The Sealey GSA312 is a pneumatic air riveter designed for professional assembly work across aluminium, steel and stainless steel rivets up to 3/16″. Engineered for heavy-duty applications, this trigger-operated tool combines robust construction with user comfort features for demanding workshop and site environments. Built around a hardened steel jaw assembly, the GSA312 delivers reliable performance across multiple rivet sizes. The composite handle provides effective insulation against cold and vibration during extended use, reducing operator fatigue. A rivet shaft safety cap offers protection during operation, whilst the 90psi operating pressure ensures consistent riveting force. Supplied complete with four nozzle sizes (3/32″, 1/8″, 5/32″ and 3/16″) and two spanners, this air riveter handles diverse riveting tasks without requiring additional accessories. The 1/4″ BSP air inlet provides standard compatibility with workshop air systems, whilst the 4cfm air consumption maintains efficient operation. At just 1.3kg, the tool remains manoeuvrable for overhead and awkward-angle work.
