Versatile Waterproof Cable Routing with Newmar DX-3 Feed-Thru Fittings

Engineered for demanding environments like marine vessels, RVs, and industrial setups, the Newmar DX-3 feed-thru fitting delivers reliable waterproof protection for your cable installations. Unlike rigid passthrough options, this fitting uses a solid neoprene gland that lets you customize it on-site—simply drill or slit to fit cables with or without bulky connectors. It's a go-to solution when you need to bundle multiple wires through one compact hole without compromising the seal.

Whether you're retrofitting an older boat console or organizing wiring in a custom camper van, the DX-3 simplifies the process while ensuring long-term durability against saltwater, vibrations, and harsh weather.

Standout Features of the DX Series

Customizable Neoprene Seal: Drill precise holes or slits to accommodate any cable diameter or connector size—no pre-drilled limitations.
Multi-Cable Capability: Route several cables through a single fitting, saving panel space and reducing installation time.
Robust Waterproof Design: Neoprene material compresses tightly around wires, blocking moisture even under pressure.
Easy Installer-Friendly Setup: Similar to the CCX series but with user-defined openings for ultimate flexibility.
Compact and Sturdy Build: Handles tough conditions without cracking or leaking over time.

DX-3 Technical Specifications

Model	Drill-Thru Aperture	Max. Connector Diameter
DX-3	1.65"	1.65"

Aperture size refers to the recommended panel hole; the neoprene gland allows for cables up to the max connector diameter once customized.

Step-by-Step Installation Tips for Flawless Results

Setting up the DX-3 is straightforward, but a few pro tips ensure a bulletproof seal:

Measure and Drill the Panel: Use the 1.65" aperture as your guide for the bulkhead or enclosure hole.
Prep the Gland: With a sharp utility knife or step drill bit, create slits or holes matching your cable jackets and connectors. Test-fit without forcing.
Thread Cables Through: Pass wires from one side, then slide the gland into the hole from the opposite side.
Secure and Tighten: Hand-tighten the fitting, then use a wrench for a snug compression—neoprene will mold perfectly around cables.
Test the Seal: Spray with water or use a hose to verify no leaks; adjust if needed.

Pro Tip: Lubricate the neoprene lightly with silicone spray for smoother insertion, especially with sticky connectors.

Ideal Applications and Real-World Benefits

The DX-3 shines in scenarios where standard glands fall short:

Marine Electronics: Feed power cables, GPS lines, and radar wires through decks or consoles without drilling oversized holes.
RV and Trailer Wiring: Bundle battery leads, solar inputs, and lighting harnesses in tight battery compartments.
Industrial Panels: Protect sensor and control cables in washdown environments or outdoor enclosures.

Users love how it cuts installation headaches—fewer fittings mean less clutter and weight, plus superior IP-rated sealing that outlasts cheaper alternatives.

Frequently Asked Questions

What makes the Newmar DX-3 different from standard cable glands?

The DX-3 features a solid neoprene gland you customize by drilling or slitting, unlike fixed-size glands. This allows multiple cables or irregular connectors through one fitting for versatile waterproof routing.

Can I use the DX-3 for multiple cables at once?

Absolutely—its design supports bundling several cables through a single 1.65" aperture. Just ensure slits don't overlap excessively to maintain the seal integrity.

What size hole do I drill in my panel for the DX-3?

Drill a clean 1.65" hole to match the feed-thru aperture. Use a hole saw for precision and deburr edges to prevent cable damage.

Is the DX-3 suitable for marine or saltwater environments?

Yes, the neoprene construction and stainless hardware resist corrosion, making it perfect for boats, yachts, and coastal setups.

How do I ensure a watertight seal after installation?

Compress the gland firmly by tightening the fitting, then test with water pressure. The neoprene molds tightly around cables for reliable IP67-level protection.

Can the DX-3 handle cables with large connectors?

Up to 1.65" max diameter—slit carefully around the connector base for a snug fit without gaps.

What's the best way to cut holes in the neoprene gland?

A sharp step drill bit or conical reamer works best for clean, tapered holes that seal evenly. Avoid dull tools to prevent tearing.
