding piping design remains responsible for ratings, material compatibility, support and test method.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Male side: Confirm the receiving port accepts the documented 1/2 in ISO tapered thread.
  • Female side: Confirm the branch component uses the documented 1/4 in ISO tapered thread.
  • Standard boundary: Do not treat NPT and ISO tapered threads as interchangeable.
  • Orientation: Plan final position without using excessive tightening to force alignment.
  • Material match: Review 316 stainless steel against the medium and adjoining components.
  • Pressure basis: Use the lowest rated component in the assembled fluid path.
  • Temperature effect: Recheck allowable pressure when service temperature changes.
  • Cleaning scope: Confirm SC-10 is suitable for the intended process cleanliness requirement.
  • Thread condition: Reject damaged or contaminated threads before engagement.
  • Alignment: Support adjoining piping so the reducer does not carry bending load.
  • Procedure: Apply the manufacturer method for the exact thread form and service.
  • Leak proof: Test the completed joint with an approved method before normal operation.
  • Instrument ports: Reduces an ISO tapered process connection for a smaller threaded device.
  • Analyzer panels: Adapts documented stainless threaded branches in compact layouts.
  • Utility manifolds: Provides a controlled size transition where both thread forms are confirmed.
  • Maintenance spares: Restores the exact Swagelok reducing-bushing identity in an existing assembly.
Description
A change from a larger male ISO tapered thread to a smaller female ISO tapered thread is the specific connection task of SS-8-RBT-4RT, making the reducer a directional size transition rather than a generic same-size coupling.

The 316 stainless body, SC-10 cleaning and no-flow-restrictor catalog configuration define how SS-8-RBT-4RT enters an engineered fluid path. Those order details help procurement preserve the exact material and cleanliness identity of an installed connection.

System suitability for SS-8-RBT-4RT still depends on the mating thread standards and the service conditions of the complete assembly. Treating nominal inch size alone as compatibility would erase the feature that distinguishes this reducer from nearby NPT or differently ended parts.

Technical notes
Identify both mating thread standards before installing SS-8-RBT-4RT; nominal inch size alone is insufficient. Confirm system material, pressure, temperature and process-fluid compatibility, then follow the applicable Swagelok assembly instructions. Avoid using the bushing to correct forced alignment, and inspect the completed joint under the site-approved leak-test method.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can SS-8-RBT-4RT enter a 1/2 in NPT port because the nominal size matches?
No. Confirm the receiving port uses the documented 1/2 in ISO tapered thread; nominal size alone does not establish compatibility.
The SS-8-RBT-4RT branch points the wrong way at normal engagement. Should it be tightened further?
Do not force orientation. Review the piping layout and the applicable tapered-thread assembly method before proceeding.
A process medium changes while SS-8-RBT-4RT remains installed. What must engineering reassess?
Reassess 316 stainless compatibility, operating temperature, pressure and every adjoining sealing or wetted component.
A sample line now needs a defined restriction at the SS-8-RBT-4RT location. Can this bushing provide it?
No. This exact bushing is listed without a flow restrictor; specify restriction as a separate engineered component.
Only the two nominal sizes are known during an SS-8-RBT-4RT outage. Is that enough to issue the spare?
No. Confirm both ISO tapered thread roles, 316 stainless material and the applicable pressure-temperature service before issue.
An SS-8-RBT-4RT joint seeps during proof testing. What comes before retightening?
Depressurize under site procedure, then inspect thread identity, condition, alignment and the recorded assembly method.
