Seal Protector Large Body

The QA1 Seal Protector Large Body is a precision marine seal designed to protect critical bearing and pivot points on your vessel's steering, trim, and structural assemblies. Whether you're running a center console through rough offshore conditions or maintaining a cabin cruiser in saltwater, this seal prevents corrosion, water intrusion, and bearing wear that can compromise handling and safety on the water.

Built to withstand the constant motion and environmental stress of active boating, this large-body seal is engineered to fit QA1 bearing assemblies and trim cylinders. It uses elastomer and metal construction to create a watertight barrier against saltwater, freshwater, and sediment contamination. The compact profile allows installation in tight mounting spaces without sacrificing sealing integrity or load capacity.

Its lightweight design makes it easy to handle during installation or replacement, while the precision-molded construction ensures consistent fit and performance across multiple boating platforms and manufacturers that spec QA1 components. Boaters performing routine maintenance on tilt-and-trim systems, steering linkages, or suspension components will benefit from having this seal on hand as both a preventive replacement and emergency backup.
