Product Overview
Swagelok SS-1RS4 Integral Needle Valve – Unused NOS
This is a Swagelok SS-1RS4 stainless steel integral needle valve with 1/4 inch connections, rated for 5000 PSI service in high-pressure fluid and gas control systems.
Integral needle valves like this one are designed to remove unnecessary joints and potential leak paths. It is a compact, disciplined piece of engineering that never entered service, reserved for systems that still value deliberate control at high pressure.
Product Condition
Unused, New Old Stock. The valve is not in the manufacturer’s original packaging and shows no signs of installation, modification, or operational use.
Product Overview
The SS-1RS4 is an integral needle valve intended for precise manual flow control in high-pressure instrumentation and process applications. Swagelok stainless steel valves are widely specified for their material consistency, machining accuracy, and long-term sealing reliability.

Frequently Asked Questions
Is this valve unused?
Yes. This valve is unused New Old Stock and was never installed or placed into service.
Does it include the original packaging?
No. The manufacturer’s packaging is not included, but the valve itself shows no signs of use.
What does “integral” mean in this context?
An integral valve incorporates the valve body and connections into a single unit, reducing potential leak points compared to multi-piece assemblies.
What pressure is this valve rated for?
The SS-1RS4 is rated for up to 5000 PSI, as specified.
Is this valve intended for on-off service?
No. As a needle valve, it is intended for precise flow control rather than simple shutoff.
Built for pressure, precision, and restraint, this SS-1RS4 is ready for systems where control is earned one turn at a time.
