The IP44 rating is one of the most important factors that determine the weatherproof capabilities of the garden socket. The "IP" stands for Ingress Protection, and the first digit (4) signifies protection against solid particles like dust, while the second digit (4) indicates protection against water splashes from any direction. This means that the 6-way garden socket is designed to resist dust particles from entering, preventing them from interfering with electrical components. The socket can withstand water splashes and light rain exposure, protecting it from moisture damage.

Waterproofing is enhanced by the inclusion of high-quality seals and gaskets, typically made of materials such as silicone, rubber, or neoprene. These seals are strategically placed around the socket’s cover, switches, and outlet points to form an airtight, watertight barrier. The seals prevent water, humidity, or condensation from entering the internal components of the socket, safeguarding the electrical connections and preventing short circuits.  The proper sealing ensures that the socket remains waterproof, effectively mitigating any potential risk of water infiltration that could cause rust, corrosion, or electrical failures.

The external casing of the 6-way IP44 garden socket is often constructed from durable, UV-resistant materials such as high-density polyethylene (HDPE) or polycarbonate. UV resistance is critical for outdoor electrical products, as prolonged exposure to sunlight can cause plastics to degrade, weaken, and become brittle over time. The UV-resistant housing ensures that the socket's casing maintains its structural integrity, does not crack or discolour, and continues to provide protection for the internal electrical components.

Internally, the components of the 6-way IP44 garden socket are typically made from materials resistant to corrosion, such as stainless steel or copper alloys with anti-corrosive coatings. These corrosion-resistant materials ensure that the metal contacts, wiring terminals, and connectors inside the socket do not rust or degrade when exposed to moisture, rain, or humidity. If the internal components were susceptible to corrosion, they could impair the socket's performance by disrupting the electrical connection or causing malfunctions.

Additional protective coatings are applied to the socket’s surface and internal components. These may include powder coating, anodizing, or other specialized treatments designed to offer an extra layer of protection against both environmental elements and physical wear. Powder coatings provide a durable, long-lasting finish that resists fading, scratching, and degradation caused by exposure to the elements. These coatings also prevent direct contact between metal surfaces and moisture, reducing the risk of rust and oxidation.
