4 Lug Female NPT

$10.00$10.71

Description

The 4 Lug Female NPT coupling has female NPT threads to screw onto your machine or devise.  The 4 lug end matches up with the 4 lug hose end that you would have on a 1-1/2 inch air supply hose.   In other words, the female end would go on the machine and the 4 lug end would receive your air line.

This 4 Lug Female NPT coupling comes in 3 sizes; All of which are in stock.  Additionally, all of them are made out of plated ductile iron and all have the same size 4 lug end.

Stay Safe by using a safety pin in the pre-drilled hole on the 4 lug side.  Stay even safer by using a whip check cable around your air hose and equipment.
