  • Connects two 2-1/2 inch NST hoses securely

ZORO SELECT 2-1/2 Inch MNST Hex Nipple

This straight hex nipple connects two female NST threads of identical size. The brass construction resists corrosion in fire-suppression and industrial water systems. Installers tighten the fitting with a standard wrench on the external hex.

Suits fire-service crews joining 2-1/2 inch NST

Not for installers who need a reducing coupling or a swivel connection. Not for systems that require a different thread standard such as NPT or BSP. Buyers needing a female-to-female adapter should select another fitting.

2-1/2 inch NST male-to-male thread size

This single dimension determines whether the nipple matches the existing hose or appliance threads. Verify the thread standard and nominal size on both mating components before purchase. The brass material suits potable and fire-water service.

Questions about this item

Is this the only size and connection type available for this hex nipple?

The fitting is a 2-1/2 inch straight rigid hex nipple with male NST threads on both ends, made of brass.

What does the California Proposition 65 warning mean for someone installing this coupling?

The product contains a chemical known to California to cause cancer and birth defects or other reproductive harm; follow safe handling practices during installation.

How does the NST thread standard affect what hoses or equipment this nipple connects to?

Both ends use National Standard Thread (NST), so it joins two female NST fittings of the same 2-1/2 inch size in fire hose or compatible plumbing systems.
