Attwood Marine

<h3>About Attwood Marine</h3><p><strong>Attwood Marine</strong> has been a cornerstone of the boating world for well over a century. <a href="/7239-attwood-marine">Founded in 1893</a>, the company began by manufacturing precision underwater hardware and on-deck fittings — rudders, struts, cleats, and lights — and quickly earned a reputation for fine engineering and enduring quality. After World War I, the brand's craftsmanship was so well regarded that legendary boatbuilder Chris-Craft turned to Attwood for brass fittings on their iconic pleasure boats.</p><p>Today, Attwood operates as part of the Navico Group by Brunswick, a global family of industry-leading marine companies, yet it has never lost the boater-first focus that built its name. What distinguishes Attwood from many competitors is their end-to-end philosophy: they design, manufacture, test, and distribute their own products rather than simply sourcing components from third parties. Every item in the Attwood catalog is rigorously tested to meet or exceed U.S. Coast Guard (USCG), American Boat and Yacht Council (ABYC), and CE standards — giving boaters and OEM manufacturers alike the confidence to rely on Attwood gear season after season.</p><h3>A Complete Marine Accessories Ecosystem</h3><p>Attwood's catalog spans an impressively broad range of marine needs. On the comfort and ergonomics side, their <a href="/7239-attwood-marine-seat-pedestal-packages-200926">Seat &amp; Pedestal Packages</a> deliver complete, ready-to-install seating system solutions backed by decades of engineering refinement. For boaters who prefer to build or customize their setup, Attwood's <a href="/200999-pedestals-fixed-mount-attwood-marine-7239">Fixed Mount Pedestals</a> provide a sturdy, reliable foundation engineered for lasting stability on the water.</p><p>When it comes to protecting your hull at the dock, Attwood's <a href="/7239-attwood-marine-fenders-200396">Fenders</a> offer dependable, marine-grade cushioning against docks, pilings, and other vessels — an often-overlooked but essential piece of gear for every boat owner. Getting on and off the boat safely is equally important, and Attwood's <a href="/200179-boarding-ladders-attwood-marine-7239">Boarding Ladders</a> are designed with heavy-duty construction, rated hardware, and user-friendly features to make every entry and exit as secure as possible.</p><p>Beyond these categories, Attwood is also widely recognized for its bilge and aerator pumps, navigation lighting, fuel systems, rod holders, and trailering accessories — making the brand a true one-stop resource for outfitting or refreshing virtually any powerboat, fishing boat, or recreational vessel.</p><h3>Why Boaters Choose Attwood</h3><ul style="list-style:disc"><li><strong>100+ Years of Proven Experience</strong> — A heritage of quality engineering stretching back to 1893.</li><li><strong>Multi-Standard Compliance</strong> — Products tested to USCG, ABYC, and CE standards for safety and performance.</li><li><strong>OEM-Trusted</strong> — A leading supplier to major boat manufacturers across a wide range of product categories.</li><li><strong>Corrosion-Resistant Materials</strong> — Extensive use of 304 and 316 stainless steel, chrome-plated zinc, and marine-grade synthetics built for harsh saltwater environments.</li><li><strong>In-House Engineering</strong> — Advanced prototyping, simulation, and real-world testing ensure reliability before any product reaches the water.</li></ul>

Product Details

The Attwood Marine 3872-3 is a high-quality thru-hull connector designed for 5/8" hose applications on boats and marine vessels. This essential marine hardware component provides a secure, watertight connection for hoses passing through the hull.

Key Features:

  • Constructed from rugged molded plastic for long-lasting durability
  • Corrosion-resistant material will not rust, discolor, or contribute to electrolysis
  • Engineered design prevents unsightly hull streaking
  • Allows for countersinking to achieve a flush-mounted installation wherever required
  • Fits standard 5/8" marine hose
  • Clean white finish blends with most hull colors

This thru-hull fitting is ideal for livewell systems, bilge pump discharge, washdown applications, and other marine plumbing needs. The non-metallic construction eliminates concerns about galvanic corrosion, making it perfect for saltwater environments.

Happy Halloween

Had a hitch that no one seemed to have at a reasonable price.

I ordered a chrome brake light cover from Autoplicity 3 days ago and received it today. Their add showed the piece I wanted clearly and it arrived today exactly as I expected. It looks great on my new Dodge truck. Thanks for the great service!

Autoplicity is a great merchant to do business with. They stock a wide variety of high performance parts at rock-bottom prices, and they ship quickly without any hassles. They are a pleasure to deal with.

Great customer service, ships fast. Will buy from again

1st time customer. Hope to use again.

easy and honest to deal with...no problems and fast shipping.

I ordered a windshield wiper fluid reservoir. It came on time and was the product I needed. It fit perfectly and works great.

Purchased a CTEK 7002 battery tender because of how great they work for keeping all the toys charged up over the cold months. Autoplicity had, by far the best price on this product. Couldn't ask for more.

thanks

Sales person was very helpful finding my old order and taking a new order for the same pump. Good prices. I will order again. thank you. John

Very easy and fast checkout

Rock-bottom price and fast shipping. So far, so good.

** Update 4/18/2012<br>Everything arrived in several different shipments. I did experience a problem with some FelPro Headbolts that I had ordered. I ordered two and only received one, but after a short phone call with Paul from shipping, the problem was fixed and my second set of bolts were shipped.<br><br>They had the cheapest price that I could find on several products. I did not like the order confirmations on there website as I had to copy and paste to search for my tracking number. I am supposed to receive my order today and I am scared because the two weights do not match up. Autoplicity says 37.7 pounds and fedex says 3.8 pounds. Maybe there is more than one tracking number and I just do not know.
