Pipe Nipple for Air Gases and Non-Potable Water

This Beck steel pipe nipple is manufactured in the USA from Grade B welded steel with a black anodized finish. It features 1 inch NPT threads on both ends and an overall length of 71/2 inches. The component is designed for use with air, gases, non-potable water, and oils in industrial piping systems.

Pressure Ratings up to 300 psi at 150 Degrees F

The fitting handles a maximum operating pressure of 300 psi at 150 Degrees F and a maximum steam pressure of 150 psi at 360 Degrees F. An inside diameter of 1 3/64 in provides flow capacity for the nominal 1 inch pipe size. No minimum or maximum operating temperature limits are specified by the manufacturer for general service.

Replaces Worn or Damaged Threaded Steel Nipples

This nipple serves as a direct replacement for existing 1 inch NPT steel nipples of the same length and pressure class where the original has corroded or leaked. The jump is worth it when system pressure demands the 300 psi rating at elevated temperature or when a USA-made Grade B weld specification is required by code. It is not suited for potable water lines or applications requiring certified lead-free materials.

Questions about this item

Will the 1 in NPT threads on this steel nipple mate with the 1 in NPT fittings already on my older black-iron piping?

Yes, the nipple has 1 in NPT threads on both ends, the standard taper thread used on black-iron pipe, so it will thread directly onto your existing fittings.

How can I verify the nipple is holding pressure correctly after I install it in a 300 psi air line?

Pressurise the system to its working pressure, then brush soapy water on each joint; steady bubbles indicate a leak, while no bubbles confirm the 300 psi rating is being met.

Does the package include thread sealant or gaskets, or do I need to buy them separately?

The box contains only the 71/2 in steel nipple with black anodised finish; pipe-thread sealant or PTFE tape must be purchased separately.
