Choosing the right fitting in the marine pumps plumbing sanitation aisle comes down to one question: are you turning a line through a tight run, or are you taking it through the hull? One listing here is a street elbow option; the other is a 90-degree thru-hull fitting. Both are elbow-style pieces, but they serve different spots in the system. The street elbow listing offers a quantity of elbows to spread across a project, while the thru-hull is a purpose-built hull piece. The right pick depends on whether you need several in-board corners or one clean hull exit.
Quick verdict: If you want brass elbows for multiple connections, the STREET ELBOW BRASS PLUMBING FITTING SET is the right listing at $9.98. If you need a hull exit for a hose, the Marine/Boat 90 Degree Thru Hull Plumbing Fitting is the better buy at $8.99 and comes with a one-year warranty.
| Listing | Price | What you get | Condition |
|---|---|---|---|
| STREET ELBOW BRASS PLUMBING FITTING SET | $9.98 | Set of five brass street elbows with male/female ends; roughly 1 1/8-inch length x 5/8-inch width; 1/2-inch female and 3/8-inch male inside diameters | New other (see details) |
| Marine/Boat 90 Degree Thru Hull Plumbing Fitting | $8.99 | One 90-degree thru-hull fitting for a 3/4-inch hose; UV- and chemical-resistant virgin polypropylene; finished head and single pass around nut | New |
Where each product wins:
- The street elbow set wins when you want a quantity of metal elbows for tight corners and don't need a hull-penetration piece.
- The thru-hull fitting wins when the job is a clean right-angle exit through the hull.
STREET ELBOW BRASS PLUMBING FITTING SET
The strongest point of this listing is that it gives you five brass street elbows in one purchase. Each elbow has a male end and a female end, which is convenient when you are making several connections in a plumbing run. The brass color and metal build make it a straightforward choice for boat plumbing. Before committing, check the approximate dimensions: 1 1/8-inch length by 5/8-inch width, with a 1/2-inch female inside diameter and a 3/8-inch male inside diameter. Those sizes determine whether the fittings will match your hose or pipe. This is an elbow set rather than a thru-hull piece, so it works best for the corners on the inside of the boat rather than for a hull opening.
Marine/Boat 90 Degree Thru Hull Plumbing Fitting
This fitting is the one to pick when the hose has to make a right-angle turn and exit the hull. It is made from UV- and chemical-resistant virgin polypropylene, with a finished head and a single pass around nut, and it carries a one-year warranty. Those details make it a strong fit for a hull location. The trade-off is that you get only one fitting, so a project with more than one thru-hull opening means buying additional units. The fit is also specific to a 3/4-inch hose, which is ideal if that is your line size but not a universal replacement for all hose diameters.
Final choice by use case: For a hull opening in a hose installation, choose the Marine/Boat 90 Degree Thru Hull Plumbing Fitting. For in-board bends where you need a handful of brass elbows, choose the STREET ELBOW BRASS PLUMBING FITTING SET. If your project has both, use the thru-hull at the hull and the brass elbows for the corners inside.
