4 inch galvanized cap for plumbing

California Proposition 65 warnings included

The product carries two California Proposition 65 warnings regarding chemicals known to cause cancer and reproductive harm. These notices inform safe handling practices during installation. No additional accessories or software are bundled with this fitting. The warnings do not alter the mechanical function of the cap.

Verify thread size and material compatibility

Confirm the existing pipe uses a matching 4 inch male NPT thread before ordering. Ensure galvanized steel is compatible with the system fluid and adjacent metals to avoid galvanic corrosion.

Questions about this item

Will the galvanized coating on the 4 inch cap need replacement after years of service?

The galvanized finish protects the steel threads from corrosion; under normal water conditions it lasts many years without maintenance.

What pressure limit appears first when the 352-491 cap is left under constant system pressure?

The cap is rated for standard residential plumbing pressures; the galvanized threads remain the limiting factor if pressure exceeds design values.

Does the 4 inch galvanized cap generate heat or noise when the plumbing runs all day?

As a passive threaded fitting it produces no noise, no heat and draws no power during continuous operation.
