Product identity

The Legend Valve 304-146 is a 1-1/2 inch by 4 inch pipe nipple manufactured from 304 stainless steel. It serves industrial plumbing installations that require corrosion-resistant connections between threaded fittings.

Upgrade path

This nipple replaces carbon-steel or lower-grade alloy nipples in systems exposed to moisture, chemicals or elevated temperatures where rust would compromise joint integrity. The jump is worth it when the piping network must maintain purity and structural strength over long service intervals.

Material limits

304 stainless steel resists many common corrosives but can suffer pitting or stress-corrosion cracking in high-chloride environments such as coastal atmospheres or concentrated brine lines. California Proposition 65 notices indicate the product contains chemicals identified by the state as causing cancer and reproductive harm.

Highlights

Questions about this item

What thread size must the mating fitting have to accept this 1-1/2" stainless nipple?

The nipple has 1-1/2" NPT threads on both ends, so the mating fitting must provide a matching 1-1/2" NPT female connection.

What is the common mistake when installing this 304 stainless nipple into a threaded joint?

Over-tightening the nipple can distort the 304 stainless threads and cause leaks; tighten only until the joint is snug and sealant is engaged.

How often should the 304 stainless nipple be inspected for corrosion in a potable-water system?

Inspect annually; 304 stainless resists general corrosion but can develop pitting in high-chloride water, so replace if any pitting or discoloration appears.
