PG21 Cable Waterproof Gland Connector

Extra-Large-Diameter Cable Accommodation: Engineered to clamp and seal heavy-duty cables ranging from 13mm to 18mm in diameter (28.3mm thread mounting diameter), catering to high-current power feeds and dense industrial wiring harnesses.

IP68 Industrial Waterproof & Dustproof Seal: Provides complete ingress protection against water immersion, high-pressure spray, dust, and airborne contaminants, maintaining internal safety in extreme conditions.

Integrated Rubber Washer & Locknut Seal: Features a resilient internal NBR rubber washer and heavy-duty locknut gasket that form a 360° airtight seal around entry cutouts and thick cable jacketing.

Robust Mechanical Strain Relief: Internal claw clamping jaw absorbs axial pulling forces and heavy mechanical vibrations, protecting interior screw terminals and solder points from wire detachment and stress.

Flame-Retardant Polyamide Nylon (PA66) Body: Constructed from high-strength PA66 polyamide plastic (UL94V-2 rated) that resists physical impacts, chemical exposure, oils, and long-term UV exposure.

Tool-Free Threaded Pass-Through Design: Threaded body construction allows quick hand-tightening or wrench securing through standard panel knockouts without requiring specialized installation tools.

Body & Locknut Material: Industrial-grade polyamide nylon (PA66).

Sealing Gasket Material: High-density NBR rubber sealing ring.
