Product Details

The Attwood Marine 38741 (3874-1) is a durable polypropylene thru-hull connector fitting designed for reliable marine plumbing installations above the waterline. This white marine-grade fitting provides a secure connection point for hoses passing through your boat's hull or deck.

Key Features:

  • Fits 1-1/8" to 1-1/4" inside diameter hose
  • Maximum hull thickness: 1-1/4"
  • Stem length: 3-1/4"
  • Flange diameter: 2-1/4"
  • Requires 1-3/8" installation hole
  • Polypropylene construction resists rust, corrosion, and discoloration
  • Will not contribute to electrolysis
  • Design eliminates hull streaking and allows countersinking for flush installations

Important: This plastic thru-hull connector is designed for installation above the waterline only. Not recommended for below-waterline applications. Ideal for bilge pump discharge, livewell drains, and other above-waterline plumbing connections on boats, RVs, and marine vessels.

Ordered my AC hose from here for the cheapest price. It fit and works perfectly! Pleased with fast delivery and will also be a future customer

Fast checkout

Pretty easy-to-use, delivery was not two day though.

Very good so far.

Picture did not match product sku #, but lowest price amongst competitors.

The shopping experience has been very simple and easy.

First time ordering from this site. So far everything looks good.
