Industrial plumbing reducer

The Legend Valve 416-488 is a 316 stainless steel hex bushing that joins a 1-1/4 inch female NPT port to a 3/4 inch male NPT thread. It is built for installers who need a corrosion-resistant step-down fitting in water, chemical or compressed-air lines. The material suits harsh environments where carbon steel or brass would degrade.

Replaces larger female ports

This bushing lets you adapt an existing 1-1/4 inch FNPT opening to accept 3/4 inch MNPT pipe or components without cutting or re-threading. The upgrade is worth it when the system demands 316-grade alloy for chloride resistance or when the pressure rating of the original fitting must be maintained. It does not serve lines that require a straight coupling or a different thread standard.

NPT thread sealing limits

Tapered NPT threads rely on thread interference and sealant to prevent leaks, so proper tape or compound application is essential. The hex body allows standard wrench engagement but offers no integral sealing face beyond the threads themselves. Over-tightening can distort the stainless material and create weep paths. California Proposition 65 warnings apply to this product.

Questions about this item

What thread sizes does the 1-1/4 in x 3/4 in hex bushing connect?

The bushing reduces a 1-1/4 inch female NPT opening to a 3/4 inch male NPT thread for direct pipe connection.

Which wrench flats should I use when installing the 316 stainless steel hex bushing?

Tighten only on the external hex flats; turning the bushing by the pipe threads can strip the NPT profile.

How does the 316 stainless steel material affect long-term replacement planning?

316 stainless resists corrosion in water and chemical lines, so the bushing typically outlasts the surrounding pipe and rarely needs scheduled replacement.
