The Brumbies held off a late comeback from the Hurricanes to win 30-23 in Canberra and maintain their lead in the Australian Conference.
The Brumbies went out to a 30-16 lead in the second half but the Hurricanes fought back and closed the gap to seven points but could not level the scores despite a mountain of late territory.
With 15 minutes left Hurricanes scrum-half TJ Perenara scored a converted try for his team and with the conversion they trailed by seven points.
The Hurricanes dominated play for much of the final 10 minutes and had a try disallowed that would have pulled them within two of the lead.
Despite the pressure Brumbies' defence held out to protect their lead and stretch their conference lead to nine points over the Reds.
The result moved the Brumbies provisionally to second place 54 points which is two points behind the tournament-leading Chiefs.
The Reds will get the chance to keep in touch with the Brumbies should they beat the Melbourne Rebels in Brisbane on Saturday.
The loss has likely cost the Hurricanes the chance of making the playoffs with three New Zealand derbies left.
The Brumbies led 11-3 early on, through a try from scrum-half Nic White, but a converted try by Reynold Lee-Lo got the Hurricanes back to 11-10.
Christian Lealiifano gave the home side some breathing space with a penalty goal to lead 14-10 at half-time.
The Brumbies looked to have the match in their keeping after a try to blindside flanker Peter Kimlin with 20 minutes left.
But the Hurricanes finished strongly, first through a converted try to Perenara and then a disallowed TMO decision in the corner to captain Conrad Smith.
The Hurricanes stormed the Brumbies line and turned down several penalty shots at goal in pursuit of an equalising converted try before an accidental offside allowed the Brumbies to escape with a narrow win.
Lealiifano kicked a total of 20 points, with six penalties and a conversion with his only blemish being a tough conversion attempt following White's first-half try.
"To get that win is super important for our season and it allows the boys to really focus on the Rebels next week," Brumbies skipper Ben Mowen said.
"The attitude tonight was outstanding and times there we just had to graft for points but that's the disciplined play you need."
Captain Conrad Smith said ill-discipline cost his Hurricanes victory.
"We probably left it a bit late, but when we held the ball we played some pretty good rugby and there were a lot of penalties and that was from our mistakes for a lot of the time," Smith said.
"That discipline costs you and it's a tough competition but we just have to take it on the chin now."
The Brumbies face the Rebels in Canberra next week, while the Hurricanes will have three weeks off in the international break before tackling defending champions Chiefs in Hamilton on June 28.
