Pipe Nipple for Air, Gas and Water Lines

This 1/2 inch galvanized steel nipple connects Schedule 40 piping in air, gas and potable water systems. Electric resistance welded construction provides a leak-resistant joint. The corrosion-resistant coating protects the steel in damp environments. Rated for 300 psi at 150 degrees F and 150 psi steam at 350 degrees F.

Suits Standard Schedule 40 Installations

Installers working with 1/2 inch nominal pipe size and Schedule 40 fittings can use this nipple directly. The 4 inch overall length fits common spacing requirements. Builders needing a different nominal diameter, wall schedule or longer reach should select another fitting. Systems exceeding the stated pressure or temperature limits require heavier components.

Handles 300 psi Water and 150 psi Steam

The fitting comfortably handles standard water pressures up to 300 psi at 150 degrees F. Steam service is rated to 150 psi at 350 degrees F. Beyond these pressures or temperatures the nipple reaches its design limit. The 53/64 inch outside diameter matches Schedule 40 dimensions for compatible threading.

Questions about this item

What male-threaded fitting do I need to connect this 1/2 in MNPT nipple to my existing pipe?

You need a 1/2 in female NPT fitting such as a coupling, elbow or tee that matches Schedule 40 dimensions to thread onto the nipple's male ends.

Will this Schedule 40 galvanized nipple handle the same 300 psi at 150 °F rating as my existing Schedule 40 steel pipe?

Yes, the nipple is rated for 300 psi at 150 °F and 150 psi steam at 350 °F, matching standard Schedule 40 pressure classes for air, gases and potable water.

How can I verify the nipple is sealed correctly after threading it into both fittings?

Pressurise the line up to the 300 psi rating and check each joint for leaks; the galvanized coating and electric-resistance weld should hold without weeping when properly tightened.
