Product Details

The Attwood Marine 66543-3 is a premium thru-hull fitting designed for above-waterline marine applications requiring a 1-1/8 inch hose connection. This short-length fitting provides a secure, watertight passage through boat hulls for plumbing, livewell systems, and washdown installations.

Key Features:

  • Cast from marine-grade 316 stainless steel for superior corrosion resistance in harsh saltwater environments
  • Integrated channel under the flange designed to hold a bead of marine sealant for enhanced watertight integrity
  • Wrench flats or end notch for easy installation and secure tightening
  • Short body design ideal for installations with limited space behind the hull
  • Accepts 1-1/8 inch ID hose for reliable fluid transfer

Important: This fitting is engineered for above-waterline installations only and should not be used for below-waterline applications. Always use appropriate marine sealant during installation to ensure a proper seal.

Attwood Marine products are trusted by boaters worldwide for their durability and reliability in demanding marine conditions. This thru-hull fitting delivers the quality construction needed for safe, long-lasting performance.

Great experience

perfect

fairly easy, shipping was expensive though

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

THANKS SO FOR GOOD PRICE

Good price.

Pricing was good and customer service quick to respond.
