The Malaysian pair came out tops in the final at the Bac Tu Liem Sporting Centre after earning 9,905 points to beat their challengers Hazim Zaque and Haziq Zaque.
The sibling pair from Singapore collected 9,905 points for the silver while the bronze was shared by host pair Duc Danh Tran-Hong Que Le and Abdul Karim Yusoh-Khairulmahadi Yusoh from Thailand.
Malaysia’s gold is the first non-diving medal at the Games, bringing the tally to seven.
When met by reporters after the final, a satisfied Sazzlan described the achievement as a boost ahead of the World Pencak Silat Championships in Kuala Lumpur next July.
He said as defending champions, he and Taqiyuddin competed in the final without pressure and focused on giving their best today.
The gold in Hanoi is the third for Taqiyuddin who previously topped the event in the 2017 edition in Kuala Lumpur with Rosli Sharif before teaming up with Sazzlan at the 2019 Games in the Philippines.
