It creates a seal and holds the elbow in place but (in the case of blue) allows the elbow to be easily removed again. Chances are you won't create a seal without it. You can pick the stuff up for £2.50 for any halfords.Roger that bob. When puttin the elbow back onto my new on/off is the loctite nesecary?

Get a pair of pliers and an adjustabe wrench. Use the adj wrench to put pressure on the elbow collar, grab the macroline with the pliers and pull like you've nevered pulled before. Be warned though, you may have to change the macroline after doing that depending on the damage the pliers does.Ok the elbow is off and gonna shoot up to halfords now to get the loctite 242....now all i have to do is get this peice of pesky macroline that just doesnt want to come out...
