Flexeel Max has all the features and benefits as Flexeel, except it also includes a 300 PSI pressure rating, a ball swivel coupler for easier tool maneuverability, an air safety plug to prevent dangerous hose whip and an "Eel Strap" for convenient storage and carrying. The high visibility "Eel Green" color is easy to see and helps to keep the work area safe from accidental tripping due to unseen obstacles.
