Forespar® series of the Thru-Hull Connectors are precision molded in high strength Marelon®. Their great strength, light weight and complete freedom from corrosion and electrolysis make them the ideal Thru-Hull Connectors for use above or below the waterline. All Thru-Hull Connectors must be installed with proper bedding compound. We recommend a maximum torque setting of 20 lb/ft for Series 250, Series 251 and Series 253 Thru-Hull Connectors. The 'S' notation in our model numbers (e.g. CF 2505 1/2), indicates a Thru-Hull Connector that has been fitted with a strainer.
