Product identity

This Legend Valve 304-226 nipple is a hydraulic system component manufactured from 304 stainless steel. It is supplied new and intended for joining two sections of 4" piping in fluid-power circuits.

Fit and exclusions

The part suits installers who need a straight, corrosion-resistant connector for 4" stainless pipe in hydraulic applications. It is not for buyers who require a different nominal bore, a threaded adapter, a reducing fitting or a material other than 304 stainless steel.

Deciding specification

The 304 stainless steel construction determines chemical compatibility and corrosion resistance in the hydraulic system. California Proposition 65 warnings indicate the product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

Questions about this item

What thread size and material does the 4" x 4" 304 SS nipple require for a leak-free hydraulic connection?

The nipple is machined from 304 stainless steel with 4-inch NPT threads on each end; match the same thread specification and use a compatible stainless fitting to avoid galvanic corrosion.

Which sealing method works best when installing this 304-226 nipple, and what common mistake causes leaks?

Apply PTFE tape or pipe dope on the male threads only, then tighten to the recommended torque; the frequent error is over-tightening, which distorts the 304 SS threads and creates a weep path.

How often should the 304 stainless nipple be inspected or replaced in a high-cycle hydraulic system?

Inspect the threads and sealing surfaces at every scheduled fluid change; replace the nipple if you see galling, corrosion pitting, or deformation, typically after several thousand pressure cycles depending on fluid cleanliness.
