Ensure your electrical enclosures stay fully protected in the harshest conditions with these high-performance waterproof compression fittings. Designed for seamless integration into explosion-proof (EX) enclosures, they deliver a reliable IP68 seal that withstands submersion, dust, and extreme environments. Whether you’re wiring up industrial control panels, marine equipment, or hazardous location setups, these fittings provide a secure, compression-style seal around cables without compromising flexibility or ease of installation.
Superior Sealing for Demanding Applications
These fittings feature a robust retaining nut that locks securely to your enclosure, while the compression hub molds tightly around individual wires or cables. This dual-action design eliminates gaps, preventing moisture ingress even under vibration, pressure washing, or prolonged exposure to corrosive elements. Crafted from durable, non-conductive materials like high-grade nylon, they resist chemicals, UV rays, and temperature swings from -40°F to 221°F, making them ideal for oil and gas, offshore platforms, wastewater treatment, and heavy machinery.
IP68 Rated: Submersible up to 10 meters for indefinite periods.
Multi-Cable Compatibility: Accommodates a range of diameters for versatile use.
EX-Ready: Matches standard PG knock-out sizes for quick retrofits.
Tool-Free Compression: Hand-tighten for most installs, with optional wrench for maximum torque.
Long-Term Reliability: No gels or potting compounds needed—pure mechanical seal.

Effortless Installation Steps
Getting a watertight seal is straightforward:
Drill or punch the enclosure to match the mounting hole diameter.
Feed cables through the fitting body.
Insert into the hole from inside the enclosure.
Slide on the compression nut and hand-tighten until snug.
Tighten further with a wrench (20-30 in-lbs torque) to compress the seal.
Test for seal integrity if required by your application standards.
Pro tip: For multi-conductor cables, strip outer sheath minimally to allow individual wires to fan out, maximizing the seal’s grip.
Real-World Performance and Versatility
Engineers in demanding sectors swear by these fittings for their no-fail performance. In marine applications, they shield against saltwater spray; in factories, they handle washdowns without leaking. Unlike cheaper alternatives that degrade over time, these maintain integrity through thousands of thermal cycles. They’re also a smart upgrade for legacy PG-threaded enclosures, bridging metric standards with modern wiring needs.
Frequently Asked Questions
What does IP68 rating mean for these waterproof fittings?
IP68 provides complete protection against dust and continuous immersion in water beyond 1 meter, making these fittings suitable for the toughest wet environments without leaks.
