Description
Overview:
This rubber seal is a flat coupling washer designed to keep hose joints tight and leak‐free in air, water, and general utility hose systems. Made from durable black rubber, it sits between coupling faces to create a dependable seal that prevents loss of pressure or fluid. With an outer diameter of 34mm, an inner diameter of 19mm, and a thickness of 10.6mm, it is sized for common hose couplings used on site tools and workshop equipment. Suitable for construction, plant, and maintenance use, it supports reliable operation of pneumatic and fluid-transfer setups. It is often used on tools such as breakers and tampers, and is compatible with selected models including CP222 and CP9. Manufacturer Part Number (MPN): 816 200.
