Frequently Asked Questions
What is the thread type on the GROCO 2-1/2" Bronze Combo Scoop Thru-Hull?
This thru-hull fitting features an NPSM/NPT combination thread, providing versatility for various plumbing connections.
What material is the GROCO 2-1/2" Bronze Combo Scoop Thru-Hull made from?
It is constructed from C83600 Bronze, a highly corrosion-resistant alloy suitable for marine applications.
What is the purpose of a scoop thru-hull fitting?
A scoop thru-hull fitting is designed with an outward-facing scoop to accelerate water flow into the hull, significantly increasing intake efficiency compared to a straight-faced fitting.
What does the NPSM/NPT combination thread mean?
The NPSM (National Pipe Straight Mechanical) thread is designed for mechanical joints using a gasket or O-ring, while the NPT (National Pipe Taper) thread is tapered and seals by wedging. The combination allows for adaptable connections.
What is the flow rate advantage of this scoop thru-hull compared to standard thru-hulls?
While specific flow rate figures vary with installation and pipe diameter, the scoop design inherently increases water velocity and volume entering the fitting, providing a significant flow advantage over standard straight-faced thru-hulls for applications requiring high water volume.
