Product Identity

The Legend Valve 416-126 is a 1-1/4 inch stainless steel 316 threaded cap with female NPT threads. It is designed for industrial plumbing systems requiring corrosion-resistant closure at pressure class 290.

Installation Notes

The cap threads onto a male NPT fitting using standard pipe sealant or tape for a leak-free joint. Stainless steel 316 resists galling better than lower grades, but clean threads and proper lubrication prevent binding during assembly.

Standard Limits

Female NPT threads seal by taper interference and require sealant to block the spiral leak path. The 290 pressure class defines the maximum non-shock working pressure at ambient temperature; elevated temperatures reduce the allowable pressure per applicable piping codes. California Proposition 65 warnings apply to this product.

Questions about this item

How do I confirm the 316 stainless steel cap is sealing correctly after threading it onto a 1-1/4 in Female NPT fitting?

After installation, pressurise the system to the 290 rating and inspect every joint for leaks; a properly seated cap will hold pressure without weeping at the threads.

What components are included with the 416-126 cap and what additional items are required for installation?

The package contains only the 316 stainless steel threaded cap; you must supply compatible 1-1/4 in NPT pipe or fittings and suitable thread sealant or tape separately.

When should I choose the 416-126 model over other Legend Valve caps?

Select the 416-126 when you need a 1-1/4 in Female NPT cap in 316 stainless steel rated for 290 service; other models differ in size, material or pressure class.
