InLine® Seal Set for M20 Power Cable Connectors, IP67, Rubber, 2-Pack, Black

For industrial electricians and maintenance crews working with M20 power cable connectors, achieving a reliable seal against dust and moisture is non-negotiable. This InLine® seal set delivers exactly that—two precision-moulded rubber gaskets that fit standard M20 x 1.5 threaded connectors, ensuring your connections stay protected in demanding environments. Whether you're wiring outdoor lighting, marine equipment, or factory machinery, these seals help maintain an IP67-rated enclosure when paired with compatible M20 cable glands.

Why choose it

These seals are engineered for long-term reliability. The rubber compound resists compression set, so the seal remains tight even after repeated cable insertions or temperature fluctuations. By preventing ingress of dust, dirt, and moisture, they extend the life of your connectors and reduce the risk of electrical faults. Installation is straightforward—simply place the gasket inside the connector body before tightening the cable gland. As a genuine replacement part, they restore the original sealing performance of worn or damaged M20 connectors.

Ideal use cases

• Outdoor electrical installations exposed to rain and humidity
• Industrial control panels and machinery with M20 cable entries
• Marine and coastal applications where salt spray is a concern
• Renewable energy systems, such as solar inverters and wind turbines
• Retrofitting existing M20 connectors to improve environmental protection

Good to know

Each pack contains two seals, enough for one connector or a spare. The seals are compatible with most standard M20 x 1.5 cable glands and connectors, but always verify your connector's thread specification before ordering. For best results, pair with an IP67-rated M20 cable gland and ensure the cable diameter falls within the specified 6–12 mm range. Store unused seals in a cool, dry place away from direct sunlight to maximise shelf life.
