Great Britain took seven gold medals and set four world records on day three of the IPC World Championships.
Gareth Duke, 20, led the way in Durban, with victory and a new global best in the SB6 100m breaststroke.
Liz Johnson won the women's version while Sascha Kindred defended his SB7 100m breaststroke title.
Danielle Watts won the S1 200m freestyle, while Anthony Stephens (S5 200m free), Kenny Cairns (S3 200m) and the women's 4x50m team all struck gold.
The quartet of Jane Stidever (Leicester Penguins), Fran Williamson (Colchester Phoenix), Johnson and Natalie Jones (Colchester Phoenix) took the title in 3:14.53.
"That was my first major final so I'm delighted to win the gold medal
Earlier, Duke touched first in his event in one minute 27.04 seconds, knocking more than a second off the previous best set by American Travis Mohr, who was second in the race.
"I'm so pleased to get that record," he said.
"I was looking out for Travis and he was quite close on the second length, but I managed to pull away on the last 25m and take his record."
Duke's Swim Swansea team-mate Johnson also had another good reason to celebrate a day after her 21st birthday when she touched five seconds ahead of her closest rival in 1:40.83.
"That was my first major final so I'm delighted to win gold," she said.
"I first broke the record this time last year so it's obviously a good time to race for me."
A further four silvers pushed Britain's medal total to 11.
Fran Williamson reached the podium for the second time this week by securing another individual silver in the S3 200m freestyle.
Jim Anderson (Broxburn) also collected silver over 200m, finishing second in the S2 classification in 4:58.84 behind Russia's Dmitry Kokarev.
European records also tumbled in the 34-point Medley relays as both Britain's teams took silver.
The boys team of David Hill (Kelly College), Callum Lawson (Nova Centurion), James Crisp (City of Sheffield) and David Roberts (Swim Swansea) romped home behind world record-breaking Australians for silver in 4:28.26
And the women's quartet of Kate Grey (Thornbury), Claire Cashmore (Kelly College), Rachael Latham (Horwich Leisure Centre) and Louise Watkin (Kelly College) bagged silver in 5:14.56.
