Attwood Marine

<h3>About Attwood Marine</h3><p><strong>Attwood Marine</strong> has been a cornerstone of the boating world for over a century. Founded with a commitment to quality engineering and practical design, Attwood grew from manufacturing underwater hardware and on-deck fittings into one of the most recognized names across every segment of the marine accessories market. Today, the brand operates as part of the Navico Group by Brunswick — a global family of market-leading marine companies — yet it has never lost the focused, boater-first philosophy that built its reputation.</p><p>What sets Attwood apart is their end-to-end approach: they design, manufacture, test, and distribute their own products rather than simply resourcing components from third parties. Every product in their catalog is tested against the highest U.S. Coast Guard (USCG), American Boat and Yacht Council (ABYC), and CE standards, giving boaters and OEM boat builders alike the confidence that Attwood parts will perform when it matters most. Corrosion-resistant materials — including 304 and 316 stainless steel, chrome-plated zinc, and marine-grade synthetics — are used throughout the lineup to ensure durability in both freshwater and saltwater environments.</p><p>Attwood is also a leading OEM supplier, meaning you'll find their components pre-installed on boats straight from the factory. That pedigree speaks volumes: when boat manufacturers trust a brand to equip new vessels, that's a strong vote of confidence for the aftermarket buyer as well.</p><h3>Attwood Marine Product Categories</h3><p>Attwood's catalog spans a remarkably broad range of marine needs. On the docking and mooring side, their <a href="/7239-attwood-marine-fenders-201953">boat fenders</a> provide reliable hull protection against docks, pilings, and other vessels — an essential piece of gear for any boat owner. For on-water comfort and cockpit organization, Attwood's <a href="/7239-attwood-marine-seat-pedestal-packages-202496">seat &amp; pedestal packages</a> deliver complete seating system solutions backed by years of ergonomic engineering, while their <a href="/7239-attwood-marine-seat-clamp-mounts-202497">seat clamp mounts</a> and <a href="/7239-attwood-marine-seat-clamp-mounts-200927">mounting hardware</a> make swapping or positioning seats quick and secure. Rounding out the seating ecosystem, Attwood's broad selection of <a href="/7239-attwood-marine-seating-table-parts-accessories-202501">seating &amp; table parts and accessories</a> keeps every swivel, slide, and fitting performing at its best season after season.</p><p>Beyond seating and docking, Attwood is well known for its bilge and aerator pumps (including the iconic Sahara Mk2 and Tsunami series), navigation lighting, fuel systems, rod holders, and trailering accessories — making it a one-stop resource for outfitting or refreshing virtually any powerboat, fishing boat, or recreational vessel.</p><h3>Why Boaters Trust Attwood</h3><ul><li><strong>100+ years of marine expertise</strong> — a track record that few brands can match</li><li><strong>USCG, ABYC &amp; CE certified</strong> products built to rigorous safety and performance standards</li><li><strong>OEM-preferred supplier</strong> to leading boat manufacturers worldwide</li><li><strong>Corrosion-resistant construction</strong> engineered for saltwater and freshwater environments</li><li><strong>Full design-to-distribution control</strong> ensuring consistent quality across every product</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.
