Waterproof Ring Back Cover Seal for Outdoor Connectors and Enclosures 0.5mm to 0.9mm Thick Sizes 12mm to 40mm Various Colour Options
Waterproof Ring Back Cover Seal for Outdoor Connectors – Silicone, Sizes 12-40mm

This waterproof ring back cover seal is designed to provide a dependable barrier against moisture for outdoor electrical connectors and enclosures. Made from flexible silicone, it fits into grooves of back covers to create a compression seal that helps protect sensitive electronics from rain, splashes, and condensation. With thicknesses ranging from 0.5mm to 0.9mm and diameters from 12mm to 40mm, you can select the precise variant to match your housing dimensions.
Features and Construction

The ring is constructed from a single piece of silicone, chosen for its ability to compress and conform without permanent deformation. No adhesives or tools are needed for installation, making it suitable for field assembly.
Material and Build
Silicone offers good resistance to temperature variations and maintains its flexibility over time. The ring is moulded as a continuous loop, ensuring a consistent cross-section around its circumference.
Size and Practical Fit
Available in five thickness steps (0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm) and a diameter range of 12mm to 40mm, the ring can accommodate a variety of groove depths and housing openings. Select the variant that matches your cover's groove measurements.
Uses and Placement

This ring is primarily intended for use in outdoor or industrial enclosures where a simple, replaceable seal is needed. It is suited for both professional installations and DIY projects involving weatherproofing.
Event or Professional Use
For electricians, installers, and maintenance teams, having a selection of ring sizes on hand allows quick replacement of worn or missing seals on site. The silicone material does not stick to surfaces, making removal and refitting straightforward.
Everyday Home Use
Home users working on garden lighting, security cameras, or outdoor junction boxes can use this ring to improve the water resistance of existing enclosures. Its simple design requires no special skills to fit.
Benefits and Buying Value

The main benefit of this waterproof ring is its ability to provide a direct replacement or upgrade for the back cover seals in many standard enclosures. By choosing the correct thickness and diameter, you can restore or improve the seal without replacing the entire housing.
Reuse and Low Maintenance
Silicone does not degrade quickly under normal outdoor conditions and can be installed and removed multiple times without losing its shape. No regular maintenance is required beyond periodic visual checks.
Why Choose This Product
Rather than buying a complete new enclosure, replacing a single seal ring is a cost-effective way to maintain weather protection. The range of sizes ensures you can find a match for many common back cover grooves.
