DIXON 3/4 KING NIPPLE

Description & Features

Designed for reliable male NPT connections in industrial fluid systems, the Dixon 3/4 King Nipple is a combination-style fitting with a knurled wrench grip for secure installation and removal without tool slippage. The 3/4 in. male NPT thread size suits a wide range of standard fittings and inline components commonly used in hydraulic and fluid transfer assemblies.

Manufactured by Dixon Valve & Coupling, this combo nipple is built to the quality standards associated with the Dixon King series line. The knurled grip surface provides a practical advantage in tight or high-torque installation environments where a smooth body would be difficult to handle.

What size wrench do you need to tighten this nipple down properly? Don't want to strip it out.

Answer by: Customer Support on Oct 5, 2025, 6:50 AM

That knurled section is there to give you a good grip with a wrench. It's designed to help prevent slippage, especially when you're working in tight spots or need to apply a good amount of torque.

trying to swap out a nipple on a line, is this one actually 3/4 male NPT?

Answer by: Customer Support on Aug 21, 2025, 6:58 AM

Thread-wise, it is a 3/4 in. male NPT combo nipple, so it’s meant to make a standard male NPT connection in an industrial fluid system.

Question by: Kurt R on Oct 7, 2025, 9:07 AM

Got a knurled body on this thing, so I'm guessin it's meant to be turned by hand or with a strap wrench? Just want to know if I actually need a pipe wrench to seat it right.

Answer by: Customer Support on Oct 9, 2025, 8:50 AM

The knurled grip is there to give you something to hold onto without your hands or wrench slipping off, especially useful when you're working in a cramped spot or dealing with high torque. You can use a strap wrench or similar tool with it, but the knurling is really about giving you a secure surface to work against rather than replacing a wrench entirely. For a proper seated NPT connection, you'll want to make sure it's tightened down enough to form a good seal, so don't rely on hand-tightening alone.
