Description
GROCO 1" Extra Long Bronze Thru-Hull w/Nut | Boat Supply Store
For vessels requiring extended hull penetration, this GROCO 1" extra-long thru-hull fitting ensures a robust and reliable seal. Constructed from C83600 Bronze, it offers superior resistance to saltwater corrosion, a critical factor for offshore catamarans operating in the Gulf of Mexico. The fitting features a versatile NPSM/NPT combination thread, accommodating a wider range of plumbing connections than standard NPT-only fittings. Its substantial length is engineered to address the complexities of thicker hull constructions or installations requiring significant material engagement.

Common Concerns Answered
How do I find a replacement for an older thru-hull if the length is non-standard?
The extra-long design of this GROCO fitting is specifically engineered to address situations where standard lengths do not suffice, often serving as a direct replacement for older, less common thru-hull dimensions, mitigating installation challenges.
Is the combination thread type a complication for installation?
While some may prefer a single thread type, the NPSM/NPT combination thread on this GROCO fitting offers enhanced versatility, allowing connection to both parallel (NPSM) and tapered (NPT) fittings, which can simplify plumbing runs in complex installations.
Why is this bronze thru-hull more expensive than plastic alternatives?
The investment in C83600 bronze construction ensures superior longevity and corrosion resistance compared to plastic, making it a critical choice for the integrity of your vessel's hull penetrations, especially in demanding marine environments.
