This is a multi-hole waterproof gasket. It’s made for solar connectors. It’s used a lot in different connector scenarios of solar photovoltaic power generation systems. Like solar panels, solar energy storage equipment, and solar-powered vehicles or mobile photovoltaic devices.It’s a core part of
Solar Connector Sealing Parts and
Outdoor Waterproof Connector Seal. It has an overall flat block shape. There are multiple columnar protrusions on it. These protrusions are either hollow or solid. They’re designed to fit the holes of connectors. The block part works as a base. The protrusions and the base are made in one piece. The outer side of the protrusions has annular grooves. These grooves can be used to make sealing better or fit the clamping grooves of connectors.The overall structure is regular. The positions of the holes (which are the protrusions) are arranged in an orderly way. This makes it easy to match precisely with the interface of solar connectors. It also meets the functional requirements of
Connector Gasket and
Interface Sealing Parts.

1. Product Functions
1)Waterproof Sealing:You insert the columnar protrusions into the holes of the connector. Then the base fits closely with the connector surface. It uses the material’s elasticity and structural design. Like the compression deformation of annular grooves. This fills the gaps in and around the connector holes. It stops moisture, dust, sand, and other things from getting into the interior of the connector. This protects the electrical connection parts of the connector. It avoids problems like short circuits and corrosion. Its waterproof performance meets the strict standards of
Waterproof Connector Seal and
Sealing Grommets for Connections in outdoor electrical systems.
2)Dust and Foreign Object Protection:It works as a physical barrier against external foreign objects. Like dust and sand particles. This keeps the inside of the connector clean. It makes sure the electrical connection of solar connectors is stable and reliable. It also makes the connectors last longer. This protective effect helps with the barrier role of
Connector Interface Seals in keeping the connector intact.
3)Positioning and Organization:The multi-hole structure matches the holes of the connector exactly. This lets it play a positioning role. It organizes the installation of the connector’s parts. Like pins and cables. It makes this installation neater. This helps improve the accuracy and efficiency of solar connector assembly. It also reduces connection failures caused by wrong installation positions. This positioning function meets the assembly auxiliary requirements of
Mini Rubber Seals for Connector.

2. Product Performance Characteristics
1)High Adaptability:It has very high dimensional accuracy. The positions, diameters, and protrusion heights of the multiple holes match the holes of solar connectors strictly. This makes sure it can be inserted precisely and fit tightly. It won’t loosen or move after installation. This adaptability is the same as the precision matching requirements of Solar Connector Sealing Parts and Connector Gasket.
2)Excellent Sealing Performance:The material has good elasticity and can be compressed to change shape. After being compressed, it fills gaps tightly. This achieves effective waterproof and dustproof effects. It usually needs to meet certain waterproof grades. Like IP67 or IP68. Solar connectors used outdoors for a long time generally need IP67 or above. This helps them deal with scenarios like rain immersion. Even when the temperature changes or there’s vibration, its sealing performance stays stable. No leakage happens. This sealing reliability is as good as that of Waterproof Connector Seal and Outdoor Waterproof Connector Seal.
3)Weather Resistance:It fits complex outdoor climatic conditions. It resists ultraviolet radiation. It won’t get old or become brittle after being exposed for a long time. It resists mildew and hydrolysis in high-humidity environments. It also tolerates ozone. After being used for a long time, its physical and chemical properties stay stable. Its waterproofness, elasticity, and strength won’t get worse significantly. This weather resistance meets the durability standards of Outdoor Waterproof Connector Seal in harsh outdoor environments.
4)Electrical Insulation:The material has excellent electrical insulation performance. It has a high surface resistivity. Usually, this resistivity needs to be ≥1012Ω?m. This stops electrical failures. Like connector short circuits and leakage caused by the waterproof gasket being conductive. It makes sure solar systems and personnel are safe. This insulation property is a key requirement for Sealing Grommets for Connections and Connector Interface Seals in electrical systems.
5)Chemical Corrosion Resistance:It can stand chemical substances that may be encountered in solar systems. Like residual cleaning agents on the surface of photovoltaic modules, trace leakage of battery electrolytes, and acid rain components in the air. It won’t have chemical reactions with these substances. It keeps its structure and performance intact. This corrosion resistance meets the material standards of Solar Connector Sealing Parts in complex chemical environments.
6)Mechanical Strength and Elasticity:It has moderate mechanical strength. It resists damage and breakage during pressing. It also resists damage when being inserted or taken out during installation. At the same time, it has good elasticity. After being compressed and deformed, it can bounce back to its original shape quickly. This lets it keep sealing and protection effects continuously. During the transportation, installation, and operation and maintenance of solar equipment, its structure stays stable. The protection function won’t fail. This mechanical performance meets the durability requirements of Mini Rubber Seals for Connector and Connector Gasket.
7)High and Low Temperature Resistance:It keeps stable performance within the operating temperature range of solar equipment. Like from -40℃ to 85℃. The surface temperature of photovoltaic panels in desert areas may be higher in summer. At high temperatures, it won’t soften or flow. At low temperatures, it won’t become brittle or crack. This makes sure the waterproof sealing and protection functions work effectively all the time. This temperature resistance meets the environmental adaptability requirements of Outdoor Waterproof Connector Seal and Solar Connector Sealing Parts.
