Reducing Coupling for Stainless Systems

This 316 stainless steel reducing coupling connects 1-1/2" and 3/4" FNPT threads in industrial piping. The SS316 body resists corrosion in chemical and marine environments where standard grades fail. It suits maintenance crews and plant engineers joining dissimilar pipe sizes without adapters. California Proposition 65 warnings apply to substances in the material.

Installers Needing Straight Thread Reduction

The fitting serves teams reducing line diameter on NPT threaded networks without welding or flanges. It is not for installers who require socket-weld, butt-weld or compression ends. Buyers needing different alloy grades or larger step-down ratios must source alternative fittings. The coupling ships direct from the manufacturer on orders over 75.

316 Stainless Steel FNPT x FNPT Construction

The single deciding specification is the 316 stainless steel construction with female NPT threads on both ends. This alloy and thread combination determines chemical compatibility and sealing method for the installation. Verify the material grade and thread standard match the system design before ordering.

Questions about this item

Will the 1-1/2" x 3/4" SS316 reducing coupling thread directly onto my existing FNPT pipework?

Yes, the coupling uses FNPT threads on both ends so it connects to standard NPT pipe threads without adapters.

How can I verify the 316 stainless steel reducing coupling is sealing correctly after installation?

Pressurise the system and check the joint for leaks; a properly threaded FNPT connection with sealant should show no weeping.

Does the box contain thread sealant or tape for the FNPT connections, or must I buy it separately?

The package includes only the reducing coupling; thread sealant or PTFE tape must be purchased separately.
