1.Product Description

Ingiant Technology’s liquid slip ring is specifically engineered for marine equipment scenarios, boasting outstanding core parameters and performance advantages, making it an ideal choice for rotary fluid connection in ship systems.

Equipped with 2 fluid channels (X1, X2) and G1-1/2 threaded interfaces, it is designed for water media with a flow rate of 40mm, perfectly meeting the multi-loop medium transmission needs of marine hydraulic and cooling systems.

With a design pressure of 10MPa and working pressure of 1MPa, it features stable pressure resistance to adapt to the complex marine working conditions of ships. Operating at 10RPM, it achieves smooth transmission without jamming under low-speed rotation, suitable for various rotary equipment on ships.

Crafted from stainless steel, the slip ring effectively resists marine salt spray corrosion. Its operating temperature range of -28℃ to +80℃ ensures compatibility with global marine navigation environments, maintaining reliable performance in extreme temperature conditions.

For added convenience, the product comes with 2 M12 eye bolts for easy installation. Designed strictly according to marine environmental conditions, its reliability has been rigorously verified, providing a high-quality and durable solution for liquid rotary connection in marine equipment.
