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.
| 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.
Setting up the DX-3 is straightforward, but a few pro tips ensure a bulletproof seal:
Pro Tip: Lubricate the neoprene lightly with silicone spray for smoother insertion, especially with sticky connectors.
The DX-3 shines in scenarios where standard glands fall short:
Users love how it cuts installation headaches—fewer fittings mean less clutter and weight, plus superior IP-rated sealing that outlasts cheaper alternatives.
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.
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.
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.
Yes, the neoprene construction and stainless hardware resist corrosion, making it perfect for boats, yachts, and coastal setups.
Compress the gland firmly by tightening the fitting, then test with water pressure. The neoprene molds tightly around cables for reliable IP67-level protection.
Up to 1.65" max diameter—slit carefully around the connector base for a snug fit without gaps.
A sharp step drill bit or conical reamer works best for clean, tapered holes that seal evenly. Avoid dull tools to prevent tearing.
Provided with solid neoprene cable gland, installer drills holes and slits as required to
accommodate cable with or without factory installed connector. Multiple cables may be passed through a single fitting.
