Tru- Design glass-reinforced nylon composite thru-hull fittings and ball valves now meet or exceed ABYC H-27 and ISO 9093-2 requirements by utilizing a Load Bearing Collar. Offering ease of installation and uncompromising strength, they’re designed for boatbuilders who don’t want to drill additional holes in their hulls, or deal with the hassles of bonding or gluing a thru-hull fitting into place.
The non-corroding thru-hull fitting, load bearing collar and ball valve system can eliminate problems associated with metal and bronze sea cocks, such as corrosion and electrolysis. Unlike sea cock with flange models, Tru-Design collars spread the load evenly, so they don’t require any gluing or fasteners to the hull.
This system can be retrofitted to existing thru-hull assemblies. The lightweight valves are designed for long-term use since their PTFE ball and seals won’t seize.
When in place, the thru-hull fitting-ball valve-tail assembly can withstand a 500 lb. static force for a minimum of 30 seconds. Tru-Design thru-hull fittings are compatible with all hull types across a wide range of thicknesses and can be used on aluminum, steel, wood, GRP or composites. They are available for 1/2″, 3/4″, 1″, 1-1/4″, and 1-1/2″ sized units. A shrouded covering protects vulnerable areas, such as the exposed thread of the thru-hull fitting, from being inadvertently struck by loose items.
Available in small and medium sizes, the collar is part of Tru-Design’s complete thru-hull system. The 3/4″ thru-hull with ball valve and collar is $114, while the collar alone is $10.
