Newmar WPF-3 1.5WATERPROOF Fitting
Newmar WPF-3 1.5WATERPROOF Fitting — Product description
Ensuring a reliable, watertight seal for cables entering enclosures is crucial in demanding environments like industrial setups, marine applications, or areas prone to moisture and dust. The WPF-3 waterproof fitting from Newmar delivers top-tier protection with its robust compression design, achieving full IP68 ratings for complete submersion resistance. Ideal for cables ranging from 0.55" to 0.98" in diameter, this fitting pairs perfectly with PG-29 enclosure knockouts, providing a secure, hassle-free installation that stands up to vibration, corrosion, and extreme conditions.
Standout Features of the WPF-3 Waterproof Fitting
- Superior Sealing Technology: Compression hub grips cables tightly, forming an impenetrable barrier against water ingress while allowing easy wire passage.
- Secure Mounting: Retaining nut locks firmly to enclosure walls, preventing loosening over time—even under constant mechanical stress.
- Versatile Compatibility: Matches standard PG-29 knockouts, integrating seamlessly with explosion-proof (EX-rated) enclosures commonly used in hazardous locations.
- Durable Construction: Built from high-grade materials resistant to chemicals, UV exposure, and temperature swings, ensuring long-term reliability without frequent replacements.
- Quick Assembly: No special tools required beyond basic wrenches, minimizing downtime during setup or maintenance.
Technical Specifications Across the WPF Series
The WPF lineup offers scalable options for various cable sizes and enclosure types. Here's a breakdown:
| Model | Cable Diameter Range | Mounting Hole Diameter | EX Enclosure Knock-Out Size Ref. |
|---|---|---|---|
| WPF-1 | 0.20" - 0.47" | 0.91" (22.5 mm) | PG-16 |
| WPF-2 | 0.35" - 0.71" | 1.14" (29.0 mm) | PG-21 |
| WPF-3 | 0.55" - 0.98" | 1.48" (37.5 mm) | PG-29 |
Ideal Applications for WPF-3 Fittings
Engineers and technicians rely on these fittings in scenarios where environmental hazards threaten electrical integrity:
- Outdoor control panels exposed to rain, snow, or washdowns.
- Offshore equipment and shipboard systems battling saltwater corrosion.
- Hazardous area enclosures in oil & gas, chemical plants, or mining operations.
- Heavy machinery housings subject to vibration and high-pressure cleaning.
- Telecom cabinets in remote, weather-beaten locations.
By preventing moisture migration, WPF-3 extends equipment lifespan and reduces costly failures, making it a smart upgrade over basic bushings or grommets.
Step-by-Step Installation Tips
- Prepare the enclosure: Drill or punch a hole matching the 1.48" (37.5 mm) mounting diameter, or use PG-29 knockouts.
- Feed cable through the fitting: Insert wire until it exits the opposite end, ensuring 0.55"-0.98" diameter compatibility.
- Assemble components: Slide the compression hub over the cable, then thread the body into the retaining nut.
- Mount to enclosure: Position the fitting, hand-tighten the nut, then use wrenches for a firm seal (torque per enclosure specs).
- Tighten compression: Rotate the hub clockwise to grip the cable—avoid over-tightening to prevent damage.
- Test: Perform a water spray or submersion check to confirm IP68 integrity.
Pro Tip: Apply a thin layer of silicone lubricant to threads for smoother installation and enhanced sealing.
Why Choose WPF-3 Over Standard Cable Glands?
Unlike generic pass-throughs that compromise on seal quality, WPF-3 combines ease-of-use with industrial-grade performance. It eliminates the need for potting compounds or adhesives, saving time and mess. Users report fewer leaks and callbacks compared to multi-piece alternatives, thanks to its one-piece compression mechanism. For projects demanding NEMA 6P or equivalent submersion protection, this fitting checks every box without breaking the bank on premium alternatives.
Frequently Asked Questions
What IP rating does the Newmar WPF-3 provide?
The WPF-3 achieves a full IP68 rating, suitable for continuous immersion in water beyond 1 meter.
What cable sizes fit the WPF-3 waterproof fitting?
It accommodates cables from 0.55 inches to 0.98 inches in outer diameter, ideal for mid-to-large power or data lines.
Is the WPF-3 compatible with explosion-proof enclosures?
Yes, it references PG-29 knockouts, commonly used in EX-rated enclosures for hazardous environments.
How do I install the WPF-3 fitting correctly?
Drill a 1.48-inch hole, thread cable through, assemble nut-body-hub, tighten securely, and test for leaks.
Can WPF-3 handle corrosive environments?
Absolutely—its rugged materials resist chemicals, salt spray, and UV, perfect for marine or industrial use.
What's the difference between WPF-2 and WPF-3?
WPF-3 handles larger cables (0.55-0.98") with a 1.48" hole for PG-29, while WPF-2 is for 0.35-0.71" cables and PG-21.
Does it require any special tools for installation?
No, standard wrenches suffice; no adhesives or complex tooling needed.
Waterproof Fittings
For complete waterproof assembly (IP68) use these compression fittings. Retaining nut secures fitting to enclosers, compression hub creates waterproof seal around wires. Various sizes are available in a wide range of cable diameters.
| Model | Cable Diameter Range | Mounting Hole Diameter |
EX Enclosure Knock-Out Size Ref. |
| WPF-1 | .2?-.47? | .91" (22.5 mm) | PG-16 |
| WPF-2 | .35?-.71? | 1.14" (29.0 mm) | PG-21 |
| WPF-3 | .55?-.98? | 1.48" (37.5 mm) | PG-29 |
