When you're working on your boat's plumbing, you may be deciding between two stainless steel marine parts that look similar but do very different jobs. The 316 Stainless Steel 1in Thru Hull Fitting is for bringing water in through the hull, while the Scandvik Stainless Steel Washdown Spigot 10187P is for sending water out at the deck to wash things down. That job difference matters more than the price spread.
Quick Verdict
If you're connecting a water intake, bilge pump, or livewell, the 316 Stainless Steel 1in Thru Hull Fitting is the part to pick. If you're setting up a deck washdown system, the Scandvik 10187P is the specialized spigot you want. Match the part to the job and you'll get a stainless steel marine plumbing solution that makes sense.

Product Notes
316 Stainless Steel 1in Thru Hull Fitting

Start here if you need a 1-inch thru hull fitting for an above-waterline plumbing task. This fitting is designed for marine systems, with a stainless steel construction that gives it a rugged feel. It's silvery in color with a solid pattern, weighs about 8.1 ounces, and ships as a new part. The main thing to keep in mind is the warning that it's not recommended for use below the waterline, so plan your installation accordingly. If your project is above the waterline and you want a functional thru hull fitting without the big price tag, this is the one.
Scandvik Stainless Steel Washdown Spigot 10187P

If you want a deck-side fixture that looks sharp and handles saltwater duty, this Scandvik washdown spigot is the specialized option. It's meant for marine deck washdown systems, with a polished stainless steel body and a corrosion-resistant, marine-grade build. The intended uses are anchor washdown, deck cleaning, and bait wells, so it fits the chores that keep a boat tidy between trips. It's new, works with boats, yachts, and marine vessels, and comes from Scandvik. The trade-off: it's a deck spigot, not a thru hull fitting, so it won't handle water intake or bilge-pump connections. If that's your project, this spigot is the right piece.

- Need a thru hull fitting for your boat's plumbing? Choose the 316 Stainless Steel 1in Thru Hull Fitting, and keep it above the waterline.
