Attwood Marine Thru-Hull Connector with Strainer, 3/4 in I.D., Acetal

Overview

The Attwood Marine 3886-3 is a white plastic thru-hull fitting with an integrated strainer for 3/4 in. inner diameter hose. It is used where an aerator pump needs a clean water path and some protection from debris before it reaches the pump.

This fitting uses an acetal body and installs through a 1-1/16 in. to 1-1/8 in. hole. The strainer threads onto the section beyond the external retaining nut, so it screens the intake without changing the basic thru-hull layout.

It is a practical match for above-water-line plumbing on smaller boats and fishing setups with aerator or livewell systems. The built-in screen helps cut down on grass, scale, and floating debris that can block flow and make pumps work harder than they should.

Key features

• Fits 3/4 in. I.D. hose for common aerator and livewell plumbing runs
• Integrated strainer helps keep debris out of the pump intake
• Acetal construction for a lightweight plastic fitting that suits wet marine environments
• White finish works well on many transoms, wells, and interior hull surfaces
• Installs in a 1-1/16 in. to 1-1/8 in. mounting hole
• Made for above-water-line thru-hull use
• Strainer mounts to the exposed threads beyond the retaining nut

Installation and fit

Before ordering, confirm that your hose measures 3/4 in. inner diameter and that your mounting location accepts the stated hole size. This is the main fit check for replacing an older aerator thru-hull or setting up a new line on a baitwell or livewell system.

Because the strainer sits on the outside, it helps when the intake is exposed to weeds, bait tank debris, or dockside growth. The strainer is not a replacement for the thru-hull connector nut, so installation should follow the normal thru-hull hardware arrangement.

Compatibility and use

This part makes sense for boaters running simple aerator plumbing where a compact screened thru-hull is easier to service than adding a separate external pickup or inline screen. It suits small fishing boats, skiffs, jon boats, and similar setups where above-water-line intake routing is part of the system layout.

If you are replacing an existing fitting, check hose size, mounting hole size, and the location on the hull or transom before purchase. Matching those points matters more here than brand-to-brand appearance, especially when space around the outside nut and strainer is limited.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
