Forespar® series of plastic Thru-Hull Connectors are precision molded in high strength Marelon®. Their great strength, lightweight, and complete freedom from corrosion and electrolysis make them the ideal Thru-Hull fittings for use above or below the waterline.
All Forespar® marine Thru-Hull fittings must be installed with proper bedding compound. We recommend a maximum torque setting of 20 lb/ft.
