NECO® 4 Bolt Hose Clamps

4 Bolt Clamp is specifically made to work with the Air supply Hose and the 4 lug hose end.  It is made out of plated ductile iron for superior strength. 2″ 4 bolt clamp is made from Carbon Steal.  Insert the barbed shank end of the 4 lug hose end into the air supply hose and then hold secure with a 4 bolt clamp.  The special lip molded into the hose end holds the clamp securely in place.  Alternate tightening the four bolts until they are all tight.  This will keep both sides of the clamp equally tight so as to create a good pressure seal.   Stay Safe by using a whip check cable around your air hose and equipment.  And don’t forget to put a pin in it!!!
