Liquid Tight Bushings
Liquid Tight Bushings—also known as liquid tight strain relief bushings—are precision-moulded components combining Nylon 6/6 and TPE rubber to secure and seal cable penetrations in panels, enclosures, control cabinets, and machinery. Designed for cable diameters from 7.1 mm to 11.2 mm, they feature UL 514B approval, IP 68 ingress protection (tested to 25 psi for 24 hours), and UL 94 V-2 flame retardant rating. UK sectors such as industrial automation, electrical appliance manufacturing, automotive assembly, outdoor lighting, telecoms and networking widely adopt these bushings for their ability to provide strain relief, abrasion resistance, chemical resistance, and waterproof sealing—all within a discreet 4.8 mm low-profile design.
Available Materials & Style Options
- Nylon 6/6 body with co-moulded black TPE sealing head
- Low-profile snap-in design (approx. 4.8 mm protrusion above panel)
- Includes nylon adaptor and pliers for precision installation
- Cable diameter sizes: 7.1 mm to 11.2 mm
- Panel thickness compatibility: 3.2 mm to 4.8 mm
Key Features & Benefits
- IP 65/66/67/68-rated sealing: protects against dust and water ingress in harsh environments
