OPENING TRY ... Sebastien Chabal
The Sharks have now gone an incredible 5hr 20min without conceding a try this season.
Sale director of rugby Philippe Saint-Andre said: “I don’t know how long the run can go on for.
“But the defence is all about organisation and commitment and the guys are working very hard for each other. I’m very pleased with the performance.”
The sides traded penalties to leave the half-time score at 6-6 before Sale brought the game to life.
Sub Dwayne Peel off-loaded to Sebastien Chabal and he crossed the line for the opening try and wing David Doherty finished off a fine flowing move to add a second score with 10 minutes left.
The result takes Sale to the top with four wins from four.
Gloucester coach Dean Ryan said: “It was a fierce kicking contest and we came second.”
