The VETUS GRP Tunnel — 150mm Internal Diameter — 1500mm Length is a purpose-built marine component designed for professional and recreational boaters who demand reliable thru-hull plumbing and bow thruster ducting. This fiberglass-reinforced polyester tunnel delivers the structural integrity and longevity required in saltwater and freshwater environments where corrosion and material fatigue can compromise standard steel or aluminum alternatives. Whether you're outfitting a center console, cruising vessel, or specialty boat, this tunnel provides the backbone for clean, protected water passage and thruster operation.
Engineered from high-grade fiberglass-reinforced polyester (GRP), the VETUS tunnel resists osmotic blistering, UV degradation, and chemical attack far better than unprotected resin systems. The 150mm internal diameter accommodates standard bow thruster intake and discharge piping, while the 1500mm length spans typical hull thicknesses and supports modular installation across diverse hull designs. The material's inherent rigidity eliminates the vibration and flex that plague lighter-gauge alternatives, ensuring smooth thruster operation and minimal noise transmission to the cabin. This construction method also allows for consistent wall thickness and dimensional accuracy, critical for pressure-tight sealing and long-term reliability in demanding marine service.
This tunnel is ideal for boat builders, marine mechanics, and yacht owners upgrading or restoring thruster systems on vessels requiring premium through-hull components. Installation requires proper bedding compound, mechanical fastening, or adhesive bonding depending on hull construction type — always follow VETUS installation guidance and marine engineering standards specific to your vessel. The lightweight profile (1 lb) simplifies handling during installation while maintaining exceptional durability, and the neutral GRP composition eliminates galvanic corrosion concerns when paired with standard marine fittings and pumps.
