<h3>About Seachoice: Built by Boaters, for Boaters</h3><p><strong>Seachoice</strong> has been one of the most trusted names in the marine industry since its founding in 1988. What started as a focused supplier of marine hardware — cleats, hinges, and hasps — has grown into a comprehensive resource for boating enthusiasts of every level. Today, Seachoice offers more than 5,000 high-quality marine parts and accessories across 17 categories, backed by distribution from 18 warehouse locations for fast, reliable availability wherever you are on the water.</p><p>The philosophy behind Seachoice is straightforward: deliver the products boaters actually need, at a quality level they can depend on, without breaking the bank. That commitment has made Seachoice a go-to brand for both weekend recreational boaters and serious on-water professionals alike. Every product in the lineup is covered by a no-hassle warranty, reflecting the brand&quot;s confidence in its own craftsmanship.</p><h3>Anchoring Solutions for Every Vessel</h3><p>Anchoring is arguably the most critical system on any boat, and Seachoice has built an extensive anchoring ecosystem to match. Their <a href="/7548-seachoice-anchors-200101">Anchors</a> lineup includes a wide variety of styles suited to different bottom types and vessel sizes — from lightweight folding grapnel anchors ideal for personal watercraft to hot-dipped galvanized plow anchors engineered for boats in the 24-to-31-foot range. For boaters who need a permanent or semi-permanent solution, Seachoice&quot;s <a href="/7548-seachoice-mooring-anchors-200693">Mooring Anchors</a> are cast from heavy iron and sized for vessels from small runabouts all the way up to large cruisers, with improved shaft designs and oversized eyes to accommodate heavy-duty shackles.</p><p>For those who prefer traditional styles, the <a href="/7548-seachoice-slip-ring-traditional-anchors-200970">Slip Ring &amp; Traditional Anchors</a> collection offers classic navy and river anchor designs, many featuring vinyl or PVC coating for corrosion resistance in both fresh and saltwater environments. Whether you&quot;re anchoring in sand, gravel, shale, or soft mud, Seachoice has an anchor engineered for the job.</p><h3>Marine Rope and Cordage</h3><p>No anchoring system is complete without reliable cordage, and Seachoice&quot;s <a href="/7548-seachoice-rope-17207">Rope</a> category delivers just that. From solid-braid nylon dock lines that are rot-proof and abrasion-resistant to hollow-braid polypropylene anchor lines for smaller boats and PWC applications, Seachoice rope products are built for the demanding conditions of the marine environment. UV protection and corrosion-resistant hardware are standard features across the lineup, ensuring longevity whether you&quot;re in freshwater lakes or open saltwater.</p><h3>On-the-Water Comfort: Coolers &amp; Ice Chests</h3><p>A great day on the water also means keeping food and drinks cold, and Seachoice&quot;s <a href="/7548-seachoice-coolersice-chests-200288">Coolers/Ice Chests</a> round out the brand&quot;s on-board comfort offerings. Designed with the marine environment in mind, these coolers are built to handle sun, spray, and the rigors of life aboard a boat.</p><h3>A Brand You Can Count On</h3><p>Seachoice operates with a simple promise: quality you can trust, backed by worry-free protection. With a product line that spans lighting, electrical components, safety gear, hardware, anchoring, and more, Seachoice continues to be the brand boaters reach for when reliability matters most.</p>

Product Details

The Seachoice 50-18171 is a molded plastic thru-hull fitting designed with a broad flange for secure installation through boat hulls and decks. Manufactured to meet ABYC (American Boat and Yacht Council) safety standards for small craft, this fitting provides a reliable connection point for hoses and plumbing systems.

Key Features:

  • Durable molded plastic construction resists corrosion in marine environments
  • Broad flange design provides increased surface area for stronger, leak-resistant mounting
  • Meets ABYC safety standards for small craft construction
  • Suitable for above-waterline applications including livewell drains, bilge pump outlets, and deck drains

Important: This fitting is not recommended for use below the waterline. It is designed for above-waterline applications only to ensure safe operation and prevent potential hull breaches.

The broad flange design makes installation easier by distributing stress across a wider area, reducing the risk of cracking or pull-through on fiberglass or composite hull materials.
