AirCraft O-Ring Repair Kit For SG A178 (Parts 2, 12 & 14) (SG A178-04)
At a Glance: Replacement O-ring seal kit for SG A178—fixes leaks and restores consistent air/media flow.
Small seals, big impact. The AirCraft SG A178-04 O-ring repair kit is the go-to refresh pack for your SG A178 sandblaster/etcher (air eraser style tool), replacing the key O-rings referenced as parts 2, 12 and 14. When O-rings harden, flatten or tear, you get the classic symptoms—hissing leaks, inconsistent blasting, poor suction and wasted air. Swap these seals and you bring the tool back to tight, efficient operation with a smoother, more predictable blast.
The SG A178 relies on airtight joints to maintain proper pressure and media pickup. Fresh O-rings help stop air leaks, stabilise flow and reduce the “random behaviour” that happens when seals are past their prime.
