Industrial Plumbing Locknut

The Legend Valve 416-169 is a 2-1/2 inch locknut manufactured from 316 stainless steel for industrial plumbing installations. It features FNPT threading and a 290 psi pressure rating suitable for demanding fluid-handling systems. This component is designed for professionals requiring corrosion-resistant connections in harsh environments.

Capacity And Pressure Headroom

The 290 psi rating provides headroom for standard industrial water, oil, and gas lines operating well below this limit. The 316 stainless construction resists chemical attack that would degrade lesser alloys in corrosive service. The locknut will not withstand pressures exceeding its rated maximum or temperatures beyond the material's mechanical limits.

316 Stainless Steel Material

The defining specification is the 316 stainless steel alloy, which determines chemical compatibility and service life in chloride or acidic media. Buyers needing a lower-cost carbon steel or bronze fitting for non-corrosive duty should select a different material grade. This locknut is not intended for applications requiring exotic alloys such as Hastelloy or titanium.

Questions about this item

Will the 2-1/2 in FNPT threads on this 316 stainless locknut mate with my existing piping?

The locknut has 2-1/2 in FNPT threads; it will engage with any matching 2-1/2 in MNPT fitting regardless of pipe schedule.

How can I confirm the 316 stainless steel locknut is sealing at its rated 290 psi after installation?

Pressurise the system to the working pressure and inspect the joint for leaks; a properly threaded 316 stainless locknut should hold 290 psi without weeping.

Does the box contain only the 416-169 locknut or are gaskets and pipe tape included?

The shipment contains the 416-169 316 stainless steel locknut only; thread sealant or gaskets must be purchased separately.
