Product Details

The Attwood Marine 3878-3 is a double-ended thru-hull connector designed to provide a watertight transition through bulkheads or tank walls. Constructed from durable polypropylene material, this fitting resists corrosion and provides reliable performance in marine environments.

Key Features:

  • Double-ended design for through-bulkhead or through-tank installations
  • Fits 3/4" marine hose
  • 5" overall length provides adequate thickness for most installations
  • Corrosion-resistant polypropylene construction
  • Creates watertight seal when properly installed

Important Installation Note: This thru-hull connector is designed for installation above the water line only. Not for below-waterline applications.

Ideal for livewell systems, baitwell plumbing, washdown systems, and other above-waterline marine plumbing applications where a watertight bulkhead penetration is required.

Excellent service and fast shipping. A seller I would do business with again.

Everything is super easy. A phone app would be nice, but this still works too

Shipping time sucks ass...... I ordered on Monday and I was told it ships 24 business hours after order. The item shipped late 3 day and will not receive my item until Wendsday a week and two days later talk about snail mail!!!!!! N

Cheaper than summitracing for arp headbolts. Fast processing and shipping.

Awesome experience! Lowest price and product was shipped right away.

Great

Great selection

First time like it so far

Did not receive a confirmation email when I placed the order so I was unsure if if the order had gone through properly. Part shipped the day after I ordered it. I received three confirmation emails at the that time for some reason. Overall I would say the experience ordering from Autoplicity was excellent and inspired confidence.

so far the experience has been great!

These guys had a great price on the Grote light I needed, they sent it out very fast. Item arrived fast and was well packaged, Great company!

Good prices, love the Amazon payments bc I use Amazon all the time
