In Saturday’s other Pool A game, Exeter Chiefs overcame Bristol Bears with a hard fought 22-17 win at Sandy Park.
Will Rigg was the first on the scoresheet, crashing over the line from short range before captain Louie Gulley extended the Chiefs’ lead.
Aidan Boshoff responded for the visitors following Max Lahiff’s drive upfield before Rigg secured a deserved second after the break.
Not to be outdone, Boshoff then claimed a brace of his own with 10 minutes to go, but Bristol were unable to breach the home defence in the dying moments.
With each side having played four games Gloucester lead the group with 15 points, three ahead of Sale with Bath a further point back.
Exeter’s win moved them above Bristol into fourth place on eight points, two clear of the Bears.
