Liquid Tight Blanking Plugs

Liquid tight blanking plugs, also known as rubber blanking plugs or waterproof hole plugs, are specialised sealing components designed to provide complete protection against water, oil, and environmental ingress. These TPE rubber plugs are engineered to seal unused mounting holes and access points in panels, enclosures, and equipment across multiple UK industries including marine, automotive, electrical, telecommunications, and outdoor infrastructure. The primary function of these liquid tight plugs is to create an impermeable barrier that prevents moisture, dust, chemicals, and debris from entering sensitive systems whilst maintaining IP68 waterproof standards for submersible applications.

Manufactured from premium Thermoplastic Elastomer (TPE) rubber, these liquid tight blanking plugs deliver exceptional durability and chemical resistance. Available in Shore A hardness ratings of 75 and 85, they provide the perfect balance between flexibility for easy installation and structural integrity for long-term sealing performance. Each plug features a UL94V-0 flammability rating and UL certification, ensuring compliance with stringent UK safety standards for outdoor and industrial applications. The innovative tapered shank design allows for effortless hand installation without additional tools, whilst the temperature resistance range of -60°C to 135°C makes them suitable for extreme British weather conditions and industrial environments.
