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
- UL 514B listing and UL 94 V-2 flame rating ensures compliance with safety standards
- Low-profile, pre-assembled design speeds up installation and maintains aesthetics in compact systems
- Robust performance from –20 °C to +100 °C temperature range
- TPE head resists oils, chemicals, UV, and abrasion
- Strain relief compliant: protects cables against kinking, pulling, twisting—UL-rated
- Smooth internal edges reduce cable wear and simplify insertion
- Snap-in and pliers-assisted options cater to manual and high-volume assembly needs
Common UK Use Cases
- Sealing cable entries on industrial control panels in automated manufacturing facilities
- Waterproof cable pass-throughs in outdoor LED signage, street lighting, and solar arrays
- Strain relief and protection for cabling in electric vehicle battery enclosures and chargers
- Securing internal wiring in domestic appliances, HVAC units, or coffee machines
- Cable penetration protection in telecom, networking cabinets, or data centre racks
