Set of 2 14mm helical spring rubber seals for water pump. Mechanical seal 9 x 23 mm / 24 x 30 mm

Suitable for water pumps and mechanical seals, improves sealing reliability and reduces maintenance frequency.
The interface is 14 mm and the size is 9 x 23 mm/24 x 30 mm; please check carefully.
The integrated metal helical spring improves sealing performance, maintains a stable fit under high pressure or rotating environments, and prevents leaks.
The rubber material is oil-resistant, wear-resistant, and high-temperature resistant to ensure it won't age or crack easily during long-term operation.
It has good tolerance to water, coolant, light oil, and weakly acidic and alkaline environments, making it suitable for industrial and household equipment.
